Inverter function 90SP36

[Chuck Wheeler]

Chuck,

Inverters also require more current to start than when running. Most of the better ones have a circuit that prevents the inverter from running the batteries two low. If the resting terminal voltage of the batteries is OK connect a voltmeter across the input to the inverter and watch it as you turn the inverter on. If you see a significant drop in voltage you probably have a poor connection between the inverter and the battery and this is causing the inverter to shutdown. The alternator is providing just enough extra oomph to get past the starting current. If you have separate starting batteries and the house batteries are old check the terminal voltage when the inverter is turned on. If you see a drop at the terminals it is time for new batteries if all the connections are in good condition. If you have a infrared heat sensor point it at the battery terminals. If they are warmer that the surrounding batteryyou have a poor battery connection.

The inverter on my coach will not kick in unless I start
the engine momentarily (I have previously reset it). After
starting the engine I can turn it off and the inverter stays on.
