Instant O/O and Load boards

I was driving a Western Star out west and the truck shut down on me one day. It did it just that once. Cjecked the truck over and found nothing. The next day 3 hours into it and the truck shuts down. I find a lose 12 volt power supply to the outlet by the key switch. We could start the truck with that outlet. But that wasn't the problem. The ignition circuit was overloading causing the truck to shut down. When the breaker cooled the truck would run again. So we hot wired the ignition circuit and I went where I had to and then took the vavle cover off to inspect the wires. The ingnition circiut was also tied into the engine brakes. I did not find anything. But the truck never shut down again. To me it does sound like you have a short that is slowly drawing power through a breaker when you turn the a/c on. This is overloading it and it seems like it is somehow connected to the ecm/ignition circuit possibly at the fuse box. Without being at the truck and looking at it this is the best that I can do for you.

 

PHARM WAKE-UP I JUST THOUGHT OF SOMETHING. Does the guy that wants to use you authority have a hopper-bottom trailer? If he does you could pull it an work out a deal with him.

 

You need to find one closer to home.

 

Truckpaper shows several and you might try Wilson Trailer

 

Pharm on the mechanical side as mentioned before I would look into the starter cables, the main ground strap which might be braided steel looking as well, the relay and all of the battery connections. Also it would be worth checking the specific gravity if your batteries allow access to the cells. To me it sounds like the culprit could very well be the alternator or the voltage regulator which often is built into the alternator. The click click sounds are normal, it's all of the solenoids and relays being powered up and closing the circuits. Another real possibility is the fuel solenoid, if it's starting to crap out it WILL shut your engine down without warning and if the circuit is crapping out small voltage drains like the blower motor or headlights could push the voltage below what the improperly functioning fuel solenoid now requires to close the circuit. The good news is all of these are easy fixes under the shadetree, with basic tools. If you can narrow it down to what is specifically the problem none of these are very expensive fixes as truck repairs go. Best of luck and keep us posted.

 

well pharm u never know with them starters all it takes is one loose nut and it would cause it to ark i had a truck that would do the same thing put a new starter worked fine for about a month and it started shutting off and wouldent start i crawled under and what do u know the ground cable off the starters vibrated loose enough to ark causing it to shut off and not turn over for a lil bit

 

i've said it before and i'l say it again. if you have a problem that could be something that was just replaced, then that's probably it. the failure rate on new parts is very bad
