Hey guys. Just curious do any of you have any problems with voltage?? I noticed my car acting funny and so I put a voltage meter in it and it shows that the voltage drops down to 12.6 volts when you come to a stop. If you turn on the lights or put any kind of a load on the alternator the voltage jumps back up to 14.1 and is fine till I come to the next light. The alternator tests fine so I am not sure what to do??? Anybody have an issue like this???

 

battery load test?
How old is the battery?
