Thread: isuzu Alternator

Hey all

my rangie (4BD1T) was charging intermittently and i discovered that it was the alternator. a replacement new on was going to cost about the same as having the old one fixed, so i ordered a new one through work (OEX HXA005). It arrived today and i put it in with little difficulty apart from wiring.

Both are internal reg types however the new one is a 4 pin compared to the 2 pin old one. Anyway, to cut a long story short i misread the plug diagram as looking at the plug and not looking at the socket as it was meant to depict. so I connected a few wires incorrectly and there was a bit of electrical smell and no charge.

what is the best way to check if it is the reg or actual alternator i have broken?

The signal wire and the ignition wires have 0V with ign off and ~12v with ign on.
The dash light wire has ~2v regardless of ign position.
and the last wire (stator) is unused.

any hints/help would be much appreciated.

Cheers

Cheers for the replies,
I ended up getting it tested by an auto elec as I ran out of time with the start of uni semester. It ended up being a faulty reg, my wiring was fine and my pride restored.

The manufacturers don't make a reg for it so I will just try and get cash back for the first alternator. I ended up just biting the bullet and getting a Mitsubishi type one which is in and charging beautifully.

There was a few days that I had $2 to my name as the whole exercise ended up costing around 800 and I am a poor student. hopefully get a lot of that back with the refund of the first alternator.

Cheers
