Howdy,
Battling inverter issues on my Fuzion Chrome 414. My unit has the residential fridge so we've got the red power inverter mounted in the front storage compartment from the factory (sorry I don't have the make/model).
When plugged in to shore power I get a single green light and it appears to be passing power through to the fridge outlet. But, no display, no fans kicking on, etc. like normal. I get the same result when the generator is running. However, the second we unplug or the turn the generator off, the inverter is dead and the fridge goes dark.
Thinking it's one of about 3 possibilities but hoping someone has encountered this before?
1 - fuse on the inverter is bad (will try this first)
2 - Internal batteries on the inverter are bad, but feels like I should still get a display when running on shore or generator power?
3 - inverter is toast after 18 months... That would be disappointing.

Any ideas?

Thanks in advance!
