Wondering if any of our talented members have successfully performed their own repairs to a Freedom 458 Inverter. After numerous searches, I have found virtually no info on internal components, wiring diagrams etc. or repair procedures. The Owners Manual provides installation and operating instructions in addition to some troubleshooting procedures but no repair info other than taking the unit to a "Authorized Repair Center".
There has been a few cases mentioned where a interal fuse was replaced but the info was limited.
I'm fully aware that the manufacturer has taken great pains to keep repair info "proprietary". That said, I'm asking our very own "wizards" of any and all repair successes they've had with the 458 Inverter. Of special interest is the replacement of the internal main relay

Any pictures of the internal components of the inverter would also be greatly appreciated
