Upon an fire investigation on this peterbilt the secondary power wire coming from the starter shorted out against the engine block or ground wire. As the investigation is still early I will have a better idea in a few days. I'm a heavy equipment appraiser and this is one of my fleets that I look after. *Tr

Continued to have the problem. In february we took the it in for this, and the electrical; they could found nothing. We picked it up, drove about 3 miles and the oil pressure began to fluctuate. Took it back, it was kept several days and they still found nothing. Then the fuel was not equalizing between tanks and the truck would run out of fuel. We brought it in on 4-23-08. We noted the oil pressure, the electrical and the fuel not equalizing. After 2 days, again nothing was found. Picked it up on 4-25-08, picked up a local load to deliver on the 28th. 5:30Pm the truck broke down. It was towed to the shop. The mechanic said it was an electrical issue with the oil pressure system. The next morning a mechanical gauge was put on the truck and showed no oil pressure. A gear had sheared off the oil pump. It was replaced. We pick up the truck on 5-2-08, would not start and had to be jump started. Drove approximately 30 miles the engine threw a rod through the side. It is still in the shop. Cummins opted to rebuild the engine rather than replace it. The truck is equipped with a sleeper which we are afraid to use because of the wiring. We have been told that our truck is not the only one with oil pump failures. Therefore we would like to request a full investigation into this matter. *Tr
