If you do, you need to take the alternator output wire to one terminal of the ammeter and the other ammeter terminal should connect to the battery. Actually one of the ammeter terminals is where most of the electrical loads should be connected, that way the ammeter reading will reflect whether or not the battery is being charged, hope that hopes. | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | also if you're using a ballast resistor I assume you have a 12V system, in which case you need to bypass the resistor when the starter is in action - normally with the 12V starter, if you've swapped to that, a wire from the side terminal of the 'box' atop the starter to the output side of the resistor would do that ... that wire needs to go thru the ignition switch as well, so the engine can't start without the key on .... if you're still using the 6V starter you'll have to rig another setup to accomplish the bypassing so the coil gets full voltage when cranking
Bill | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | my system is going to be 12 volts, the only thing that is 6volt is my starter, which they say i can use as long as i don't crank it over for a long time...so how would i wire it using my 6volt starter, i don't know if it makes a difference, but i have the foot button to start the starter, any diagram to go by... | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy 696969, if you replace the contact switch assembly on the top of your starter with one from a twelve volt starter, it will have a ten gauge terminal sticking out of the side of it. That terminal is where you attach the resistor bypass wire that red58 mentioned, just run a wire from that terminal up to the resistor output terminal as red58 said, hope that helps. | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | where would i get this contact switch, i look in the catalogs and can't find one... | | | | | Joined: Feb 2002 Posts: 12,029 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Feb 2002 Posts: 12,029 | used is your only choice unless you happen to have an old time auto electric shop nearby that might have one laying around

Wire 10ga. from large connection on starter mechanical switch to battery connection on ignition switch. Run wire from ignition terminal on ignition switch to one side of ballast resistor, run two wires from other terminal on ballast resistor, one wire to the distributor, the other wire down to the small terminal on the starter mechanical switch, you have to purchase a new mechanical switch with the small terminal, tclederman posted a link above to the switch available at Napa, hope that helps. | | | | | Joined: Oct 2011 Posts: 118 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2011 Posts: 118 | thanks 3b for info., slowly learning the electrial, thanks to you guys...
