In reply to Robert hinglebine. I don't know. You will probably need some electrical diag to figure out why the alternator can't keep up.

In reply to Thandanani. It's not a great idea to remove the battery while the car is running, as you run the risk of damaging some of the sensitive electronics in your vehicle. Perhaps there's an underlying issue with the alternator, or the alternator isn't able to support the vehicle at full load without the battery.

Hi, me too I have changed the voltage regulator on my car because it was faulty due to the short of alternator brushes. Now it is working fine but when I’m removing negative terminal of a battery the car just stop running, I wonder why?

Hi I have a BMW318i e46 2003 model station wagon. When I buy the car in 2018 at has an valeo alternator on the car. After 5 months my battery light went on a Sunday afternoon. I went to work on the Monday I when I arrived home the evening when I reach the drive way the car just switch off. I get someone to check it out and found that the regulator was faulty. I bought a regulator but still it did not want to charge the battery then we found out that the regulator is 12volt. I couldn’t found a 14volt regulator for the valeo. I bought a second hand bosch alternator that last 5 months and I bought I regulator for that that only last 6 months. I put back the valeo alternator and bought a truck battery and is driving now for 2months without the battery getting flat. But when I removed the the battery lead the positive or negative the car stop idle.

In reply to Gert. I'm not sure. Lots of vehicles house their voltage regulators in the ECU these days, so it is likely there.

In reply to jack. I have a Dodge Grand Caravan that sometimes gets sluggish, and a red spark appears on the instrument cluster. It gets clears by stopping the car and restarting it. From what I can determine, Dodge says this happens because of rust or corrosion in the Electronic Throttle Control circuits. (What I wouldn't give to get rid of Fly-By-Wire cars). Clean those circuits and it may clear up.

In reply to Shane. First figure out why the alternator isn't charging the battery. I think it may be best to take it to a shop to have them look at it.
