Hot lug
I was replacing the drain control on the water seperator because it had started leaking. After I finished to started the truck to check the leak. When I reached down to feel underneath the drain switch my arm laid on a part with I think 4 wires on it. This part is just to the left of the drain switch. The lug that the largest wire is connected to was hot enough that I couldn't touch it for more than 1 second or so. Anyone know what that part is and why it might be hot on the lug so quick?

It will get hot if the the contact isn't good inside, you may have a GPR about to go bad. It generates heat when there is high resistance connection on the inside, or like rbaker stated from a loose connection at the terminal. HTH's Lee

Just before mine went for a crap.... it used to get smokin hot !!! Like it would melt the rubber cover on the terminal !!!! If the GPR is what's getting hot I wouldn't wait to long to replace it because its almost gone !!!
