Everything worked inside the coach as we setup for the night. The heater was running as it was about 15F degrees outside. Hot water and lights in the coach worked fine.
About 2 hours after plugging into shore power, we noticed a smell of burning wires. At about midnight the smell was growing stronger so I unplugged the shore power and inspected the coach batteries. I found no obvious source of the smell but it went away after unplugging the shore power. None of the breakers were tripped and the coach batteries are new and full of fluid.
I'm reluctant to plug in again until I know what the problem is.
Any suggestions on a diagnosis would be appreciated.
Pull your converter out and see if anyting "looks" burnt or looks like it got hot. Make sure the shore power cord is tightly secured to the lugs on the converter. Then, leaving the converter out, plug into shore power and keep an eye on the converter, especially the cooling fan. If the converter starts getting hot and the fan doesn't "kick in" and you "START" smelling the odor again, pull the plug and get the converter checked.
