Last night I finished the resistor bypass, replaced the glow plug relay with a NAPA ST85, installed new AC 60G glow plugs and spade connectors, on one truck that was having starting problems. This morning with it cold, it started right up, yea! I learned all of these things from this site, and I'll be doing the same for the other truck in a few days. I also installed two new EXIDE 31XHE batteries ($95 each at Tractor Supply with 10% off coupon) in one truck.
I've also had various other electrical problems with both trucks, namely failed lights and turn signals due to broken wires, along with multiple breaks in my windshield washer tubing. I had my suspicions but the gnaw marks, turds, and rocks and pieces of my truck on top of the air filter cover were the obvious signs. I caught the little bugger this morning with a $5 Tomcat trap from Walmart. It's the same one my wife almost got a few months ago with a hoe, but only skinned its tail.
