2002 Saturn L100 Repair Question
What does battery dashboard warning light mean?
Did you have the new alternator tested before installing it?Also have you seen what the voltage is at the battery with the engine running and the battery light on?
Put the tester on today. Battery 12.5 and alternator 15.9. Charging system warning light still on. Checked all fuses-OK. Will change drivebelt due to mileage-original drivebelt-but don't know how to check tensioner. Once new drivebelt on, i don't know what to do next.
You just kinda feel the tension on the tenisoner using the breaker bar.So the car idling the voltage at the battery reads 15.9 volts thats too high.Did you have the alternator tested before you left the store?Also was the battery light on as soon as you put thr new one on?Or was it a few days that it starting coming on after you changed it?Why did you change it?You just have a bad voltage regulator in the new alternator.
15.9 alternator with car/lights on. With car off battery 12.5. As soon as I ran the car, the check light came on. I think I made a mistake changing it.
So you never had the new alternator tested before leaving the store?I always have them test the alternators starters etc that way i know the new part is atleast good when i installed it.So you have a bad new alternator or another issue.So you said you think you made a mistake when you put it in.Do you know what you did wrong?
I took alternator back to store and got a new one. Installed new belt as well. I didn't mean I installed incorrectly, only that I didn't test before installing. According to Auto Zone, they can't test this alternator because they can't clamp to test. Charging system warning light still on.
So are still reading the high 15 volts?
This week the testing showed a bad battery. replaced battery. Meter now reads 12.9 off and 14-4 with engine running. Charging light still on, but goes off when alternator is unplugged(non power pigtail). About the only thing I haven't changed is the plug.
The voltage is good do you have multimeter you can check ohms etc with?Sounds like a issue with the wiring possibly.
I'm using the multimeter at Auto zone. Check what about ohms?
