Ammeter discharge with key off
Any ideas why my ammeter shows a strong discharge when I turn off the engine? It shows a strong charge when the car is running. Right now, I'm disconnecting the battery cable when I shut the car off. Later, when I connect the battery cable again, it is normal at zero (not showing discharge) and starts up fine. So the discharge seems short-lived.
Thanks. |

Re: Ammeter discharge with key off
I would also agree sounds like a stuck cutout. That will kill the battery in short order. ken ct.

Re: Ammeter discharge with key off
I agree with tapping the cut out when the problem shows up, or a wiring disconnect there if tapping doesn't do it. "BUT" I have had the same problem and found it to be the reproduction ammeter needle sticking!! Tap the ammeter and maybe watch it go back to zero.

We had the same problem with my Son-in-law's 28 Sedan. Turns out that the Light Switch was grounded. It was a cheap Repo switch. I took the switch apart and cleared the groung in the contact ring.
