Dead Alternator = DTC that wont disappear!!
 

Hey guys, well my alternator died last week and now my boss just got me a aftermarket alternator.

It installed fine, regulator clipped on and it charges fine but now i get a DTC.
Alternator Circuit Low

I have erased a few times but it comes back on after 5secs or so which means it does erase but is still picking up a fault??

Any clues anyone?

Cheers Paul

Posting mainly for Search function, its seems that using an aftermarket alternator will cause the engine light to come on, i tried two different aftermarket alternators and both would not talk to the computer;
the first 1 from cooldrive been jayisec or something alike would charge all the time with engine light (which it isnt suppose to do, should only charge when it needs to if battery is fully charged)

the 2nd alternator i tried was al delco which would charge intermittently which it should but also did not talk to the computer as it lit up the engine light.

So in the end i just got a 2nd hand one from Jap Wholesale.

Hope this helps someone else later down the track!

how much was the 2nd hand one if you dont mind me asking?

Have you tried getting one through exchange, at least that way you'll get same type and 12month warranty.

Unsure what the price difference would be though.
