The solar controller is no longer that one I have a bougeRv 40a mppt controller the breaker is being changed as well but im pretty sure it's not the cheap powMR or the cheap breaker that's causing my issues
Lol thanks guy's I'm still trying to figure it out I will change the breaker. I just purchased an adjustable buck converter I might be able to add it as just a dedicated 12v line for the heater I have to figure this out its driving me crazy
I just tested the voltage just after the buck converter under load with the diesel heater and it was holding a constant 12.23v but the heater still drops out in a few minutes in
