Question about 1999 Oldsmobile Silhouette
The battery light on my minivan keeps popping on from time to time. The battery indicator light will come on and then immediately the van will lose power. I then have to turn off the A/C and Radio to get the light to turn off. The first time it happened the van actually died. So we replaced the alternator. Then a few weeks later the van died again and found out that the alternator we just replaced was burnt out. We exchanged for another one and replaced it again. This did not solve the problem. The battery was not taking the charge after hooking it up over night. So we replaced the battery. Everything has been good up until last week when my battery light came on again when I had the A/C running. I parked turned the car off and let it sit for a few minutes then turned it back on with the A/C off. What is sucking the battery life from the van?
I am going to hazard a guess that you have a bad ground connection somewhere in the charging circuit . Check ALL your grounds on the body, engine and frame for looseness or corrosion. It may be intermittent depending on temp or vibration some double check everything twice. Bad grounds can do weird things sometimes.

Check all your ground wires for corrosion and tightness .

Check all the connectors in your charging circuitry.
Check if no cable is worn and thus gives directly to the body ( or engine )
Had a similar problem in a Patrol. The charge lead from the alternator to the main circuitry was worn against a bolthead and gave directly to the body at moments...
