Default Re: Batteries completely discharging

Rivco:

I read; you've tested the generator cutout as per Les Andrews blue book. My compliments, the blue book is my favorite source for electrical problem diagnosis.

If the safety fuse (by the starter stud) is installed, and the test light between the removed battery cable end and the battery post is lighting up steadily, it is a draw, not a 'short' that you are looking for. This draw may or may not show up on the ammeter depending on where the problem is and / or how your car is wired. (with or without the Nov. 1929 Service bulletin page 390 is or isn't applied)

X2 on post 5 and 10. Your dash light, a brake light or any other accessory not original to the car may be on.
