That’s what gave me the idea for a theft prevention device (hidden switch). If a thief can’t start the car with a master key, or even hot-wire it, he can’t drive it away (unless he notices that extra wire spliced into the OD harness 😁).

Well, I got to ciphering and finally realized it would not matter whether powered off the IGN SW or RELAY, as the OD momentarily cuts the IGN regardless.

Sorry to bother you.

I was just answering your query re: the Pertronix install (no relay). Don't know why the stupid ‘quote’ feature won’t work for me. Everybody seems to get different results with it.

KULTULZ (10/23/2026)

Was the IGNITOR wired thru the IGN SW or a free-standing relay circuit?

Merely exchanged for the points, per Pertronix instructions. Might have performed well in a car without electrical issues. But, I think that while 6V is adequate, just not enough juice left over to cover problems (likely the impetus for 12V).

"I once installed the Pertronix for 6V +grd in my OEM LOM dist.   Combination of worn gen., corroded relay assembly contacts, etc., made the idiot light glow when the solenoid hold-in coil activated with headlight on, and the motor would thus start missing at high RPMs. Reinstalling the points cured the issue."

... hmmpf  ...

Think I will contact their TECH and see if they have a go-around.

DANIEL TENDER WROTE -

Just that it is possible to improve performance while retaining the 6SEMV system. He’s not doing a concours restoration.BTW:

His problem with a 6V Pertronics is common (overdrive draws too much juice).


#1 -
I owe you an apology. Ted and others later corrected me as to being able to use a 12V DIST on a 6V system in another thread.

 #2
While PERTRONIX does offer an IGNITOR for the 6V NEG GRD LOM DIST, I have read casual references to the OD electric control interfering with it's operation (I believe the momentary electric supply cut-out) confusing the IGN MODULE?

Do you have any other info/experience?

BTW - The FDT-12127-B1 DIST ASSY the OP showed earlier was a 1956 FORD 292-312. I would think that one would have better advance curves if he kept LOM..

Ted yes, for timing I use a timing light and yes the mark moves when I rev it


If you see the timing mark advance with the timing light, the advance should be good.

If you put a vacuum signal on the vacuum advance canister (with a hand held vacuum pump or mouth suction), does the breaker plate advance and return (after releasing vacuum) easily and does the vacuum canister hold vacuum?

If that low of mileage, the DIST advance may be hanging but not totally dysfunctional.

Exactly what is (are) the drive-ability concern(s)?




Hey KULTULZ your reply came to Greece! I wish I'll get it working with such smaller problems 😅
