I am working on my old snowcat with Ford 300 cu inch engine. I am not sure what the issue is but it seems battery cable related.
If I turn the key to omON a fan comes on. Turn to START and I hear a little spark and then things go dead. Turn key from START to ON and no fan. Wiggle things and I can get the fan to work. Turn to START and same thing as before. (Have yet to see the spark.
Each cable is all one piece from the lug end to the battery clamp. The wire goes into the clamp with the insulation right up to the battery clamp. Cannot see any bare wire or corrosion. The battery clamp and battery post look clean. The lug end looks good.
I am thinking there is an issue under the insulation or within the battery clamp that I cannot see.
I am think I will just get some 2 gauge new battery cables.
I have wire brushed the ares where the ground wire connects to the engine.
While not 100% conclusive, it seem when I wiggle the red cable the fan comes back on.
