what's the voltage when the car is off?
Could also be a battery issue if the battery is going bad and drawing too much. That's why I asked about the voltage when the car is off. If it's far below 12V, then I'd look to the battery first.If voltage at the battery is 12.5v at idle then you have a problem. Check voltage at the alternator to see if there is a drop between the alternator and the battery, if not then your alternator isn't putting out enough.
No, a short of any kind won't simply cause voltage drop. You would need a resistive (i guess inductive possibly too) load to lower the voltage that much.Someone stole my multimeter, ill go find one and test at the battery while the car is off. Im hoping its the battery and not the alternator, but i havent had trouble starting the car which seems strange if it is battery related.
could a short be causing this kind of an issue?
