14 Fuzion 395 Inverter Schematic Nightmare

Hello everyone! Had a power surge when plugged into shore power, (No GFCI - Lesson learned!) and blew my resistor right off the circuit board. Pulled the board to send to electronics shop and am stuck because they can't find the schematic. Called Keystone = NO LUCK, NO ANSWERS, NOT EVEN A RETURN CALL. I read the threads, searched online and am coming up empty handed. It'd be helpful to know the make and model of the inverter and perhaps contact the manufacturer but I can't seem to locate even that. Just trying to get the schematic of the board so the correct resistor can be installed and bench tested. Has anyone ran into this before and has discovered a resource to obtain this info?

Welcome to the forum!!

Sorry for your troubles. Do you mean inverter or CONVERTER?

Converter is common, and supplies 12V to trailer and charges battery(s) when plugged into shore power.

Inverter uses the battery(s) to produce 110VAC for things like refers and TV's.
From your description I would say it's the converter that took the hit. Good time to toss it and upgrade IMO AFTER you install a surge protector.

Airlift 5000 bags, Prodigy brake control, 5 gauges on the pillar.Used to tow a '97 Jayco 323RKS.

Power Surge, are you talking about your converter ??.Getting circuit board schematics for either a inverter or converter will not come from keystone, you will have contact the vendor. They may not provide that level of detail.

A surge protector/ems is highly recommended for your rig
