Little help/possible dumb question

Don't sweat it, the apu should keep the batteries charged as well. On some if not many of the the prime trucks, under the bunk the invertor will show the voltage that the apu is maintaining. Also many of the trucks will automatically shut off the interior lights when the voltage goes below a certain set point...... If your generator on the apu fails it should shut down and and throw a code on the controller........

 

Don't sweat it... the APU alternator charges the truck batteries. And you can always jump the truck from the reefer if you need to...

 

Just as a thought, I seem to remember some reefers (not for Prime, but another company) that had notices saying it would not support jumping a truck or charging batteries or something like that.

Maybe I'm thinking of something else? It's been over 18 months since I pulled a reefer.

 

Not on the Prime side. You'd better not call Road Assist and ask for someone to come out and jump you... unless the engine fell out of the bottom of the truck! Not with a working reefer engine and altenator; jumper cables are manditory equipment. That particular road service call is an expensive deduction from one's settlement.
