TriPac APU Alarm Codes

Do you know if the cooling fan is working?

 

I haven't seen it turn on. Its still freezing here at night. When apu is started warm it works normally without shutting off

 

Is the rad fan turning

 

No I havent seen it turn on

 

Can you turn it by hand?

 

Ill take off fan guard/shroud and try it.

 

Cooling fan is working. I have apu on and I see it running right now. I drove all day and now batteries are charged and apu is still running for no reason

 

The batteries are charged but what is the voltage output of the alternator? It wont shut off if the voltage is a bit low.

 

Ir won't shut off until I turn it off myself voltage is 14.2 -14.4

 

Voltage output is good ,check what the voltage at the sense connection on the strip terminal is.
