I believe you Mattax, I apprenticed for Auto Mechanic at that time. I got an Interprovincial Red Seal on my mechanic license. I also apprenticed for Heavy Duty mechanic when it covered all areas before they split it up. Now truck and bus are separate from construction equipment. I have worked on everything from Austin Minis and MG Migets to 150 ton rock trucks, drag lines and loaders. This ticket also has an Interprovincial Red Seal. The Red Seal lets me work across Canada except Quebec. Worked on Detroit Diesels for years. Had one come in that could idle all day or bobtail without overheating. Pick up a trailer and it would overheat pretty quickly. I found a shop rag wadded on the WP impeller. Another mechanic had been working on it 200 miles away and forgot the rag in the lower hose when he put the new radiator in.
