I have one of
these to let me know what is going on with my electric. You will be able to know what is happening at all times. I had my alternator fail going from Reno to Klamath falls. I found a Napa and put in a new alternator in the parking lot. My rig waas a 86 Chevy class C.
With a voltage monitor you will be able to see what happens when you turn on different accessories.
I agree with other posters that 63 amps is not enough. Mine I beleive was 90 amps. You can easily go above 120 amps as well. High amp alternators do not perform as well at idle as lower amp units and that is the caution for a higher amp unit.
When I had my class C I was checking amp usage of different accessories with my clamp meter and the headlights use up a lot with all the clearence lights ETC. I think it was pushing 40 with the headlights on.
I made it to Klamath falls, after the alternator failed, by running the gen and letting the converter assist the alternator to keep my volts up.
