1949 Ford 8N - 6 volt negative ground?

May I recommend you consider fact that improper grounding of your 1-terminal squarecan 4-nipple frontmount ignition coil can COST you upto -40% of your sparkie volts. The consequences of inproper grounding of your battery can be eazily corrected by changine the battery around and grounding the positive terminal and connecting the negative terminal to the 3-terminal starter solenoid. ...THEN... re-POLARIZE your voltage regulator/generator.

To re-polarize your electrical system to POSITIVE GROUND, simply "arc-spark" your voltage regulator BATT & ARM terminals on your squarecan voltage regulator under your oilpressuer gauge. The BATT & ARM terminals are side-by-side and connected to BIG heavy yellow wire. Ignore the other 2-skinny black wires. Simple, eh?

As for your enquiry about electronic ignition, despite the glowing endorsements of pleasure of electronic ignition users, please NOTICE that they are ALL running the 5-nipple sidemount distributor which has room for the drop-in module installation. Please notice you have a 4-nipple frontmount distributor which DOES NOT HAVE room for a module without major modification. Also notice they also admit to running a 12 volt conversion, which has to be negative ground because of the built-in solidstate voltage regulator inside the alternator.

So iff'n ya gotts yer little heart sett on electronic ignition then open your wallet for $150 for new distributor + $200 for 12 volt conversion + $200 for electronic module conversion.

Bottom line, you can change alotta $3 ignition points on your kitchen table for the braggin' rights of having electronic ignition..... ....respectfully, Dell a 12 volt advocate for the right reason and runs an electronic ignition on his 1969 BMW 2002 that he installed

THERE IS SOME QUESTION ABOUT RUNNING 6V E IGNITION IN COLD WEATHER WHICH WE DONT HAVE TO
WORRY ABOUT. I WOULD TALK TO DENNYS CARB ABOUT A E IGNTION FOR A FRONT MOUNT DIST. I AM RUNNING A 50 8N WITH SIDEMOUNT DIST. ELECTRONIC IGN AND 12V. ITS THE BEST EASY THING YOU CAN DO FOR AN OLD N. YOU CAN THEN CONCENTRATE ON ALL OF OTHER REQUIREMENTS OF AN OLD N. OF COURSE THE WHOLE WORLD SWITCHED TO 12V AND E IGNITION A LONG TIME AGO FOR GOOD REASONS. YOU WILL GET ALOT OF ADVICE. GOOD LUCK
