Inverter blows fuse on 2109S
Has anyone had this problem?
We just purchased a new Rockwood 2109S.
I have an inverter (converts 12v DC to 110v AC), a small Xantrex, 150 watt output, 15 amp current draw.
It has worked fine on my previous trailer when we had the occasional need for it.
Since, for some odd reason, Forest River spec'd a 110v only TV I thought I would plug in the inverter to run the TV for the times when we are dry camping.
Yesterday I plugged the inverter into the 12v socket provided in our trailer and it promptly blew the 15 amp fuse in the trailer power panel.
I thought maybe there was a short in the inverter's cigarette lighter plug but everything was fine.
I replaced the fuse and it happened again. Note that I had the switch on the inverter in the off position each time so there was no load being presented to the circuit.
I then took the inverter over to my truck and plugged it in both 12v sockets and it worked fine.
I plugged a small portable 12v fan into the trailer socket and that worked fine also.
I increased the fuse size to 20 amp and then 25 amp and each time I plugged in the inverter it blew the fuse.
So I feel I've exhausted all possibilities and I'm left scratching my head.
Why did the inverter work fine in our old RV, continues to work fine in any other 12v socket, but blows the fuse in the Rockwood?
