1987 mustang t-top v8
ok this car is getting on my nerves...I just had a CAT installed and e-brake fixed and exhaust leak fixed and idling issue fixed and the car sounds great and all...when it STARTS
it has been running for the last 2 months perfectly fine!! I was driving it every 3 or so days
now keep in mind that before everything was done...I had a starting issue because of low voltage and something was draining the battery
just today (after 1 week of no driving) I went to the car to start it up (mind you I was late for work and I took the tops off and everything) and NADDA ZIP ZILTCH ...just a little click and then the alarm sounded really like it had seriously low voltage...
needless to say the car was unable to start and I had to jump into my '00 convertible
I need to find out why this is happening or I'm gonna go crazy!!

I'm having a hell of a time figuring out whats draining my battery as well, I made a thread about it and got some really good advice....

I've yet to go grab a new voltometer, mine was broken when I tried taking the advice!
Anyway, goodluck, let me know how it goes! maybe we've got the same problem?

you don't use a voltmeter..you use a ammeter or multimeter set to amps function and hook it in series with neg terminal and look for draw 25-50 milliamp is max safe draw spec at rest..if higher pull fuses until draw is gone and once you have identified circuit..grab a wiring diagram of all components tapped off that circuit and unplug components on that circuit until draw is gone and there you will have the prob component

Many times it is the voltage regulator in the alternator sticking on and draining the battery. It charges fine when running, but drainds the battery when off.
Might also be because you are on a Mustang forum with a Camaro in your sig[sm=bustedsign.gif]

haha ok ...so yesterday I went to advanced auto and had them play around with my old battery...the crank amps came out good...but after 30 minutes it tested bad....so guess what...3rd battery in the trash...and $77 later I have a new battery! hooked it up...car starts wonderfully again...so now anytime I shut the car off, I pop the hood and disconnect the negative lead
I pulled my whole house apart looking for my Multi-Meter...I CANNOT find it...
they are only 10 bucks but I might just borrow my Grandpa's lol
anyway I guess as soon as I get a MM I will start doing the fuse test!
