So I've been having trouble with my 1992 Mustang LX hatchback. Battery gets completely drained within being off for 30min after a full charge. It drains COMPLETELY, the car doesn't even make the token "ding" when the key is turned to accessory.

What I have tried / done:

• Got a new battery, the old one was 4-5years old.
• Checked the drain with the car running and it all appears normal.
• Checked the drain with the car off and it spikes.
• Fully charged the battery, disconnected all fuses for electrical components and the next morning the battery was sucked dry again.

I'm really hoping I don't have a short somewhere, since it would probably take forever to track down. My dad thinks it might be the Voltage Regulator or the Starter Motor Relay/Solenoid. However, I have no disposable income at the moment so I cant just replace everything randomly.

Anybody have this happen to them before?

Thanks in advance.

do a parasitic draw test. it should tell you where your problem is. also do you have any aftermarket amps or subs? or anything aftermarket hooked up?

I had an aftermarket stereo installed but the first thing I did when the problem showed up was disconnect everything to be sure it wasnt the stereo.

I tried the drain tests and it was inconclusive. Even with no fuses in the car and all lights/doors double checked to make sure nothing is on, it still drains within 30min.

I hope this doesnt mean it's just some random short somewhere draining the battery. Because it would take forever to inspect the entire wire harness of the car. :\
