The unit is 5 years old so I'm pretty sure I'm on my own.
Thanks for the input on patching the tank, especially the Water Weld Suggestion. I may use a combination of things but the water weld should get me started since it may be slightly wet even after it's been drained. I was thinking some 3000 psi marine epoxy as a final smear on product. The stuff is tough as nails but it has to be dry to apply. I'm pretty handy as far as electrical goes but without my trusty multi-meter I couldn't do much out side of clip a couple of wire, tape them off, pull the fuse that it's suppose to be tied to and hold off until I can be properly prepared. I'll know more next weekend when I get back down to the lake with some tools. FYI, the camper is set up on a season site and typically only comes home at the end of the season.
