Anyone ever have any weird charging issues? my voltmeter goes wacky sometimes after a cold start, but not always. I don't hear the grid heater relay clicking so it's not that loading the system down, this is a "newer" battery from my mud truck since the one that was in the truck recently had a cell die.


this is what i'm talkin bout.

 

Looks like the grid heater is cycling to me.

 

thats the way my 91 does.

 

same here grid heater i dont hear my relay clicking but it definetly is workin

 

ok, thanks for the input so fast!

I guess it threw me off because I didn't hear the relay, and it's done that mid summer when it was 80 out.. not all the time, just sometimes.

I've had more wtf moments with this truck...... guess thats what owning a dodge is all about
