School Bus Body Wiring Modules

The video shows you where to find the wiring control modules for this bus model. The modules are a printed circuit and can’t be accessed but through the years we have replaced very few of them.

The Cummins ISB 6.7 Diesel

I have to admit that the Cummins ISB 6.7 Liter diesel engine is the superior model for medium duty power in our school buses. The fit and finish we found with the new international buses we received this year is second to none. The IC people are listening to their customers with new changes made… Continue reading The Cummins ISB 6.7 Diesel

The Basics and Keeping Up With Technology

Staying On Top of Your Field Finding ways to analyze problems more efficiently that don’t take up a lot of time is like gold to me. The one thing that always wins over mechanical and electrical problems is experience. Once you’ve been through the “stumbling around” phase the second time around is always easier. Going… Continue reading The Basics and Keeping Up With Technology

4L80E GM Transmission TCC Failure

We recently had a 2006 one ton cube van with a slipping/shuddering transmission (4L80E). The transmission code indicated a torque convertor problem. The first step was to remove the transmission oil pan and check the filter. It was advised by one of the transmission shops to tear open the filter and see what’s inside. We… Continue reading 4L80E GM Transmission TCC Failure

It just happened out of the blue as with all electrical faults so we needed to find out where the wiring originated and see if there was any output from the source. I… Continue reading School Bus Wiring Problem – RH Signal/Marker Lights

We were working on a Thomas C2 conventional school bus at the time and what… Continue reading Multiplex Wiring Troubleshooting on a School Bus

School Bus Vandalock No Start Possibility

I can talk from experience that I had a few service calls that involved the vandalock system. When engaged the bus will not start which is the main reason they were installed. They interrupt the starting circuit until they are unlatched at either the side door or rear emergency window. This pertains to the pusher… Continue reading School Bus Vandalock No Start Possibility

The DT466 Electronic Diesel Engine

The DT466E Diesel Engine Memories The DT466E International diesel is no more mainly because it could not meet emission standards. It’s one engine that performed only as good as the oil pressure that supplied the HEUI (hydraulic electronic unit injectors). They had a tendency to run rough when cold because of the lack of supply… Continue reading The DT466 Electronic Diesel Engine

School Bus Mechanic – Kayaking and Upcoming Summer Schedule

The video below is my kayaking adventure on Canada Day. I’m pretty sure one of the bird chirps you hear is a bald eagle. I saw him roaming the skies later on that morning and the wing span must have been 5 or 6 feet. So I’m not doing too much talking during the shoot… Continue reading School Bus Mechanic – Kayaking and Upcoming Summer Schedule
