Electrical problem
1975 Chevy Truck V8 Two Wheel Drive Automatic ????? miles
----------------------------------------------------------------
Hey, been a bit since I last visited and need some help on my battery drain problem on my '75 Chevy Scottsdale C10. Just wanted to inquire if a bad stater solenoid or possibly the starter would drain a new battery over a period of about 10 days. I've checked the alternator by disconnnecting the positive terminal on the battery while she's running and it stays alive. I'm not too sure if this is a good way or not but I'm having the alternator checked by a local shop. THANKS GUYS

Get a test light and disconnect the negative battery cable now put the light between the cable and battery negative post is the light On? If so start removing fuses one at a time -the fuse that turns off the light is the trouble circuit. Then break out the electrical wiring diagram.

In the event you removed all the fuses and the light is still On disconnect the alternator batt. feed and the connector-if this one turns off the light-the alternator has bad diodes.

Or you can use an ammeter which is the preffered method to check for an excessive parastic drain
