Can a bad starter keep your alternator and battery from charging?
YesFirst if the starter is bad the car will not start, if it will not start it can not charge the battery.If the starter will not work it can mean there is an electrical problem that will also prevent the alternator from charging the batteryThe starter itself CAN NOT CAUSE CHARGING PROBLEMS!The extra load on the battery can ruin the battery and that can ruin the alternator. But before that NO.
What else can act like an alternator I have a 87 Nissan Sentra and it's acting like the alternator lights going dimm etc. I've had it checked and they told me it's still good. So what else?
Sounds like you may have a bad ground. If you have changed the original battery cable ends, the chassie ground wire may not be attached or may have a bad connection. there should be a wire that attachs to the negative cable and goes to the chassis. sometimes they are bolted to the fender well. Another thing you may want to check is the ground wire from the engine block to the battery or chassis.
