voltage leak/ alternator
Posted: Sun Oct 26, 2008 4:57 pm
Hi Folks,
I am chasing down a voltage leak.
S1/S2 1965: negative earth, alternator; fuse box replacing the old voltage regulator.
If I disconnect the negative battery feed and then measure the voltage from the negative feed to the negative battery post I read 12+ volts. There is no measured current running through the system.
As I was checking this out I disconnected the alternator from the system and the voltage from the negative lead to the battery post drop to 0.
I measured the voltage from the alternator lead to the alternator post and it reads 12+ volts.
Is this normal? If so why is the alternator circuit always closed?
Thanks-
Robb
