[RE-wrenches] OutBack 2024 troubleshooting question

[Ray Walters]

Seems like something wrong with the generator, if the Vac is going that 
low, or there's a loose connection eating voltage somewhere.
The Outback might still try to charge, but not be able to actually 
produce any amps with that low an input voltage.
Check the Vac at the genny when this is happening, and if its still good 
there, work towards the inverter looking for where those pesky missing 
volts are going.
Might be the input plug right at the genny, those take a beating and 
quit making good contact.  After a while they'll get so hot they melt.
