WFCO are NOT the best converter.....marginal is more like it
1st off...check/verify that when you have 120V AC power the converter is getting AC input. (tripped Circuit breaker/loose wiring etc)
IF AC input then disconnect battery cables and measure DC output at converter DC POS and NEG terminals---on face on converter by the rack of fuses.
With AC power input the DC power out should be 13.2V DC MINIMUM. Any lower converter failing
Lots of posts but I'd say if you got 10 years from a WFCO converter, you did good. Time to upgrade to a Progressive Dynamics.
Bottom line is WFCO is cheap so that is what OEM's use
