Battery Gauge Wiring

[Sergio]

There is nothing that limits voltage from batteries to key switch.

In some IQ carts, there is a diode in series with the Tow/run switch, so in those carts the key switch will be 0.7v less than actual pack positive voltage.

That can be thought of as a "feature" since the pack will always be a little better that You think it is.

You are connected to the "Hot Side", just move the "C" wire to other side ("Cold Side"), which is the one the blue wire is connected to.

If both sides are Hot all the time, You have other problems....

You were 100% correct. I had it connected to the "Hot Side" of the switch. Easy swap over and now it works properly. Thank you so much for your help.

I will soon be installing a Solenoid Dropout Harness on my 02, it will be interesting to see if it affects my meter reading. I am thinking it will. Right now the meter is dead on with the actual pack voltage...
