starter wire

[34ford]

Hi,

Hoping some one can help me on this. What colour is the wire that gos to the starter motor? I have the Bat+ and from memory im sure the earth is connected to the engine but whats the colour of the other wire?
The engine is bolted in but i just can't get behind it to trace that wire.
Thanks.

Thanks Lex,
I read that before but couldn't find the colour of the wires. If only i paid more attention when i had the engine out.
Its in a hotrod, so space is limited and the engine is right up against the firewall.
If anyone has there 1UZ out could they look at the loom that runs to the starter. Thanks heaps

The starter wire on my crown motor is black, slightly heavier gauge than the sensor wires and has the year of manafacture printed on it
hope that helps

Thanks for that, ill go and have a look.
At this stage, i think i have it all wired, but when trying to start it, i can hear the starter relay click over and a small nosie from the starter. I'm going through to make sure i have all earths etc, but sounds like my starter might be stuffed.
thanks for your help

I should be the largest wire. Ground would be from the block.

34 Ford,

I'd be surprised if it's the starter. The half cut engines we get out here have very little K's on them so I would expect the starter to be fine. I've had three engines and all the starters are good.

If the solenoid clicks it means it isn't getting enouugh current/volts to let it crank.

Can be either a bad/dirty earth between the block and chassis or chassis and battery or a bad/dirty +ve connection at the battery.

If it's clicking you have the right solenoid wire. It is the heavy black (about 3mill in diameter) wire.

You could also just check the battery isn't in need of a charge. Silly things happen.

Thanks Zuffen,
I have charged the batt, but i'll try the batt out of the road car. At least i know that one works. I'll check all the earths, power tonight and see what happens.
Thanks again guys.

If all else fails feel the terminals on the battery cables and at any joints/earths right after you try starting the engine. You could have a high resistance joint between a cable and the terminal its crimped/soldered to it (this is the terminal of the cable). Very hard to find but not uncommon.

You could also try using a volt meter on the starter cable as close to the starter as you can get. To do this pierce the cable with the +ve probe and earth the -ve probe. This will allow you to see what voltage you have when you flick the starter. Any drop below 12v means the starter will work real hard if at all.

You do know the engines not seized?

Here is the wiring diagram for a lexus if thats any good to you.

The starter motors in this motor are very prone to failure.
Almost everyone I know who's done a conversion has had to pull it out and rebuild it.
Its nothing major, just some build up from sitting around, needs a good clean.

I tested mine while it was out of the car, fired fine.
But once it was trying to turn all pistons at full compression and a flywheel/clutch it pretty much failed.

If you haven't stripped and cleaned it already, I'd be looking at doing that.

But definately try first with a decent earth and power cable.

hi guys,
I agree with Peewee i was told the bearings freeze to the armature shaft if left for long periods, ie in the breakers yards, and then turn in the housing, it was suggested to remove the starter, free up the bearing etc and then locktite the bearing to the caseing.

Best Regards
Lambo

I think i found my problem........me. I really have no idea, electrics is really not my game. But i'll keep trying, don't like giving up.

What i thought was the starter relay clicking is actually the EFI relay clicking. Im still using the fuse box that come with the loom (The big black one). Altho i don't plan on using this i thought i could use this just to start it.
I have the ecu,ect all wired up using Kdogs diagrams (Thanks Kdog) but i think i have missed something else after that.
I have a few mates that know a little more then i do , so i'll get them around and see what ive done wrong.
I'll let you knw how it goes and post a few pics.
The motor has to come out for other reasons soon so i'll get the starter checked at the same time.

Mick,

It's going to cost you a few beers for your mates to help sort it out.

 

[34ford]

Zuffen.

The thought of giving away beer to mates made me have another go AND i got it to turn over. Didn't try and start it, as i just wanted to get some oil around the motor before firing, its been sitting for a while.
Have to to do some over time at work, so it might be a few days before i can get to it again.
But it all looks good and should have it fired in few days.
Will keep you posted

relay wiring

Sorry if this has been asked before on another thread.
I have been seacrhing but unable to find all info needed on which relays i need and how to wire them up. Crown, using standard ECU & ECT.
I have been able to find some info but as mentioned before wiring is not my best subject...... and when it comes to relays im lost all together.

[Zuffen]

Mick,

PM me an email address and I'll send you a write up on wiring the Crown without the trans ECT.

This will at least get the engine running. I can't help with the trans wiring as I haven't done one.

Mick,
get a bunch of 40A 5 pin relays from Repco, they are more than up to the challenge.
