Need some advice from the electrical guys out there. We have a 2000 Discovery DP and were parked in a campground last night and all was well until this morning while eating breakfast. Suddenly the breaker box under the refrig started to chatter (click) real fast and real loud and the 120V lights got dim and were flashing along with the elec heater indicator light. Checked outside breaker and cord and voltage and all checked ok but when I turned the 30 amp shore power back on and waited for the time delay, it started to chatter again. Didn't have time to mess with it then so disconnected and hit the road hoping the problem was with the campground supply. Got to a different campground this PM and plugged in and after the delay relay kicked in the chatter started again. Everything works fine on gen but not on shore power. Inverter is working just fine so only thing not working is the 120V. I'm guessing it's the transfer switch gone bad but would like some opinions before tearing into it. Doesn't make a difference if I throw the main breaker so obviously the problem is upstream from the breakers and not a short in one of the recepts or lights so once again my conclusion is the transfer switch. What do you think? Anybody had a similar problem. Thanks for any help you can offer - Harv

Had he same problem on a 2000 Bounder. Changed the transfer switch and corrected the problem. The old switch was burned so bafdly it fell apart in my hand. Very lucky no fire.

Hardy212 - Thanks for the reply. Always good to have somebody confirm your thoughts. Where did you get your new switch? OEM only or does someone make an aftermarket? Thanks - Harv
BTW - saw your other post and would like to do the same to my rig so will be interested in hearing what others have done. My thoughts were to weld up a cage and install on full extension drawer guides. Should be enough room but haven't done any measuring yet. Good luck.

Follow the shore line into the rig, it should go into the transfer switch. With all power off/unplugged remove the cover from the transfer switch, should be 4 or 6 screws. Once the cover is removed you can mark the wires and remove them all three sets. Gen/shore in and switched power out. Remove the switch and take it apart. You may beable to clean the contacts with some emory cloth/or light sand paper. Clean it up good with some alcahol (Not Beer

) and let it dry out, you can also use canned or compressed air to help clean and dry. Put it all back togeather and see if that helps. From what you said, the shore power contacts may just be sticking. Sure hope this helps. Also depending on what you can see and reach you may not have to take it out to clean it. good luck and keep us posted.

So where is the transfer switch located for my 2005 Fleetwood Revolution ?
Thanks

Just got access to internet again so will let you all know what happeded with the transfer switch ordeal. My TS is under the refrig in the box with the breakers and fuses and is actually behind the breakers and fuses so had to remove them to get at things. Turns out two wires got squeezed together (maybe from factory) and finally wore through insulation and shorted out. Evidence of wire getting hot and insulation melting but very minor. Taped up bare spots, repositioned wires and all is well. Thanks for the help to those who did and take care. - Harv

Glad you got that fixed, Harv. That "evidence of wires getting hot" is kinda scary. Thanks for posting the followup; someone else might need that info sometime.
