I'll check all the wires, but the tower to coil one seems important to check first. Quote Link to comment Share on other sites More sharing options...
Tracksbeatwheels Posted April 15, 2022 Author Share Posted April 15, 2022 Hi again Reg, I used my ohmmeter and the wire to the tower is good and the carbon rubbing area to teh tower reads good, the wires are all good so I am going back to the timing. it must be that the impulse drive is tripping before the rotor lines up with the #1 spot in the distributor, it looks right, but I can{t tell precisely so, I{ll start at the points making sure they are open on the high lobe, then put the engine at tdc plus the 10 to 15 mm, go back and push the mag away from me slowly until the impulse drive trips. and check for spark. Everything was working fine, like I said when I shut it down a few months back. I{ll post how this turns out. I{m sure its something simple I an doing wrong or not doing.

In your first post you said the wires were wrong, and very possibly so. I am looking through and old manual, and it is saying there is right hand rotation mags, and left hand rotation. When you routed the wires, you are sure which direction yours is turning? I went by the manuals and what I understood, but untill I pulled the cap and watched while cranking, I was backwards. I had no fire at all on a new motor, untill I got that straightened out. You might be right, I'm just throwing out there what happened to me. Mark counter Clock wise for TD's Serial number with a 'D' See chart below. This is because if you look at the chain of timing gears, the TD's have an extra timing gear, giving a 'swap' in rotation compared to gasoline engines Quote Link to comment Share on other sites More sharing options...
reggievonruffnut Posted April 15, 2022 Share Posted April 15, 2022 My dozer stopped starting again, I diagnosed with a timing light that the spark was inconsistent, if the plug grounds out you don’t get a light flash from the timing light , this was being caused by the plugs breaking down and grounding under compression, they all tested ok out of the engine giving good spark and the timing light giving a good flash. reg Quote Link to comment Share on other sites More sharing options...

Tracksbeatwheels Posted April 28, 2022 Author Share Posted April 28, 2022 Hi Everyone, IT RUNS!!!! Like so many car problems, I did so many things that I'm not sure what the problem was. I reset the points, set the timing so the impulse drive just tripped, and cranked away. It backfired, so I checked the firing order and swapped two wires, cranked again and she fired up! Runs well. Thank you Reg and everyone else who responded to my cries for help. Without this Forum, I don't think I could have ever solved the problem. Now, I can get down to changing the hydraulic fluid for the blade and welding some cracks in the blade. Hard to do when I couldn't drive it over to the shop. SO HAPPY!!!!, THANK YOU, THANK YOU, THANK YOU ALL! TRACKSBEATWHEELS 2 Quote Link to comment Share on other sites More sharing options...
