If the alternator is a one wire and working, you can and should carefully remove all the wires from the regulator that are still connected. cut them pretty short, and put shrink caps on them Or shrink tube and a touch of liquid tape to close the end. Some one wire alternators have access to the #1 terminal in the edge connector if it does and you test it with the engine off and ignition off, it should be a ground. Test by hooking the test light alligator clip to the big output stud on the alternator, and touching that spade terminal. If it lights the light, good so far. Start the tractor and run it up to 1/2 throttle. Then touch that same terminal#1 with the alligator attached as before. there should be no light (be careful to not touch anything but the terminal with the test light. (one way to make it easier is to attach a 1/4 spade terminal to a 2 piece of #12 wire, then strip the wire for 1/2 inch so you can touch it easily. Put that on the #1 terminal and test at the stripped end). The #1 terminal becomes a electrically hot terminal when charging. Because the terminal is hot, and the test light is connected to hot, the test light will have 12v on both leads and not light!. The test light is acting like a charge light on the dash. If you shut off the tractor, the light will light again. If this works, use the information below to attach a indicator light. If none of this works, there may be no way to attach a dash warning light to that alternator. If it is a 3 wire alternator setup correctly the issue is more easily dealt with. The light in the dash needs to be an indicator light for 12v operation and have 2 leads (not a lead and a ground (which the original light might be.) The new light will be placed in series with the #1 terminal and the ignition key I terminal. So one of the dash indicator light terminals attaches to the #1 spade in the alternator, and the other gets 12v from the Key. (not the ignition coil because the ignition coil is fed electricity through a resistor wire from the key to the coil. Jim

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
