Connecting ammter/volt gauge (PIC)
 

i forgot whitch end of the wire goes to what terminal on the gauge :-[ is the wiring in the pic look right??

digital or dial guage?

if its digital it will read - instead of a positive #.

if its a dial it wont read at all.



just think of the path of the current, alternator doesnt draw in electricity does it? :P

its a cheapy dail, it was reading fine untill i pulled it out yesterday (car is back to stock) i just wanted to make sure :)

BTW remember my battery wasent holding charge, well i purchased a NEW red top altima, threw it in and it started up every time but, suddenly my "new" shitty alternator went out AGIAN! ::) replaced it with a bigger junkyard mitsubishi alternator ??? long story short, the battery was a defect i guess but fortunately the car runs cherry once agian 8) appreciate the help man :)

wait, why wouldent the dail read anything if it was hooked up backwords? just curious

negative flow cant be read on a postive guage

Re: Connecting ammter/volt gauge (PIC)
 

i think they are supposed to read slightly negative if everything is working correctly

ammeters read + and - flow, but are unsafe as most don't use 10-12 gauge wire.

Use a voltmeter instead, less chance of car fire.

FYI with a ammeter, ALL current goes thru the gauge, think about the losses involved.
