Re: Magnum MS 2812 Charger/Inverter Issue

Or only initially? Like I said, on mine, the hot relay shorted - essentially the hot leads from the shore power were connected to the hot leads from the generator power. When power is applied from the generator side, the delay is initiated then the neutral relay switches over to the generator neutral - everything is happy and works. When power is applied from the shore side, the delay is initiated then the neutral relay switches over to the generator neutral - now the hot and neutral is not matched and the problem occurs. All power is lost and the inverter thinks it's not connected to anything and turns on supplying power from the batteries. When it does this, the neutral relay drops back to shore neutral and now there is matched power in the hot and neutral supplies starting the cycle again. This may not be what is happening in your case, but if you notice the inverter/charger continually cycling, I bet it's something similar. If you know where your transfer switch is, open the cover and inspect the relays, you'll notice signs of overheating if this is your problem. One of the first things I did. All Transfer switch wiring is perfect and torque is as well. Power comes thru for non-inverter circuits every time on shore power. No issues with that.1KViews0likes0CommentsRe: Magnum MS 2812 Charger/Inverter Issue
rdhetrick wrote: Most likely the hot relay in the transfer switch. I just had to replace mine, very similar situation - when plugging into shore power, I had power for 30 seconds, then lost it. In my transfer switch, there is a 30 second delay in the neutral relay to give the generator to come up to speed before transferring the full load. The hot relay was shorted so when applying shore power, it triggered the 30 sec delay. During this delay, everything worked, but as soon as the neutral relay switched, shore power was lost. Replaced the relay and all is good now. Not sure if this is it or not as the power travels from shore connect, to transfer switch, to main panel, to Charger/inverter. If I have a transfer switch issue, why do I still get power to my non-inverter circuits such as washer/dryer and AIr Conditioners?1KViews0likes0CommentsRe: Magnum MS 2812 Charger/Inverter Issue
Update: All connections in the Surge Guard Transfer switch are good and torqued appropriately. Connection/hot/common/ground in main panel all good. Decided to bring the system online slowly by shutting off all incoming power (breakers) and main 50amp. Turned on the breakers 30 amp for the inverter and then one circuit and I got inverter power. Waited, and brought all inverter circuits up, and all was well. Next I turned all the circuits back off and then turned the 50amp back on at the pedestal. I have two 30 amp breakers labeled charge #1 and charge #2. I monitored my read outs on my Firefly /Vega Touch specific to the Magnum. When I turned on charger #1 it showed zero on the AC Input Volts. When I turned on charger #2, it initially showed AC input volts at 118, and that the charger had come on (float). After 45 seconds, it kicked off and my AC input showed 184 volts as it has in the past. I tested both 30 amp breakers on the meter and they both are good. I’m down to the shore power cord at this point, unless anybody has other ideas. Thanks again Scott1KViews0likes0CommentsRe: Magnum MS 2812 Charger/Inverter Issue

I really think this is some fantom reading because it’s the same each time and at different parks/pedestals. I don’t see this when the generator is running. I suppose the transfer switch on the park power side could be going bad and reading 181, but I’d assume it would vary in the numbers. Not sure.1KViews0likes0CommentsRe: Magnum MS 2812 Charger/Inverter Issue

It may be there is a failed neutral on the pedestal. 3 different parks now, all with good power both with and without the Bulldog. All voltage at each location was within range. Even watched it for fluctuation, boy that was fun.1KViews0likes0CommentsMagnum MS 2812 Charger/Inverter Issue
I have a 3 year old Coach with the above system. It’s monitored/controlled by a Firefly system, thus, no Magnum Energy Remote Controller which I hate. Inverter works going down the road, and Charger works if I happen to run the Generator. When I arrive at my destination, and plug into shore power, the system goes into Passthru mode, as it should, thus enabling charging/passthru power. Unfortunately it only stays on for 2 minutes before disabling all passthru power and charging. I can get it back on, if I shut off the pedestal, battery disconnects and then bring it back online. It will stay up and running if I disable the charge side, or the passthru side, but not both. When it does shut itself off, it goes from its standard 117-122 volts coming in, to showing 181 volts coming in. I’m sure this is a fantom reading, but what’s causing it. I have been at multiple parks, so different pedestals. I also use a Hughes Bulldog surge protector on Bluetooth so incoming power is not the issue. I have spoken with Firefly and Magnum and we’ve tried different things with little change. Connections are all good, I’ve tested the battery bank (individual batteries) and all good. We have also unplugged the bridge between the Firefly and Magnum, thus taking the Firefly out of play, and no change. Anybody else run across this type of problem.

Is it possible the Mount ring and screws are hidden by the inside upholstered door cover? The window is mounted and then the inside decorative vinyl door cover is then installed? Doug Thanks for the update. That was part of the issue, I did remove and completely expose the interior panel, no ring, no screws. Like I said, all the other frameless windows have exterior ring and screws, not this one.431Views0likes0CommentsRe: Fixed Frameless window removal/install

Doug Doug, you didn’t ask for the year and brand, it’s. 2019 American Coach Dream 45A, it’s in my profile as well. As far as the door manufacture goes, can’t find a thing. Finally got ahold of a mobile glass guy and he confirmed it’s glued. So there you go.432Views0likes0CommentsRe: Fixed Frameless window removal/install
dougrainer wrote: Who is the maker of the window? Kinro/LCI or some other brand? When you state frameless, there is NOT an inside retainer ring that uses screws? Years ago, National had a brand of windows that did not use inside retainer rings with screws. There is a "rope" around the inside rubber lip and if replacing the old window, you can cut out the rubber from the inside, which allows the outside glass to pull out. You install the new window and push from the outside, PULL the rope from the rubber inside retainer and it flops around the inside of the wall and pulls it snug. I have never seen a glued RV window other than a windshield in 42 years as a RV service Tech. Doug All the windows in the Coach are Frameless. All of the windows, with the exception of the one I’m replacing, have screws on the inside that are spaced 4-6” around the interior of the window. The RV manufacturer sent me a new window to replace the fogged one in the door. I ve removed the interior door panel and have good access to the rear, and there are no screws. The only manufacture name I can find is Paragon. Again, this window is in the lower half of the door, below the main window. If it’s not glued in, I have no idea how it’s held in or what used to hold it in place.433Views0likes0CommentsFixed Frameless window removal/install
I have a frameless door window that needs to be replaced on my Coach. Unlike all the others that have screws holding the frame, this one looks to be glued. This is not the main door window, it’s a smaller 24” x 12” window. I have the new one, just looking for guidance on putting it in. Thanks3.6KViews0likes10Comments
