Bob M is very correct. To change to a volt meter (that fits in the same dash hole) do this: First see if one terminal of the meter is grounded to the case of the meter. If it is, and the meter has only one wire connection to it, it will not work well with a positive ground tractor. Volt meters are often one wire devices with the case grounded. A positive ground tractor would take a meter that was for positive ground. Make this determination first before hooking or loosing a receipt. With the right polarity meter: Disconnect the battery at the non-ground post. Remove the existing amp meter and remove the wires from both terminals. Use a piece of rubber hose that the terminals will fit into, and slide it onto one of the bundle of wires taken from one post. Use a small (preferably brass) bolt and nut to fasten both sets of terminal rings together, eliminating the Amp meter. Tape up the connection well with black tape. Slide the rubber tube down over the connection to assure it is insulated from the metal in the dash, and other wires. Fill it with silicon RTV sealer (blue goo) to assure it is moisture proof. Connect the ground of the new gauge to a bright metal ground and put blue goo on that to keep it from rusting. Attach the other wire/terminal to the ignition switch so that it is on when the tractor is on. This is not to say it would discharge the battery, if wired to the bundle just described, but it is the way it cannot. Install the gauge in the dash and go. I hope this works out for you. Keep us informed with a followup when done. JimN

Today's Featured Article - Tuning Up Your Tractor: Cooling and Fuel Systems, Hoses and Belts - by Curtis Von Fange. Our tractor is coming right along. The old oil and filter has been taken to the recycler and the air filter replacement has breathed new life into our motor. Let's take a closer look, now, at the cooling system since it has to work so hard in the summer heat. Cooling systems can be real cantankerous in their old age. Radiator cores clog up with rust, lime or other mineral deposits and the fins clog up with weed seeds and debris. The metal headers slowly corrode away from years of use and
