Going to install the Pertronix Electronic Ignition in my 1966 2000. Does or is my coil equipped with the Ballast Resistor? The coil is one of those smaller style, approx 4 inches tall. I have seen coils before that have it in writing printed on the outside of the coil, but mine is all rubbed off. Thanks
 
use the coil that the supplier of your e-ignition specifies.

the basic oe ignition coil on a 3 cyl gasser is a 6v coil, on a 12v system, and uses a resistor WIRE to feed the coil.

can't tell you what coil you have in your hand.. etc.

ech help at Pertronix will steer you right (toll free number). They will tell you that 4 amperes steady state coil current is maximum & will recommend a coil for that. Further, they & your instruction sheet will tell you NOT to power the EI unit by way of that resistive wire that SouNdguy spoke of.
 
When I installed EI in my 68 2000 I did not know about the resistor wire going to the coil.
The tractor was all original including the coil and wiring harness.
I did not change anything else.
It ran excellent.

re you saying that you powered the EI module AND the coil both through the resistor wire?
 
(quoted from post at 10:26:58 12/22/12) Yes.

So much for "modules won't work at reduced voltage". If you didn't know, maybe it didn't know either & the old saw, 'if you don't know it, it won't hurt" applies?
 
(quoted from post at 12:04:54 12/22/12) Check the resistance with a VOM. ~3.2 ohms will be a 12V coil and ~ 1.6 ohms will be a 6 V coil.

ot to disagree with anything you said here, but I would add a 3rd category........most 12v vehicles have coils that are less than 3 Ohms primary resistance and use a resistor or are EI or both, but will not be listed as "6v coils".
 
(quoted from post at 13:23:02 12/22/12) Thank you all gentlemen. I have a plan coming together !!!!!!

s your plan to supply the coil via the resistance wire & separately supply the module by another copper wire?
 
I bet you those 12v ones have a wider input voltage range than one may think.

say they are using 5v logic.( for arguments sake ) on a 6v system, that doesn't leave much play. on a 12v system.. they are golden. stick in a 7805 and go. input v can be 25v :) ( just for arguments sake.. I know they are not using a 7805, etc.. but same would apply for whatever device methodology to get 4a supply current. ( mind you.. with thermally protected 7805, , you could parallel 5 of them.. :) ;) )

A 6V EI will work at 4.5V no problem.... This does not mean I am push'n EI set ups on 6V guys what ever works for ya is good enuff for me... To answer his question If I were in doubt I would use a 6V coil with the proper resistor I can not see were he could go wrong...

I make this statement """ A EI set up suffers form the same issues a points set up suffers from""" Its hard to prove that statement wrong,,, a points guy with any experience trouble shooting can diagnose a simple EI set up once he gets over the skeer factor...

On a 12V EI with a 6V coil,,,,2 separate power feeds are not needed,,, feed the EI off the power source side at the resistor and feed the coil threw the resistor...

Y'all have a Merry Christmas

ot than I may think! I expect that all N's, pos gnd, neg gnd, 6v, 12v, front mount, side mount are all covered by two modules. Further I would not expect to find a voltage regulator in these simple modules. :lol:
 
I wasn't talking about you.. :) and no.. i don't think they have a monolithic vr module in there specifically either.. plenty of ways to handle wide range of inputs on chip.. etc.

I would have guessed 4 modules.

2 front, 2 side. one for positing gorund, one for negative ground each.

then again.. I've never seen the front mount module.. is it physically near same size as side?.

ifferent breaker plates & magnet ring in kit, but modules look same except wire colors for POS/NEG.
 
yep, I new the BP would be different. I guess if it's small enough to use trhe same mao no reason not to.

I believe the module in my farmall C would drop into one of my fords.. :) module anyway..
