What are "both those things" that you're talking about? You only have to unplug the fan solenoid to make the fan run, you don't need to touch the...
If all you want to do is make your engine fan run all the time until you can get it fixed, just unplug the electrical connector on the fan solenoid.
I just looked at the schematic and yes, the marker lights are tied together somewhere in that chassis harness, but I do not know where. Be fore...
If you show power with an open circuit and it goes to ground when hooked up, it's a sure sign of high resistance. 99% chance that you are going...
Oh, my bad, 389's have a different set up, I was thinking of 379's. All the powers left/right are totally separate. Here's a schematic for your...
Follow the harness down, there's plugs right behind the bumper by the hood hinge. You'll find two 3-wire plugs, one is for the headlights and the...
I would agree. I just checked a 39 MT starter (that does require a 2nd switch) and the solenoid coil has 0.7 ohms, so almost 20 amps on that one....
I posted the flywheel specs here a while back. I have yet to see a flywheel that was cut too much. Just take a measurement before you take it...
Either way, it won't hurt to keep it. Unless you can find out for sure that you don't need it (which isn't going to be easy), I'd play it safe....
There shouldn't be any confusion. Pete started reusing old VIN's, so sometimes you get an option of 2 trucks, but they are decades apart. The...
I'm not sure if this is a question or not, but it would be no different than other relays. Most relays have the schematic on them, follow that....
The most useful thing to me about an amp gauge is knowing the battery state of charge, the volt meter doesn't tell you that. If your batteries...
Versajust LS are the ones we used on the garbage trucks.
Do these trucks do a lot of stop/go and/or run a lot of hills? Back when I worked on garbage trucks in the mountains, we could not use Meritor...
You must really hate your grandma. I know we're joking here, but this is actually on point. There are people out there that use these "back...
I'm not a gynecologist, but I'll take a look. :D
There's no such thing as a good EGR on a diesel. Why don't you tell use a little about your truck and the problems that you're having?
No relation to AdeptApe, but I've watched some of his video's, they're pretty helpful. Be careful with the "diagnostic laptops" that you find on...
Are you a owner/op, do you have a small fleet, or something else? To get ESA legally, you'll need an Eportal account, which we pay $300/year for....
The software is Paccar ESA. The programmable options will all be in the "Program" tab.
