Your son (or you) also fried the alternator. If there is one thing an alternator cannot stand it is reverse battery connections. Diodes in the inside (big ones) convert AC to charging DC. This setup allows current to flow in the direction of charging only. A battery hooked up backwards causes the diodes to appear as short circuits to ground. This pops the internal silicon parts of the diode. Rebuilding the Alternator (probably a diode pack, and new regulator is needed) You state that it is positive ground!! Almost al alternators are negative ground. Farmalls were positive ground from the factory with a 6 volt generator, but when it was converted to an alternator it was probably Negative ground. If there was confusion in this regard, bad things do happen. There are positive ground alternators, but special ordered, or for particular vehicles. Not common. The Delco 10SI alternator has a external diode (probably OK) that allows ignition voltage to excite the alternator starting the charging process. The diode prevents electricity from reversing in that circuit keeping the engine running when the key is off. The third wire should go from Terminal #2 on the alt to the big post, (short wire). If the diode in the ignition wire mentioned has its index white band toward the alternator, it was a Negative ground battery/charging system. Jim Best of luck, and always go from pos to pos and neg to neg no matter what the ground is when jumping.

Today's Featured Article - Harvestin Corn in Southern Wisconsin: The Early Years - by Pat Browning. In this area of Wisconsin, most crops are raised to support livestock production or dairy herds in various forms. Corn products were harvested for grain, and for ensilage (we always just called it 'silage'). Silo Filling Time On dairy farms back in the 30's and into the first half of the 40's, making of corn silage was done with horses pulling a corn binder producing tied bundles of fresh, sweet-smelling corn plants, nice green leaves with ear; the
