I replaced the coil after reading a post about a bad one that sounded strangely familiar, but the wiring was so bad and the resistor needed to be bypassed so I decided to rewire the ignition system. Ran all new 1 ga grounds with soldered connections and dielectric... used 10 ga wire throughout, also soldered and dielectric... finally, last night I hooked up the battery to just bump the engine without the distributor... turned key, no bump... turned off... pulled battery cable... whiff of smoke coming from generator... at that point I wanted to release the parking brake and lay down in front of the wheels.
Obviously with all the changes the PO made, the wiring diagram is not accuate. I removed all the wiring under the hood and dash... and managed to screw up the temp gauge tube getting the gauge cluster out. Since I now cannot seem to find a simple igition diagram that covers my setup to study- 12v, generator, regulator, internal resistor coil, key start- I will list what I know, and would appreciate any help.
Ground from Neg Bat terminal to engine block
Ground from engine block to frame
1 ga from Pos Bat terminal to middle post on starter
10 ga from F on generator to Fld on regulator
10 ga from A on generator to Arm on regulator
10 ga from Bat on regulator to Amp meter
10 ga from Amp meter to Bat on ignition switch
10 ga from Bat on ignition switch to middle post on Starter
10 ga from Ign on ignition switch to S on starter
10 ga from Sol on ignition switch to + on coil
10 ga from - on coil to stud on distributor
I know I've screwed this up big time. It ran beautifully for a week... then I started to "fix" it and now it won't even turn on. Knowing my luck it probably was just out of gas to begin with. I'm about to part this out, which will be a great deal figuring just about everything is new now. Lost interest... no. Lost my mind... definitely.

I think I might have a couple of ideas after reading your list. -shouldn't the 10 ga from the IGN terminal on the switch go to the coil to provide constant voltage for ignition? -shouldn't the 10ga from the SOL terminal on the switch go to the S terminal on the starter? I'm not totally sure these ideas would work. As a newly licenced wet behind the ears technician, automotive electrical is one mystery I'm still learning to deal with. I hope this might help you out. Don't give up-when you finally figure it out, you will feel SO pleased...trust me on that one. Regards, Wannabe

We're all here to help or get help or get lost from less interesting jobs. Good luck and there are many here who can help. Do you have a good shop manual? There are some other sources of info on rewire. Just let us know what you need. | | |

I've got to be gone about a week on business... I'll let you know how things are going when I get back... and no, I won't tell you where the truck is while I'm gone... :p
