Im have some trouble with the old 'stang. Everytime i turn it off less than 15mins later the battery is completely dead... it has new battery, alternater, starter cylinoid, checked all the fuses, cant find anything obvious that would be doing it

Sounds like something is shorted out. Check your ignition switch and ignition module. From there check the starter solenoid on the fender making sure everything is hooked up properly. Recheck the alternator, if its an autozone alternator, it could be dead already. Check your wires and see if any of them "feel" hot.

Good luck on the track down.

It sound like a draw something is constantly hot ( getting power) make sure when you turn the ignition switch off everything is actually turning off.

I am going to go out on a limb and ask if your voltage regulator has been polarized? if you put in a new mechanical one as of late it needs to be in order to work. secondly is your key switch any good? I have seen old worn out key switchs do this. feel the switch body to see if its warm or hot. if so you most likely found the problem.

i didnt find anything unusually warm after half hour of cool down but the starter coil, which was hotter than the engine block.

are you saying the solinoid on the fender was hot?
if so you need new. they are nothing more then a relay with a high amp switch inside. if by chance one of the terminals got twisted in the body it will stick and do what its doing by drawing current. it will also make it hard to start after a while.

ok so if the coil is hot 30 minutes after you shut it off then you still may have a draw. you need to put a test light on it with the key out and see if its drawing.. most likely its wired wrong or you have a bad switch for your key.

I was just wondering something? does your stang still have point ignition? if so you may have the yellow bypass wire hooked wrong from the starter solinoid. it lets the ignition get a full 12 volts when started. if its wired wrong it may be hot all the time.

Just make sure you have no voltage at the coil after you shut it down. & when you do make sure it is below 10 volts when it is in the run position. The solenoid is prolly shorted. You need a resistor inline to the coil, It might blow up if it gets 12 volts.


Ask me how I know, when I blew the top off the 304 blaster when we got the wrong wore hooked up.
