I have a Multiplus Compact 12/2000/80-50 120V that has been working perfectly for over 1 year and all of the sudden it won't produce 120 volt.
My batteries are full and the cables suppling power to the inverter are reading 13+ volts on the inverter posts. It has power for sure. Also, the fuse for the inverter is not blown AND I swapped in a new one just to be sure.
I opened up the case and took a look at the interior and have two main questions.
1. How many fuses does this have and where are they?
I noticed a fuse but am not sure what it goes to. I did try and swap it out with another 20amp fuse but that didn't do anything.
2. What is this red, internal LED telling me?
It says "ALARM" but this light isn't visible with the front on the unit.
Here is a closer view
Lastly - When I started troubleshooting the unit I did notice that the sheathing of my romex may have knocked off the protective cover of the fusebox for the power supply to the inverter. I'm guessing these might have rubbed together... Not sure if that actually happened, but if it did I'm wondering if this is what is causing the inverter to malfunction.
HELP! I CAN'T MAKE COFFEE!!!!!!
