So the new resistor connections have to be sealed up, not just the lid of the IDM? Will a dot of hot glue work to help hold the new resistor and seal up them connections??

Splatts, if you haven't seen the above link you should review it.
If you are using the small resistor I think hot glue would be fine to secure it. Because you have used a hot gun to remove the cover I think you may have already seen the link. If you have any questions just ask, and good luck.

I got some dielectric silicone we use at work to help with waterproofing high voltage underground cable. Just a dab on a q-tip should seal it up. I have been reading a lot on this. It's all or nothing from here. Ha ha

I used some cheap RTV sealant that was black and I bought it at harbor freight. Its important that you apply an even bead of sealant around the base then carefully place the cover and clamp it in place or put some weight on it. I let mine set overnight and It was fine.

I got grey rtv to seal the lid, but I kept reading about sealing the sodder on the new resistor. I figures the dielectric silicone would do fine for that, and a dab of hot glue to hold the new resistor in place while I heat up the sodder a bit for the connection. I read of a few guys that just heated up the old sodder and didn't add any, cause too much is bad I guess.

You should really try to remove the old solder, they make some stuff that's called solder wick to clean the old solder off the pads, Radio Shack would have it I think. It is necessary to add a little solder if you don't get the old off for a good solder joint, and its not necessary to use a lot of solder, its preferable to be able to see a little lead definition . You don't need to cover the solder with sealant.

My dually is feeling gutless. Can't pull hills for crap with 1500lbs on the back plus the weight of the steel flatbed. I have searched for leaking up pipes but havent found any signs of leakage. I will definately have to wait until tomorrow night so I can swing by RadioShack and pick up a few things it sounds like I need.
