electrical problems
The 30 amp cord is pretty much a standard 110 with a funny plug on it
then? I knew that 220 was essentially two 110 hot wires but did not know that the 50 was similar. Having been in a RV store not long ago I noticed they had a featured item up near the check out a 50 amp plug with a distinct pull handle on it. I think they also had 30amp plugs similar. Didn't impress me at the time nearly as much as it does now. I don't have 50 amps into my coach but I learned something. I also did not realize the risk involved in the battery campartments. I was informed last year at the Maxton rally about that. I guess the low voltage stuff can be rather nasty as well. Perhaps some one will review and explain what the risk with the low voltage. Does make a rather nasty spark if you short the positive against the metal I know that. All kinds of ways a fellow can get hurt. I was up on the roof of my bird this morning and I was VERY careful. I remember seeing Don's X rays. I don't much like it up there but once a year I go up to check it over and see that all is well. Lets see. The thing can crush you, electrocute you, you can fall off, and then there is the road risk. I guess we can say it can get you coming and going as well as a couple ways in between.

I never gave it much thought, but now I wonder why that is there. It lends itself to be the point that is grabbed to pull the connector out, but that puts strain on the wires in the connector. Clearly I should grab the connector body to pull it out, not the wires. > > On 8/28/2008 at 8:31 PM Curt Sprenger wrote: > > >Don, > > > >Great Post...Everyone...All of us with our older coaches need to do what > >Don > >just did, check our coach connectors.
