I installed a new wire harness from Howell ind and made my own dash.
now when I turn key on the alt light come on, good you would think?
But when I start the truck the light stays on, but the system is working putting out aprox 13.6-13.8 perfect in all respects except the only way to turn light out is to take a test light from pos side of batt and stick it in the brown wire on alt. Do I need to drop voltage coming from ignition to light?
have the same problem?
