OK, confirmed you have the front mount distributor and a 12V battery but is the wiring correct for a 12V conversion? Is the original 6V generator and voltage regulator removed and an alternator replaced, either a 1-wire or 3-wire? The front mount also needs the original Ballast Resistor in the coil circuit regardless if 6V or 12V is used. You also will need an external in-line 1-OHM resistor in the coil circuit if using the original 6V Coil. Eliminate the extra ceramic 1-OHM resistor by switching the coil to a verified 12V coil. The other wiring needs to remain the same as the 6V; the 3-Wire Starter Motor with the RELAY (Solenoid); AMMETER; NEUTRAL SAFETY START PUSHBUTTON, IGNITION KEY SWITCH; and all wired correctly. Lighting kits were optional accessories. Regardless whether you use a Generator or an Alternator, you must have a fan belt tensioner device attached otherwise you will never charge the battery. The original 8N and up generators all had a belt tensioner but 12V conversion kits are not all the same. Some have a tensioner and some don't. 12V conversions can use the original AMMETER (preferred) or switch out to a VOLTMETER. It is also important to have the original manuals too so you know not only the 6V wiring setup but all the other major systems as well.
