    Does anyone know why my APU would not kick on when my heat is running and it won't charge my batteries.

    Maybe the voltage isn't low enough, so no need to charge them. Mine is set to come on if it see the voltage is below 12.4

    There is an adjustment in the controller that sets the voltage level that will cause the engine to start. When I got new batteries last year (AGM glass mats) that have a different cell voltage, I had to have that adjustment changed to match the new cell voltage. Any ThermoKing dealer should be able to take care of that for you.

    About the Thermo King Apu Tripac, I am looking for a good link to a users manual but not finding one. Any suggestions?
