[RE-wrenches] Outback VFX input voltage cycling

[jay peltz]

Hi Ron,

Almost for sure its the genny.  What type and when was it last  
serviced and how many hours does it have?

if the voltage is going all over the place really quickly then its not  
connecting to the inverter at all.

So here is a test that might help.  Turn on a resistive load such as a  
floor heater ( size depends on the generator) to lock in the voltage.   
At this point if the voltage is constant, then the inverter might  
connect.

If this works, then the problem is most likely the genny, which case  
its needs some work.
