'53 SC: another question about 12V/dist conversion

DennisT · Oct 9, 2012

Thanks to this forum, I've got the idea about timing, etc., when I install my Delco 1111411 right-angle drive distributor on my 1953 SC. Since my tractor has the old generator and I'm committing myself to the distributor ignition, I'm thinking of just going straight on to full 12V conversion with alternator. (1. Will my Delco distributor handle 12 volts? (I'm not sure if these came from the 6V days or later, so better ask)

2. Does anyone have a schematic or electrical drawing for what I need to end up with for full 12V conversion? I have heard that the one-wire alternators are not the best for low rpm/fast charging.

Thanks,
Dennis

There should be no problem using your distributor with 12V. The only problem would be with the coil. You need to make sure that you have a 12V coil, or that you use a ballast resistor with a 6V coil.

Thanks. That's what I was hoping for. I know I can find a 12V coil around here.

Until I build an alternator bracket and prepare to rewire all lights, etc., I might just run a start/run ckt. for now, and expand it all in the Spring. Maybe just positive battery-fuse-ignition switch-start button and on to coil.

Also, all of the SCs and DCs were negative ground from the factory, so your conversion will be easier than most.

All you need, ignition wise is a ballast resistor from a 1980's dodge. You can use the coil you have. The resistor drops the voltage down to your ignition.

Did you look at the articles under Research and Info. on this web site? Under the topic of "Maintenance, Mechanical and How-To Information" there are several articles on 6V to 12V conversions.

Unless I am wrong you are replacing a Mag with the distributor setup, you will need a coil and if you are buying one why complicate things by buying a 6V and then needing a resistor to drop the voltage, right up front buy a 12 volt coil, sometimes labeled with internal resistor. All that is necessary is that the coil have appx. 4 ohms primary resistance. Hook the coil up the same polarity as your battery, If you are installing an alternator, NEG ground is the norm, - post on the coil to the post on the distributor. I have done dozens and it is so simple a cave man can do it, lol

A Delco alt. will fit right where the old gen. mounted without ANY aftermarket mounting brackets whatsoever; using an aftermarket bracket will just complicate things. Also, an orginal type (7/8") belt pulley will easily fit.

I sorry, I dont' seem to see this topic on this website...Research and info....that is...
