1938 plymouth truck PT57 amp gauge wiring

[Classic Moose]

i have installed a new wiring harness all original and i can't find out which wires go to the positive and neg. terminals on the amp. gauge. 

dose anyone know which side of the gauge (+ or -) the BATT trem on the voltage reg goes to and which the negative battery hooks up to?

thanks,

bruce moose

Not to be a smarty pants, but ya got a 50/50 shot of hooking it up correctly . . . otherwise, it'll just be backwards and show discharge on the gauge when the regulator kicks over to let the generator charge the battery, shouldn't be able to let any smoke out that way

it makes no real difference if you get it wrong..the gauge will only read backward....so, if not right when you do the initial wiring...just reverse the leads....

Thanks for the tips. I did get it finally.

Where did you purchase your wiring kit from Classic Moose?  I will need to do my wiring someday, and I am hoping to find an OEM application.

Is this one of the kinda odd amp gauges that has the fuse on it? If so you've got an in and out as mentioned above along with a third mount I believe for accessories.

Yes I do have the amp gauge with the fuse thus 3 terminals to connect to. Appears if too many electrical draws are connected to the fuse side the gauge pegs out .

A little bit pricey, but a nice original looking wiring harness comes from Rhode Island Wiring.
