Voltage issue, is my Alt. the problem?
Posted 28 July 2003 - 07:47 PM
When I first drove the car around, the voltage seemed a steady 13.8 or so, but seemed a tad high. There were no electrical issues so I didn't worry about it.
This morning, I start the car and at idle, it's putting out about 15 volts. At about 2,000 RPM it would peg to 18volts, and it'd stay at 18.
The only issue this caused was the stereo refusing to power up. I drove it to work and home just fine, but obviously I can't leave it like this.
I spoke with the previous owner, and he said the car had the same problem earlier, and he replaced the Alternator. That helped, he claims, but now the problem is back.
Do you guys think I just happened upon 2 bad alternators in a row, or is something else causing the problem?

That exact problem happened to my alternator, turned out the diodes were bad. So it was still charging, but it was way out of control.
Bench test it at a shop and that's what I bet you'll find.
