I did the exact same thing but I used a thin piece of brown Perspex cut to size by a professional sign writer. There is nothing like the Monaco owner. 🙂🙂🙂🙂

Last Important snippet of advice on this topic. I discussed with Magnum Support why this "burn/short" might have happened. The wire is aluminum, this raised concerns for me because Al wire oxidizes and corrodes over time. They advised me that it is safe to replace this with copper. This was a simple fix IF you stick to Tom and Myron's advice and SWITCH everything off and wait 60 minutes to de-energize the entire inverter. Caveat: The responsibility falls on your head.

Hi Myron, I managed to get the circuit board out and there were no burn marks on the underside. It was a process of photographing everything to ensure it all returned the way it came out. I observed, (neophyte) that the spade connection must have been working its way loose for some and then at the appointed time and day 😆 burnt the connection where the wire and the spade connection joined. It had burnt it off. I put it all back together and it didn't work, because I forgot to push the pin connecters IN. Wow, after all that. The help I got from Tom and Myron was spectacular. It was their advice and knowledge that inspired me to “look under the hood”. It's working like a charm and my knowledge of inverters is greatly expanded. Thank you.

The help I got from Tom and Myron was absolutely spectacular. It was their advice and knowledge that gave me the inspiration to “look under the hood”. Thank you. I hope this solves it.

Spoke with a technician in Vancouver BC. Told me to switch the power OFF, disconnect the batteries AND wait 15 minutes, as Tom advised, then remove the housing cover and see if I could see anything. Well right there in front of me was a burnt crimp connector on the circuit board. Photo 3. Probably a loose connection and a Moisture issue. Going to replace the short red piece of wire (4.5") that goes from the circuit board plug to the power 'slot' as per Photo 4. Will get the correct materials in the AM. I hope this will fix the issue and I'll update you when this is done. Rick

Thank you Tom and Myron for your help. I'm taking this sick puppy to the Magnum People to get their techs to find the problem. It looks like it's better to replace it with a newer unit.

Went thru all the steps, and it looked like it was going to work but lasted about 15 seconds and failed. No pins tripped.

Thanks Tom. I'm busy sitting out the 60 minute "sin bin" penalty for tripping this thing with the kettle. 🙃🤣 I am pretty handy with all the electrical safety and I would NOT call your advice as OVERKILL. I'm good with more info than less. Maybe I need to get a reconditioned/new inverter? We never use the inverter because we never dry camp! Could I just rewire the two 15 amp lines OUT and connect to the a sub panel fed off the MB? As soon as I am through I will reply.

Thanks. I think that may be what my problem is but I'm going to work my way through Toms diagnostics first. I certainly keep active.

I did, but it still refuse to obey my commands. 🤣🤣

Thank you Tom. My head is spinning so tomorrow I’m going to diligently work through your masterpiece to ensure I do it justice. I’ll need a day or two get this done. Thank you Sir for the help.🙏🏻 Rick.

When I did a hard start on the unit it completely reset the unit and all the breakers had popped out. I reset them but it didn't fix my problem.

I've been through the recent thread on CGI inverter issues to no avail. My Magnum ME Series has has me trapped. I'll go ahead and explain the issue. We had this unit for 10 years never had electrical issue except for the odd overload trip. I switched my kettle on and it took the 120-volt power in the kitchen and washroom down. The microwave is still functional. The GFI didn't trip. All the main DB circuit breakers are functioning. The charger is working charging the batteries. The charger and inverter lights are on. No power in the kitchen or CGI washroom. If I switch the main Inverter Switch off, it defaults to inverting and the kitchen or CGI washroom all work BUT the charger does not light up or charge. Both the inverter and the charger work independently. The CHARGER works when the DB switch (labelled inverter) is ON but not the INVERTER. When I switch the DB switch (labelled inverter) OFF the CHARGER goes off (logical?) and the INVERTER works. Did VOM reading on all lines (16 volts) but will not work independently. Could you please advise me where to go from here? Rick

I have a problem with my Magnum ME Series that is similar to the issues being discussed here. Is it okay to piggyback here? I'll go ahead and explain the issue. We've had this MH for 10 years and there haven't been any issues or electrical work done on it. I switched my kettle on and it took the 120-volt power supplies in the kitchen and washroom out. The microwave is still functional. The GFI didn't trip. When I opened the inverter compartment it smelt "electrical". The inverter is blinking and still charging the batteries. There are 115 volts of power on the AC Output line but zero power on the Input line. It seems like the inverter is working but there is no power coming in. Can anybody give me some instructions on what to look for? Thank you in anticipation. Rick
