We have 110 volts .coming into the coach but electric is only running off the inverter draining our batteries. Help
Welcome.
How have you verified that 120 VAC is actually into the coach?
Are you plugged into 15, 30 or 50 amp outlet. And, assume you have verified power at the outlet.
Typical electrical power path (things to check):
A - Check for good 120 VAC shore power at outlet (breaker not tripped)
B - Check for good 120 VAC power at input side and output side of the Automatic Transfer Switch (ATS).
C - Check inverter/charger for proper operation. The internal transfer switch should automatically pass through 120 VAC shore power.
If you still have the black heart inverter try smacking on with a wooden object on the front where the on off switch is also make sure that the breaker for the charger isn't tripped.
If you have an EMS (like a Progressive unit) and shore voltage is low, it won't let power pass. It would display an error in that case. Just throwing that out there.
What does shore voltage measure at the power pole?
What is the actual voltage as measured on the input side of the main transfer switch? If you have good voltage at the power pole but none on the input side of the transfer switch, suspect the shore cord or shoreline reel (if you have the latter).
If you have good voltage on the input of the transfer switch but no output, one of the relays in the transfer switch could be bad.
