i bought an ammeter for my truck how do you hook its up i think its different than the voltmeter and i have no directions can some one help thanks?

You'll need to run some heavy gauge wire through the firewall into the cabin. Be very careful that it can't rub on anything. Power will have to go through the gauge for everything on the truck before distribution.

Yes the ammeter has to be connected in series to work. There should also be a indicator lamp that connects to your dash lights.

on the gauge theres a + and a - and the a ACC.? where do they go?

the big terminal on the alternator (bat) goes to the ampmeter and the other terminal on the ampmeter goes to the + terminal on the battery (or battery cable at the starter). If you have a 12 volt generator, the A terminal on the generator goes to the A or G terminal on the voltage regulator. The "B" terminal on the voltage regulator goes to the amp meter, and the other side goes boack to the battery. The amp meter is always between the battery and the charging units voltage regulator


Hope that helps
