[QUOTE="WildJay90, post: 429488, member: 19550"] 1990 jeep wrangler 4.2L I am constantly getting a power draw of 3 miliamps on the battery from the alternator when the car is off. This is causing my battery to die in several days. I installed a new alternator thinking it was a bad diode, but still the same problem. If I unplug the voltage sensing line and ignition on input line plugged into the side of the alternator via an electrical adapter, the power draw goes away. Installed a new key ignition cylinder since mine was warn out and still same problem. I was considering placing an inline diode for one way power on either ignition line or voltage sensing line, unsure if that would fix the problem though. Any suggestions or input on this would be very helpful appreciated. I've looked alot online and cannot find someone with the same problem. Thanks in advance. [ATTACH=full]117514[/ATTACH] [/QUOTE]
