Problem Inverter question

[Kevin D Pem]

The fan should only run with a fair load.

After consulting with a repair tech and trying a few tests, it seems as if the inverter has given up the ghost. Now it won't even pass power to the coach. To simplify installation, I ordered another Magnum ($$$). At least the new one is compatible with Lithium for the next battery change out. Now, to try to get the old one out is my next adventure....

MS2812-L-U. Newer model that will work with Lithium, or so I'm told.

Let me know if you want help.

Thanks Buddy, I just got the old one out and waiting for the new replacement. What a PITA it was to pull it out from up between the frame rails. In the end, gravity helped, but I ended up with a bloody arm.

Got the new inverter delivered yesterday and installed it this morning. (kudos to Peter at Inverter supply in Royal Palm Beach. Fast shipping and comparable prices) I stuck with Magnum because it was the easiest way without changing wiring or control panel, and since the original lasted 10 years, I'm happy with that life span. I will say, if you plan on doing this yourself, have some assistance getting this thing back up on the platform. I blocked it up off the floor, heavy end down, adding 2x4s on each end, one at a time, until I got it close to being able to tip it over to its mount. Took about 3 hrs install (lots of double checking on the wiring) but I'm delighted to say it's working perfectly, thank God!

BTW, here's a pic of the old one. The fans are actually good, which surprised me. The "heavy" end is the one with the big chunk of transformer...
