What does the charger do when on shore power? There is always the possibility that the old Magnetec charger is having problems also.
Since you don't have a frequency meter you can use a digital clock to check frequency but it might take an hour or so to show an error. A basic digital clock uses 60 Hz power as the timer. If the frequency is too high the clock will gain time. The clock on the coach microwave oven would work for this test. What I can't remember is how much error a 1 Hz change will cause.
