These operators just love to pull and cut wires when there is any problems, ha ha. Yea your harness is gonna be a pretty penny and thats just the start of it. Im having trouble finding parts for the front axle, both four wheel drive units had to be overhauled, parts alone were around $6000.00! and im not even done yet. Anyways to give you some advise on your electrical problems, if you have a voltage tester that can test for 12 volts then first test the battery when the engine is off, if you have more then 12 volts (usually around 12.50/12.70 somewhere around there is good)it should start no problem, if so then run your engine and test it again. The alternator should be putting out anywhere from 12.50 to 14.00 volts. If the battery is not getting that many volts then you might have a bad alternator but you then should test the wires coming out of the back of the alternator, if you get the same reading there as the battery then you have a bad alternator. Now if you get a different reading there then the battery, like more then 12 volts, your alternator is ok but this means you have a break in the wiring harness somewhere. This is a big process to trace wires and try to find a break. The easiest thing to do in this situation is go down to your auto parts store and ask for a GM internally reagulated one wire alternator, commonly found on mid to late 80s' chevys, also hotrodders love to use them on their cars because they make wiring easier. When you find this alternator, put it in place of the alternator on the tractor now, you might have to make or find a new upper bracket to hold it,and maybe a longer belt. Then just run a 10 ga wire from the alternator straight to the battery, this will give your battery the constant 12-14 volts it needs to remain charged. Another thing to is always make sure you have good grounds, any corrosion will not make a good contact and it will seem like your battery is dead, remove and seal any rust, oxidization, and paint. Whoa look at the time, gotta go, good luck, let me know how it works out.
