Alternator 2 wire to 1 wire

<< < (2/3) > >>

Reklaw:
OK, so the auto electrician installed the alternator, leaving the ignition lamp wire off (cause there was no place to connect it on the one wire alternator I suppose) but you think the alternator is charging OK. So the real issue is with the immobiliser. Is the immobiliser a function of an alarm, a Rhino or similar, or some stand allone unit? Can't the auto electrician fix this, or is the problem getting the car to him because it keeps on cutting out?

mick:
yes the car starts ok, then it starts cutting out because the immoboliser kick in, hazard lights etc etc.

its a vision vae 315-950.

I believe the thing must be wired into the the ignition and since i disconnected the ignition light wire the car does not think its being started. My elec is not an alarm expert and without a diagram I am lost. Autobarn fit the alarm originally I will contact them tommorrow I think

Thanks

Hi mick
If you have joined the two wires together at alternator ( brown - red )this is where it is causing you grief the alternator lite has a pos on it when ignition is on (pink wire)the light comes on when a ground occurrs at  alternator so you have put a positve  onto the negative side of warning lite which would then feed back thru warning lite & then upset alarm it thinks it is getting hotwired. Disconnect the brown wire at alternator & see how you go .

I got that wrong earlier. We did not join the 2 wires I left the ignition wire disconnected. I called the alarm supplier and they confirmed that the alarm is connected to the disconnected wire so the alarm is auto locking after I start up. They are sending a diagram to help me re wire it.

Hello Mick,
I am just curious to know prior to changing the alternator over what light would light up on the dash when the ignition was turned on (other then the seat belt light)?
