Depends on the wiring of your RV. Some RV's are 30 amp, some are 50 amp. The 50 amp RV will use two separate circuits. Using two separate circuits in this circumstance is disastrous. But you shouldn't need more than 20 amps for your AC. 2500 watts is only about 10 amps.
Check with a voltmeter a fully charged battery should read approx. 12.8 volts without engine running with engine running at approx. 2500 rpm reading should be approx. 13.8-14.2 volts
A fully charged battery should read approx. 12.8 V without engine running With engine running should read Approx. 13.8-14.2 Volts
A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
Check with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running When running reading should be approx. 13.8-14.2 volts
Bad alternator? A fully charged battery should read approx. 12.8 without engine running With engine running should read approx. 13.8-14.2 volts
Alternator not charging battery sufficiently? Check with a voltmeter: A fully charged battery should read approx. 12.8 volts without engine running. With engine running should read approx. 13.8-14.2 volts
You can hear it running. Unplug the fridge, then wait approx 1 minute and plug it back in; you should hear it kick on.
Approx 18.56 mph.
Check alternator output with a voltmeter A fully charged battery should read approx. 12.8 volts without engine running Should read approx. 13.8-14.2 with engine running
Perhaps alternator is not charging battery properly - check with a voltmeter a fully charged battery should read approx. 12.8 volts without engine running with engine running reading should be approx. 13.8-14.2 volts
Bad alternator- not charging battery enough to keep vehicle running check with a volt meter A fully charged battery should read approx. 12.8 volts without engine running With engine running should read approx. 13.8-14.2 volts
Weak battery not holding a full charge or alternator not supplying a suffient charge to the battery - check with a voltmeter A fully charged battery should read approx. 12.8 without engine running Approx. 13.8-14.2 with engine running
