Got pissed off said " F-THIS!" Went and got my huge 750 cranking hours BRAND NEW Marine deep cell threw it in, hit it with 1 shot of starter fluid and she fired right up. I guess a little voice in my ear reminded me of this happening before when I bought a 95 Chevy van. Beautiful van but of course it's sitting in the yard now with no transmission. Duh.

The battery that was in my 65 was not holding charge so I would charge it then work, cranked really well for 3 minutes but I guess it never makes quite a hot enough spark if it's a shot battery!

Anyhow the whole point of this (for the short term) is just to be able to lubricate the engine for the time being. I do want her up but at least I can keep her from degrading.

I'm thinking it would prob be a good idea to put that bypass in at some point too.

And THANK YOU sooooo much Ken! Your calm reminders kept me (somewhat) sane!

A lot of work to do she gently backfires so I will try to rotate the dist as per the instructions in PErTronix kit. And the carb is pretty bad especially accelerator pump, but at least she starts right up.

Good deal. I would suggest doing what the instructions recommend. No ballast, no resistance wire. Notice that 12V goes directly to the module no matter if resistance wire is used or not. This is the BIG MISTAKE folks make about using resistance with Pertronix. They wire it up like the points were wired. I fear that is what the other guy did.
Best to eliminate resistance altogether before you slow fry the Pertronix.

Electrical is not my thing so just a thought.
The resistance wire starts at the plug in the engine compartment. Disconnect it, turn the ignition switch to the run position. And check voltage at 18-p-3 on the R.H dash bulkhead connection in the wiring diagram. It should be 12v. If so pull the resistance wire and pin out of the plug and replace it with a new 18g wire and pin (not a resistance wire) and connect it to the coil. Then connect the Pertronix to the coil. No more resistance wire and 12v at the coil.

That's a lot of work and it's 6 extra voltage drop points, 6 extra resistive terminations and 4 feet of extra wire with some resistance.
A straight wire would be best.

Sorry, yes it's in regards to your post. Your idea will send voltage to the coil. That's true. I am describing the "tortureous path" of that method. Count the terminations and the length compared to one direct wire. I've seen you're other posts and I think you are more knowledgeable than you have said. So see what you think.
