Ive got a super 88 that i bought that sat under a tree since 1997, after going through the engine, a new distributer, coil and starter, i had it running great, ran nice and strong. now i brought it out yesterday and hooked up to the bale rack to pull it up the hill, and as i jumped off and hooked up it died, i hooked up jumped back on and hit the starter button and nothing, pull started it and brough it back to the shed, replaced the starter button, no voltage going through it, and now nothing, even with 12 volts at the battery, i get it all teh way to the starter, but wont spin over, took the starter off and bench tested, it worked great, in confused, and everytime i hook up the neg cable i get sparks, and i know i have a draw, but the it has just thw wires needed to run till i had more time, so it has just a flip switch to power the coil. im confused as to why it isnt spinning over and draining a battery in 15 minutes
 
You may have two separate problems in terms of starter and die down. I'm thinking that the battery grounds to the fuel tank/ console support metal work like an 88. As others have suggested here run your ground directly via a new cable from battery to one of the bolts that mounts the starter. You may have a problem with the ignition switch or an area where a live wire or cable is shorting to the chassis. For the short term disconnect the battery when not in use and inspect all wires and cables for bare spots and rubbing. Such shorts can be a fire hazard. With the tractor sitting as long as you have stated that it has deterioration has no doubt settled in on the electrical system with perhaps rodents making the problem worse. The ignition switch could be ladened with moisture causing internal current movement.

Exactly. The original ground from the factory was good on those for about two years. After that,they started to rust between the cowl and frame and the ground was gone.
 
i got it to start, i had a very bad battery draw, it was the none functioning generator, and the ground is the first thing i changed, it does go directly to a bolt on the starter, and i did get it running but it runs very rough, i played with the timing and it only got worse, so i set the distibuter back to where i marked it, and went thorugh the carb cause it was leaking gas, got that fixed and it still runs like hell, it was running great. im putting in another new set of plugs, and going to do a compression check cause im getting blow by
 
I'd look at the seat and anywhere you stepped or anything you moved. Sounds like a
hot wire lost some insulation and you made it contact with the frame.

I also had a problem that took something odd to catch my eye (can't remember). Did
the same as you, a tune up...thing would run then all of sudden run rough or just
die...the new coil wire was popping off the new cap but not all the way. Never saw that one
before.
 
everything is brand new, its loving points so far, so i checked my coil and it says internally resisted but its sending 12 volts out, and im going to put in a resister and see if that helps, i reset the valve and then stopped working on it to drive semi for corn silage, so itll be a few days before i can look into it again, it was running beautiful but its been a fight to keep it going, it seems to burn out a point in a week, even playing with the timing makes it worse, i have completly rewired it to just the bare minimum till funds are better to do it right, no guages are hooked up, i have a manual o.p guage on the block but thats it, no annemeter and coolant temp isnt hooked up.
