Major Electrical Draw


Recommended Posts

New to the Board, with the first problem I've had with my 2003 996 Coupe that I've owned over a year.

After replacing my dead battery and then having the new battery drain completely within 2 days, I took my 996 to my mechanic. He ran the diagnostics and says the alternator is fine, but that there is a major electric drain in the system somewhere that he can't pinpont. I've heard of similar problems due to a short in the horn or the voltage regulator on the alternator.

Anyone experienced and fixed this problem?

Thanks much . . .

He must not know how to isolate an electrical fault...

You start by putting an amp meter is series and measure the draw (ignition off - no key). Then remove one fuse at a time and see which circuit affects the draw. Once you have found the circuit you then isolate which component is the problem.
