I just bought a nortrac 204c. nice tractor but some problems from the start. rear lights did not work due to connectors not connected, hour meter did not work northern sent new one and ended up wires not connected behind fuel tank. Now the problem I can't seem to find. The glow plug fuse keeps blowing (10A)needed for cold weather starts. If I jump both sides of fuse box it works fine. The only wire I can see is the green wire that goes to top of glown plug. northern seems to think it may be relay but not sure. ANY HELP WILL BE APPRECIATED> Nice tractor just make sure you have some mechanical ability. This tractor less than week old.
