Earth sorted, but what about the +

Post Fri Apr 28, 2006 7:10 pm

OK,

I will try to explain best I can!
Im just finishing off the wiring on the M50, photo's later.

Basically, what I need to know is where the POS lead, (I think its POS because its "RED") goes?
Its the red lead that comes out of the bulkhead about three inches under the fusebox.

Cheers Guys

All reds to battery +.
E36 loom has a red or two that just pass through the wiring box - in one side and out the other connecting to nothing, and can be removed complete.
E34 loom, IIRC, doesn't have this wire.

Use the original E30 cable from battery+ to starter motor.

I havent touched the starter motor yet, seen a big fat earth coming from it with a battery terminal on the end??

So the red cable came off the battery plus? Its coming from my car! I get so confused, when I start it tomorrow, the bloody car will blow up!

You'll need a battery + to the starter motor. (Use the thick black E30 one), a feed from battery + to the fusebox, and a feed from battery + to your engine loom.

Does this mean more wiring??

Is that the red one coming from the bulkhead under the fusebox about CM thick with an O end?

Is that easy?

I know, its just Im scared!
Its like the time I re-built a car when I was 18, I didnt want to start it......

Took 3 hours for my to build up enough courage, then It fired first time.

It didnt start, All the wires must be right because the dash worked great!

Seems like a lake of fuel, Will get it done tomorrow....then sound clips.

Right, sorted....

But when I start the car, the starter motor glows red hot.

Now I know thats not right.

Im thinking, new starter motor or is there another problem?

Post Fri May 12, 2006 11:19 am

What part of the starter glows?

It looks like where the PoS connects.....

Post Fri May 12, 2006 5:17 pm

Is this happening while your keying it over or while its running?
If its while its running your starter is sticking and you should buy one off me

Post Fri May 12, 2006 5:33 pm

When keying it, havent had it running long because of the "NO" exhaust thing.

Post Fri May 12, 2006 5:36 pm

Possibly a bad connection then, Have you checked the tightness of the nut? Earth straps, mounting bolts etc?

Post Fri May 12, 2006 5:39 pm

The whole thing is turning now, the bit that the bolt sticks out of

when I tried to tighten the main nut for the POS, Have I broke it?

Just tried to start it again and now nothing?

Post Fri May 12, 2006 5:43 pm

Your solenoids fuckered then
Probably took a knock while engine swapping

Post Fri May 12, 2006 5:44 pm

Thought so!

Did you get me PM?

More likely a poor connection from the main battery cable in the first place, but it's well cooked now!
M20 starter has different teeth from M50 starter, depending on what flywheel you're using.

It was the starter that came with the engine!

I think I fooked it, was working fine.....then I changed the big black lead to the battery for a better one(Old one had a split in it) and I think I broke the starter then. Undoing bolt and the whole part rotated.
