Conversion with 12V generator - by Patrick H. DykesThis is an easy way that retains the originality you may be concerned with. Simply obtain a corresponding 12V generator (making minor bracket or mount change), or have the existing 6V generator converted by installing 12V field coils into the existing generator case. How could it be easier? (Along with original appearance, there is another distinct benefit to this approach, and that is, that a generator will charge a dead battery; an alternator will not! In fact, operating an alternator in a completely discharged system can damage the alternator, since it requires an electrical source to energize. It is true, of course, that any generator system will show "discharge" at idle, while an alternator does not. With the quick recovery of the generator system at "r's", however, only the most severe loads would overtax it. But, it's your decision!) Conversion with an alternator - by Patrick H. DykesThis is probably the more widely used approach but some originality in appearance must be sacrificed. The minimal wiring changes are no big deal. Use a DA plug (Patrick's has 'em: $19.95) which allows discarding the old voltage regulator. Here, the "Batt" wire that went to the regulator is extended to the post of the alternator where it meets the red wire of the DA plug. Then, "heat" is picked up at some convenient "ignit" spot (the switch or the coil wire) and a wire run to the white DA wire. Presto! The old regulator and the "field" and "arm" wire of the harness are also eliminated. Very tidy. Here are the items and changes that will be needed, according to which procedure is adopted: 1. A 12-Volt battery. (Pick a size that fits the carrier.) 2. A 12-Volt regulator. (If using a generator.) 3. A 12-Volt coil 4. A fistful of corresponding 12V bulbs (dash, stop/tail, etc.), including headlights. 5. An ignition ballast resistor (NAPA p/n ICR-13), which will be installed in the wire from the ignition switch to the coil. (You've seen 'em on the firewall, like a '55 Chevy.) 6. A voltage reducer for each accessory, such as radio, and/or heater (install it before the switch!). (NAPA/Echlin: VT 6187) it's expensive. 7. Use Runtz gauge resistor (see page 18) |
