Ammeter terminals

[DollyDodge]

Hi all: Which is the positive terminal and which is the negative terminal on the ammeter. Seems I forgottowrite thatdown durning my disaasembly. Is t here a way to check that the polarization is corrct withou being cannected to the battery?

Well , if you get them wrong , you won't hurt anything . Then you can just reverse them . I usually test them using an old headlight and a battery and watch for the needle movement .

Could anyone tell me on the original amp gauge which terminal is negative and whichis positive? Is the terminal under the negative side if the guage + or -

I looked at the amp gauges I have in the box, and none of them were marked on the cardboard insulator.  However, one of the complete clusters that was pulled still had the red wire on the terminal on the right (directly behind the discharge side)...if that doesn't work out, swap terminals

Thanks, I understand about switching , I was trying to hook it all up correctly the first time . My amp gauge has an "I" on the discharge side on the cardboard.

"I" for ignition?.........

That is what I thought but it turned out not to be the case. I couldnt't stand it so I hooked the battery up and checked the polarity on the ammeter. I hooked it up as JB suggested above. I turned on the dome light and the wipers ( only thing cnnnected now) and the ammeter discharged. Not sure what the "I" is for. Anyway the wiper worked great and the dome light was bright!
