greetings all,

ive got a 67 camaro that i run on the strip. i just changed out the alternator to a powermaster 100 amp. after changing out the alternator the battery
(3years old) lost its charge. i replaced it with an optima deep cycle 750cca battery. when i went to start the car 3 days later the new battery was dead. any ideas on what could be draining the battery? there is nothing hooked up to the battery other than the ignition and a fan. any ideas are appreciated.

thanks,

jamie

the new alternator is bad?

have the altenator tested

looks like you got a bad one.

As a side note, often when an item is drawling current, it will be noticeablely warm to the touch. This may not be totally definitive, but it is a quick check. When the car if off and has sat for awhile, like overnight, if something is warm, the only source to create warmth is electricity ...

Remove a battery cable and place a test light to complete the circuit. The light shining/glowing indicates current flow.

Now, pull fuses and disconnect electrical items till the light goes out. The last one pulled/unbolted is the culprit.

I had the same problem, found the "new" regulator bad. Replaced it and no more problems.

This test light trick has worked for me for over three decades. Simple and easy to do, it will point you to the source of the current drain.

have the starter checked...That was my problem..just like you the batt would died after a day or so.......
