I pulled my car out of storage a few days ago, i fired her up and ran her about 300 miles to get the cob webs out of her over the next couple of days. Then the other day i took her for another cruise and when i parked her i went to shut of the ignition and poof everything went dead, i know this because i have twin electric fans with a manual on off switch and i always kill the ignition then shut off the fans, but this time the fans went dead as i shut the ignition off. The battery has plenty of power, the altenator is new, the voltage regulator is new, i got under her and shorted across the starter and the starter motor would run, i was wondering it seems like i have blown a main fuse, or lost my ground or the solenoid on the starter is gone, the only thing i seem to have power to is the headlights, i have no power to anything else. Is there a main fuse? If the solenoid was shot, would it affect many systems in the car? I was thinking of replacing the complete starter and solenoid and see what happens but of course i don't really like to just replace parts for nothing, one question i got is on the solenoid i know there is two wires your main and the ignition wire, would there also be a ground wire, and if there was and say it broke would it effect multiple systems, its strange to me that my fans don't work and wipers and accessories but not like i have many to begin with. I know just before this all happenned i a couple of times had to stop and restart my fans cause i was getting a buzzing noise from either the firewall or under the dash, kinda from the location of the voltage regulator, although i was getting correct voltage all the time. Any suggestions you may have let me know i really want the beast back on the road..........
 
Hello some older cars had a fuse able link on the pos. battery. Check between the there might be two leads at the BATTERY one goes to the starter the other goes to a power acc. take a test light and check to each one will not have power that will be the one where the fuse able link will be located GM cars had two cables one fuse able replace the pos battery lead.
 
Sounds like you burned up your voltage regulator. It may have taken a fusible link with it. The fusible links are fat wires coming off of the positive terminal that act like fuses. Best bet is to change out the voltage regulator and check all your main wiring very carefully, including your ignition switch.

No, a stuck starter solenoid won't cause this kind of problem.
