Battery problem

Generator on. Panel shows an error.  battery is not charging. Yes, they have water.  Yes, they are only a year old.   What else can I check?  Grrrrrrrrr!

Janey. (Sick to death of battery problems)

If 120V going into charger/inverter (assuming) from gen set should be 13.5V-14.5V volts going into the battery.  Have you
put a meter on the battery and the output leads of the charger?  Sort of backtracking from batteries to the source
to eliminate any wiring, charger, breaker issues.  A resting battery would read 12.0V to 12.6V depending on the state of charge before starting charging process.

Well - guess what!  The E02 message is gone. All is well.  Batteries are charged!  Magic?

Janey... Glad for the magic moment with your battery problem.  The E02 code, I assume was from the inverter or Charger (Xantrex), whatever your coach is configured with.  This is what that trouble code means:

E02 High battery voltage
shutdown
(> 15.5 Vdc)
Inverting • Check for external charging sources, such
as an over voltage alternator, and
disconnect if necessary

As you can see, the cause was from an overvoltage condition.  Since everything is working now, we can only assume it's one of those electronic flukes that caused the problem, much like why we RE-boot our computers occasionally. 

Happy camping
