You might have to take & early mark today ! I'll see what I can do ! The wiring diagrams in the Gregory's don't scan well, as there are so many fine lines. I find them very hard to read, with wires running all over the page, and then coming back to almost the same place. I find it easier to draw out the circuit for the one area of operation that you are interested in, rather than get confused with all the added stuff. It makes it easier to understand. I only worked out last night how to post a hand drawn sketch on Rollaclub, which I did for Xany. 5K Test Bed Wiring Diagram I'll sketch out the wiring of the headlight circuit, and post it soon, or if you PM to me a fax no: at work, I'll just fax it through. It might be clearer that way. I suspect from your previous posting on this problem, that the problem is in the column light switch stork unit, and is not probably the sort of thing you can easily fix at work without tools. However we might be able to find a workaround. :jamie:

Hi Simon ! The ignition is quite straight forward. The 5K has an electronic dizzy on it, with internal ignitor. It just has two wires coming out of it. The one with a red stripe on it is +ve, and goes to the coil +ve & the IGN terminal on the starter switch. The other wire goes to the coil -ve. I didn't have a spare ignition barrel / starter switch lying around with keys, but got a generic one from Auto Pro which has ACC, OFF, IGN, START just like any normal starter switch. Here is a rough sketch of the way I wired up my test bed. It works perfectly. I was also thinking about an electric pump, but opted in the end to use the standard mechanical one on the 5K engine. The fuel tank is one of those plastic 5 litre spare fuel containers you get from SuperCheap for $ 14.00. You can see it in the sixth pic above. Actually I pinched mine, from my better halfs car boot, but don't tell her; she hasn't missed it yet. About 2 meters of rubber fuel hose along the inside of the side bearer & she is sweet. I drilled a hole in the lid of the fuel container, so that hose is tight. A $ 2.00 fuel filter allows the fuel container/tank to breath. Any other questions Simon, just give me a yell. :D

Xany, the stand I built out of hardwood planks measures just 900mm wide by 1700mm long. It could well be a bit shorter, as it is only 1400 to 1500mm to the rear end of the g/box from the front. Even as it stands now, it will easily fit into a 6 x 4 box trailer. Here a couple more pics below, of more detail that might help you. I think you are in Brisbane northside, but if you want to have a look at the stand, your welcome to call by & have a look. I'm down at Greenbank (southside). The only thing I had to buy that I didn't have lying around from a donor car was a front crossmember, which 78 Rolla at Ipswich sold me a good KE70 one for $ 10 or $ 20, and an accelerator cable which I got on eBay for $ 12.00. All the rest came from the junk box. Oh, and a tin of black fence paint. The two supports for the radiator remove easily so that complete access to the front of the engine is possible If you have any queries, or want some more detailed pictures, just give me a yell. My six (6) year old wants to know when I am going to put the wheels & seat on it, so we can drive it. :D

Yeah Jamie. New topic for the test stand/dyno thingy. Got a feeling this thread could go on for some time. :D

New to this image thing, as I only recently got a digital camera. I notice there are a lot of sites that do on-line storage, but there are limits and restrictions on some, and others don't allow URL linking for placing pictures on forums like Rollaclub, and the likes of eBay etc. I'm doing a 2 week trial on Fotki at present, but would be pleased to hear from others who have used these services for some time, as to which they have found most sucessful & cheap or freeeeee! Freebies :D

Oh, and we'll need some virtual dashboard / dyno software ! Anyone seen any good cheap virtual instrument software, that we can hook up to this Dyno ? I've got access to plenty of data loggers & kilowatt hour measuring equipment. :D

I'll do a search on the web tonight & see if any one lists a home made engine Dyno. Wouldn't have to be too big. Maybe a water or drum dyno of some kind, like the chassis type, car wheel drive on ones. Water is very easy to control, as it's only a bit of plumbing & valves/taps etc. I can feel a project coming on ! :D

Thanks Jamie ! Next job after I get the ignition sensors going is to "map" the engine over a wide range of revs & loads, for optimum performance, to program the ECU. I'm open to any suggestions as to what I could get the tailshaft to drive stationary, to put a variable load on it. Things I might be able to get my hands on cheaply, could be a big water pump, which I could throttle it's output, or an electric generator driving some dummy variable loads. (fence wire in a 44 gallon of water =) ) Any thoughts greatfully accepted. :D

Thanks Guys ! Glad you like it. Well I have had a theory for a while that I could design & build a waste spark ignition for the K series, that did away with the distributor altogether, but avoided the complicated crank & camshaft angle sensors, common to other engines. I had proved it on the bench, but needed to go the next step, & fit to my 4KU engine. I had already decided that crank angle sensing off the crankshaft pully was not ideal, and I wanted to go flywheel sensing, due the larger diameter, & therefore less angular error. To work in this area experimentally, you need the engine out of the car. Not delighting in having the engine in & out of the car several times, besides the point that the KE55 is a daily drive for my better half, I decided a working test rig was the way to go. I toyed with the idea of a donor Corolla body with everything cut away, exposing the engine. for easy access. I then decided a test stand couldn't be too hard to build, and three bits of 200mm x 50mm hardwood planks from the nursery supplier, & a few 10mm coach bolts & screws from Bunnings, and there it was. It took about 4 hours to put together, designed on the run. Believe it Jamie, not a weld in sight, or required. It's totally self sufficent, and has wheels so it can be stored in the corner of the shed. Guages are a luxury, but for $ 15.00 for a set of 4 off 50mm units off eBay, I could not resist. Some of you might have noticed the hand accelerator made from the height adjustor of an old Rover 4 stroke lawnmower. I'm quite proud of it. Anyway, the 4KU came off for the 5K, which needs to go into the KE55 coupe soon as it's 4KC is on it's last legs. Then back with the 4KU and finish off the ignition system. Actually I experimented with the flywheel sensors today on the 5K, and they seem to work out well. I'll post you some pics tomorrow of the sensors I've tried today. I'd be very interested to hear from anyone out there at all, who has had a go at putting a waste spark or crank sensing on a K Series motor. :D

Andrew, I promised you I would post you a picture of the 5K engine, to show you how clean it is now ! To fill you all in. This engine came from a KE55 that had been done up by someone, unknown. A 5K & K50 g/box had been added and the interior done up. Anyway the cancer set in, and the car was doomed to be a "paddock basher" in a large orchard near Caloundra, where it was used to "get around" the orchard, on muddy tracks. When Andrew & I saw it, it had grass inside the car (growing I think) and you have never seen such a dirty engine. The car had more cancer that the Qld Health system, and there was only one place for the body. Back to Japan, to make more Toyotas. Anyway, has just been completely cleaned, stripped, checked, valve grind & head skim; tested & ready to drop into my KE55 coupe.

After telling you that all last night I quickly removed the fuse marked "LIGHTER" in my KE55 coupe this morning, to make sure that the couresty light & clock stopped. Nope ! Found that when I removed fuse called "TAIL LIGHTS" the clock & couresty lights went out, so obviously my Gregorys 184 manual is different to the car I've got. I'll have to do a bit more testing at the weekend, to see what each fuse powers. I note your Corolla is a 1984 KE70, so maybe the wiring is different again in those. Anyway, best suggestion is to remove all fuses one at a time & check with a test lamp, and I'm pretty sure you'll find it's one of them, as it is no coincidence that couresty lights & clock both stopped together. :jamie:

Hey ! I just had a quick look at the wiring diagram, and surprise, surprise; the clock & the courtesy light are both powered off the same fuse, which could explain why you have neither working. The fuse panel is usually just under the drivers dash. Even if the fuses look all intack, take out the fuse, bend the fuse holding clips back together & reinsert fuse. Swap a fuse, as sometimes they look OK, but have a fine break. The cigarette lighter is the only other thing on that fuse. If you find the lighter doesn't work, then power from the fuse block is probably the cause. Let us know how you go. I love Tamworth. :jamie:

Nice picture Fook ! What website did you see that one on ? I showed it to my little KE55 this morning in the garage, and she says, when she grows up, she wants to look like that ! :jamie:

I think Teddy loves DENSO spark plugs ! :)

If you think iridium plugs are dear, try buying a pair of double platinum plugs for "waste spark" systems, where the one coil powering two spark plugs results in the spark jumping from the centre to outer in one plug & from the outer to centre in the other. Some manufacturers produce the same plug in two different models. One has centre platinum electrode & the other an outer platinum electrode. This cuts down the amount of platinum required per plug, in that only one electrode is platinum. So in a 4 cylinder waste spark system where firing would be 1 & 4, & then 2 & 3, plugs 1 & 2 would use one model of plug & 4 & 3 would use the other other model. Confusing ? Here are a good couple of links that describe the waste spark & platinum plugs very well. Double Platinum Spark Plugs Waste Spark Explained

Here is a good link, which explains and answers many of the questions, user of spark plugs find a mystery. Read the FAQ on the top RHS of the page. NGK Spark Plugs ! :)

The question is "4WD Which one is good ? This one ! :( :D :lolcry:

Good one Teddy ! From experience give yourself a whole day to take it out, and another whole day to put it back in, if you are doing it for the first time. They are very frustrating, and as Teddy says, it's easy to break things, if you try to force them. The consolation is there are dashboards that are much much more difficult than the KE70. I once had to remove a RA40 Celica dash completely to replace a heater radiator coil. I still have nightmares about that ! Good luck !

I've been after a new vacuum guage, and have missed a few lately on eBay. Tonight I typed in "vacuum guage" in the search engine, as usual, and came up with this beaut little tune up kit. Vacuum Guage - ebay Trouble is, I can't quite work out which part of my 4K-C to attach it to. Can any one help ! It even says They must think it's so good, one of the other mechanics at work will want to steal it ! :( :D :lolcry:

I'd make him an offer, but it hasn't got a radiator. :( :D :lolcry: I know a lady with seven kids and she's got a saucepan than feeds the lot, that's not as big as that one upside down on top of the carby. I'd be worried about rebuilding it, incase a snake appeared out of the thermostat housing hose :lolcry: :D :D

KE-10 R.I.P. KE-10 at Peace ! :( :D :lolcry: :lolcry: * kneels on one knee & says a prayer *

Oh well Mikey. It will probably finish up in Holland or somewhere remote. Finland ? :)

You are spot on Jamie. The clutch driven plate comes in 19 spline (4speed) & 21 spline for the mid to later (5speed) The pressure plates are pretty much interchangeable, except for some of the very early 2K & 3K motors, which had different mounting bolt spacings for the pressure plate. :)

No Fook ! I don't think it drifts. It just goes in a straight line: . . . . . very swiftly. With those big lower front defectors, it suggests to me, it might just land on water very easily. I'm just fascinated by the pictures & the amount of engineering that has gone into it. Anyway, I'm off to the garage now, "to sharpen the mower blades" and clean up & see if I can't come acoss a jet engine, I'd forgotten I had. :)

For those of you who might not have seen this link in Toymods, to a guy in the USA who has too much money or something . . . . You won't believe this ! I love the bit about it being street legal. I'd love to see the face of one our boys in blue, as I pass him on the Logan motorway @ say 150 clicks. Jet Powered MR-2 Toyota on eBay :)
