If you want to go to a Generator system (to retain the stock look) this stuff is required: Also assumes a coil ignition. If Mag the coil is not needed, but a oil pressure normally open switch is needed to start the alternator. 1} A 12v battery as big as will physically fit in the box, of good quality/warranty
2) A voltage regulator for 12V positive ground Three terminal is good if you have a three terminal 6v now.
3} a 12 volt generator from a 12V IH tractor (this includes "SOME" MDs SMDs SMTADs, 400D 450D and later tractors with Stock 12V systems.
4} a 12 volt coil with "no external resistor needed" written on it.
5} 12V headlight bulbs that have the same wattage as the old 6V bulbs (do not go bigger hear, they burn out the dimming resistor)and a tail light bulb.After polarizing the gen (brief connection between bat terminal on the reg to the Arm/Gen terminal on the reg with engine off before starting) the system should be good to go. If an alternator is used, the battery, bulbs, and coil from the above list are still needed. The battery is hooked up negative ground. The coil is also hooked up differently (negative terminal to the distributor with Neg ground)
1} an alternator Delco two wire, or Hitachi are fine (the Hitachi fits under the hood with more clearance, and has more adjustment for the belt)
2) a 3 amp diode with 400PIV rating (actually an old good diode from an alternator output pack will work, but a two lead diode is easy. Hook up the alt so the belt runs true.
Attach the Big terminal to the Load side of the Amp gauge (I like to replace the amp gauge with a gauge that reads to about 10% more than the output of the alternator). Some Delcos can put out 100 amps. I also like to put a fusable link (special wire that melts at a certain amp rating, available at NAPA etc.) in the wire going to the starter's terminal from the battery side of the amp meter. This keeps the smoke from coming out of components, and is often not done. Auto makers never build cars without fuse links in the system. It should also be fused to 10% over the alternator output.
Assuming a Delco, (hitachi are similar and described in the archives) The diode goes between the number 1 spade terminal on the alternator and the coil side of the ignition switch it is set with its triangle pointing to the alternator, and the line at the alternator end . If Mag equipped, The oil pressure normally open switch is placed between the #1 terminal on a delco, and the Battery positive post (at the starter switch), no diode is needed.
Hook up the #2 spade terminal on the alternator to the big terminal of the alternator. It supplies the sensing voltage to the regulator. Change the bulbs, and it should be good to go. Good luck, keep us informed. JimN
