The reality is he is not informed. Running a 12 volt coil with the 5 ohm value on the primary will let it run well, but not enhance the starting. Run a 12 volt coil for use with a external resistor. It will be equivalent to a 6 volt coil (not an issue) Use a ballast resistor out of a mid 1960s Chevrolet Belair 6 cylinder. (it just works) Connect the resistor to the coil positive side if it is negative ground, and the coil negetive side to the points. If positive ground, the resistor goes to the neg side and the points to the pos.
Next run a 12ga wire to the coil side of the ballast resistor from the area of the saddle switch or solenoid relay. Use a diode (Old diode from a scrapped out alternator is good, or one from Radio Shack (5 amp 100piv) Make sure it is polarized so it conducts toward the ballast resistor when cranking, and blocks flow when just the ignition is on. Top assure this: with the diode hooked to the 12ga wire only, use A test light from the open diode lead to the tractor frame. with the ignition on, the test light should not light up. If it does. it is wired with the wrong polarity. Reverse it. This diode will prevent the back flow into the starter which just turns the resistor into a temporary light bulb. Jim

Today's Featured Article - Trenching With a Plow - by Staff. Introduction: This interesting information came from one of the discussion forums here at YT. We thought we should place it up front so it could be read by anyone interested in putting old iron to work. [Editor] I tried something new today, and it worked so well I thought I should post it - in case it might help someone else. I'm running 100 yards of 4" drain pipe from the gutter downspouts of our house to a pond down the hill. This should hel
