Hello,
My alternator died of age and I bought a new one POWER SELECT 8188N. While I had it checked and confirmed to be working, it doesn't charge when installed in the car.
The dashboard light is off - no errors. Just the voltage is flat - showing battery's voltage. I can start the car and rev it up - doesn't help.
Checked the thermistor - it's OK. Checked all breakers - OK.
I searched the forum but couldn't find a case like this.
Any clues very much appreciated as I have difficulty fixing my Aurora here in Europe and wouldn't like to see it converted into razorblades because fo this problem...

I have an Odyssey Battery Dry Cell 78-PC1500 which I recommend to everybody (after having two stock AC Delcos).
I am able to drive >10km just on the battery so looks like it's quite good.

Well, I was going to suggest the thermistor but you checked that already. I can tell from your posts that you are pretty competent so I assume everything is connected correctly. My only thoughts on this are faulty wiring, or the alternator has failed you after installation.
Have you multimeter tested the alternator since installation? Or are you going off voltage on the DIC?

You cannot rule out the possibility that the new alternator is bad. It happened to me once on a car not comparable to an Aurora.....1972 442 W-25.

To my own surprise Rockauto accepted a return without any discussion even though I had the unit mounted on the car... seems like a probable and known case of a factory bad one. Still, a surprise.
I found that there is a check procedure described in the service manual which requires to keep car at 2500 RPMs for 30 seconds before measuring the voltage. Actually I haven’t tried that before so I’ll give it a try in a couple of hours.

Actually I haven’t tried that before so I’ll give it a try in a couple of hours. Unfortunately that didn't help. Ok, so your tests manually showed 12 volts at the new alternator? I have a wild, potentially unsafe idea about placing your battery under the car wired directly to your alternator and then cabled to the positive battery cable under the back seat. I figure if the new alternator charges then its time to analyze the wiring between there and the battery. These cars are two decades old. Is there a better test guys? |
