Re: Smokin
I'm trying to sort it with y'alls help. So far I have removed the resistor & wire and a another wire from the ammeter to the ign sw. I have a new ammeter not installed, old one had terminal insulators melted so posts touched the case.
Does anyone have elec diagram for a 12v conversion.? if I had that I would change out that rats nest of red wires on the firewall, one wire at a time.

As previously stated, the normal 'A' wiring diagram is all thats needed. No difference in 6v vs 12v except polarity, coil[maybe] and bulbs. Points are grounded the same as the battery whether + or - . Bob posted a diagram in #17 Last edited by Patrick L.; 10-04-2021 at 11:30 AM. |

Re: Smokin
Before I start ripping out wire here's my plan, if you see something wrong or missing pls let me know.
I have an alt not gen so delete the wire to cut out. Attach wire to disconnected distrib steel cable then to one side of ign sw. Run wire from ammeter to + coil, other side (-) ammeter goes to ign sw. Run wire from starter, to left side j box term, then other term of ammeter to right side j box. Run wire from starter to left side (+) j box Run a wire from alt output to jbox (-) I will tape the ammeter leads together to omit the gauge until I do a smoke check on my new rats nest

Re: Smokin
So I need a wire from alt output to the j box (-) right?

Re: Smokin
Your car has been changed to negative ground, which means the polarity must be swapped at the ammeter and coil, opposite of what standard drawings show. The ignition switch originally was wired between the points and coil; for some reason the PO rewired the switch to go between the battery and coil, as you found it, but I see no reason to do so. I would go back to original switch wiring - connect the armored wire to one side of the switch, the other to the red wire in the loom, and connect the other end of the red wire to the (-) post of the coil. The (+) post then connects with a short black wire to the (vehicle) right side j-box post with the yellow-black wire from the alternator.
I would also replace the cutout to firewall loom - https://www.mikes-afordable.com/product/A14406.html to replace that burned wire between starter and junction box. |

Re: Smokin
Don't worry about the connections to the ammeter, If you connect them backwards the meter will just read backwards. Easy to fix.

Re: Smokin
Thanks to all who take the time to help someone out. I re-writing my notes to make the changes, I hope we're at the bottom so I can get on with the effort, but I have ordered the harness from Mikes because of damage from the fire to adjacent wire..
