Good afternoon and welcome to JustAnswer!!!
What's going on with your heater grid?
The picture is your heater grid relays.. One side is to the battery and the other is to the heater grid... If you start it up what is the voltage at? Also after it's running the voltage will drop when the grid heater is active because it draws 90 amps and it cycles on and off... Is this what your experiencing?
