There is a 10 gauge wire attached to the starter solanoid on the battery cable side. Disconnect it and run it to the gauge, Run a another 10 gauge wire from the gauge to the solanoid. If the gauge reads backwards reverse the wires on the back of the gauge. The wire you disconnected at the solanoid is the battery feed wire. Now you will be running all the power through the gauge. Most after market wiring kits tell you not to do this but to run a volt meter instead.

You can go from the battery or from the starter Etc..., the part where they want you to be carefull is the INSULATION of the hot wires... They do not want you to short them out when installing the gauge because that could cause a fire and burn you and damage other items....

The reason you go through the ignition (Via the starter and other places) is so when the key is off there is no electrical drain on the system from the amp gauge.

I agree with the 406. I fully do not understand what FE is mentioning about the ingnition switch. In general after installation of a gauge, I set a Simpson V.O.M. onto the connections, just to make sure wires did not get grounded. Even weeks afterwards there should be zero to ground.

The ignition switch turns off the regulator and alternator. Thus, there normall would be zero flow anywhere on the thick gauge wire to ground or to battery. This is a new one on me, for have never heard of integrating the Ign. switch into the circuit. Nor, have I seen a diagram inclused inside the box of a new gauge on how to do this. Most times they mention, as does 406 to connect with two heavy gauge wires, and end.

Marla, remember to disconnect the negative battery cable while you are doing anything with the electrical system.

That wiring diagram is for a factory amp gauge. Won't work for a after market one.
