I have a stock ammeter. I thought it must have a shunt somewhere. Any clue where it might be? I don't see a shunt on the dash panel and it must be shunted before the printed circuit portion. I just got the truck and I don't think it was working when I bought it. I did a conversion on the alternator and got rid of the external voltage regulator. Now I would like to be sure the ammeter is working. I can and will trace out the wires but if you guys know whats going on it would save me a lot of time. (lots of family stuff going on until Monday) Thanks
