Tractor running fine. After approx 2 hours i shut off and got no crank on restart. No lights either . .just a weak whine behind the instrument panel. Thought maybe alternator died and somehow battery drained (but how with no lights running??). Tried boosting from truck . . got lights but weak crank. Two hours later tried again with jump . .still weak crank but started. Once running, glow plug light stays on at high rpm and all three dash lights flicker at low rpm. I hear the glow plug click on and then off after 3 seconds when i turn ignition on so seeems to be a mysteery light only. Also get no headlights or flashers. Without boost i get absolutely nothing.
So . . thought perhaps bad ground . .or loose battery terminals. However with truck clipped to the battery cables issue still present.
Grond wire from batt looks and feels solid. How do I check that? Or . . is it possibly a relay that can be partially overcome when I attach the second battery? Or is it a myterious computer controller that I can't trace?
I should mention that I don't know how to actually test a relay!
Thanks in advance. Dealer can only suggest weak battery connection . . and would prefer I trailer it an hour into their shop.
