Title: Fuses???
Post by: Matts-gen2 on August 23, 2007, 09:34:25 AM
I broke my alternator while it was on the car, so quickly removed it to see if it could be fixed, i was loosening the nut with the wire that goes on the condensor terminal ( the brown plastic bit ).

And due to my ( oh s**t ive broke the alternator ) state of mind i forgot to disconect the battery, doh!!!

I sparked the rachet off on the top of the engine, basically earthed out i pressume.

Now, ive replaced the alternator, added a twin pulley, 3 new belts, connected everything back up.

Tried to start it, nothing.

It has got a piranha immobiliser ( which doesnt seem to be in operation, used to work ), but the ignition wont do anything.

The central locking works, and stereo turns on.

Is there any obvious fuse that ive blown, or is it just check everything, does anyone know if the immobiliser would have a in-line fuse or box??

Do you still have bat voltage on the terminal on the Alt?
If not you may have blown the 100A ? (bolt in Fuse) on the fuse box (engine bay)

Right found the culprit!

It is the main fuse thats blown, but its an 80A not a 100A.

I presume an 80A is the correct one for it anyway, the cars a 1989, so may have a crossover one???

Anyway has anyone local to Essex got a spare 80A fuse?

Needed for tommorow if possible?

Does that mean if it a 70Amp alternator, you need an 80Amp fuse?

Just read your other post.

That should run better with that alt now?

Did you sort your water leak after your strip run?

I was the one with the red egi.

Yeah, i did write off the alternator trying to get the single pulley off tho, trying to keep the fins still, screwdriver, ratchet, broke fins.

Ive learnt my lesson, use a rattle gun in the future.

Power steering belt seems good, alternator belts maybe tiny bit loose.

How do you get them tight, i used the flat end of a crow bar to lever the alt up on its adjuster slot.  Theres no other way really is there.

Il re-check belts after 500-1000 miles, hopefuly  wont be screetching  down the strip in October!

Just phoned local (independant) shop, who reckons hes got a fuse for it there.

Bonus! I havent drove it for a week, wana get out for the weekend if the weather is good, sunday drive and all that.  

Hoping its gona run bit better with the dual pulley aswell.
