Default Ignition relay

Hi all,

been wiring the engine today so hopefully all correct (cheers for the diagrams Ash).
After a few initial problems I managed to turn the engine - positive and neg connected and a live feed from the battery (in place of the ignition switch).

Problem being when i connect the ignition feed up and turn the ignition nothing happens. Looking at the relay - seems i've been a bit heavy handed when reducing the loom (removing excess) and I think the relay is kaput!

Will bypassing the relay and putting in a starter button (but still retaining the ignition switch for IVA) have any long term effects??

haha, Ive done exactly that, and cut too much off the loom, and now there's only 1 wire left on the ignition relay , i havnt thought about what im going to do about, it, but for the time being, im just going to try and get the engine running.

I had my concerns when I did it (obviously i didn't know what it supplied, just thought it was one of those i was trying to remove).

Just been out and shorted the relay terminals, tried the ignition and it turned with no overheating,sparks etc.

So I can't see why i cannot just substitute for a push button (heavy duty of course). We'll see, i'll standby to be corrected.

Wonder what else 've cut out??????????

Theres no relay for the starter.

Except on later cars where it was an imobaliser relay.

Book says there is, fuse box as one, tested and all wires (ones left) connect with the ignition switch, battery and start solenoid.

Tested relay - no readings.

Its a J plate, did have immobiliser - removed it.

What relay are you looking at, if it's XII then that's the Imobaliser/ Auto Inhibit relay.

This was not present on pre-90 none automatic cars and uses a jumper bar to short terminals 86 and 87 in the relay position.

You can either hunt in the scrappy for one of the jumper bars, or connect the terminals with a flying lead. Or connect them via a conceled kill switch for added theft prevention.

TT,

not wanting to question ur knowledge but the book does say ignition relay.

I removed the hybrid system and the immobiliser (after market one).

Was thinking of a starter button but the kill switch sounds better then I can hide it.

I,ve used a kill switch ( red key thingy ),

it can also be explained that it is part of the required second anti theft device for IVA.

cheers

Right when you say you turn the key and nothing happens what so you mean?

The ignition relay is for the IGNITION fed systems and not for the starter.
