I finishing putting new headlights, wiring, and switch on my 49 8N, and can now see in the dark when I need to drive the tractor in the dark. Something is puzzling me and need your expertise. This tractor has been converted to a 12 volt, one wire system using a GM alternator. I could not find a coil connected to the front mount distributor nor could I find a voltage regulator anywhere. I'm guessing, by reading previous posts, that the voltage regulator is built in to the alternator. Two questions: 1. Shouldn't there be a coil somewhere even in a 12 volt conversion? 2. How can I tell if the voltage regulator is built in to the alternator? Thanks in advance.

Izzy..... ..Your 1949 8N has a 1-terminal squarecan ignition coil is wirebailed clipped to the top of your 4-nipple frontmount distributor.

Iff'n you have a 1-wire Delco alternator, you most definately have a built-in voltage regulator. Besides being cheap, its the built-in voltage regulator that makes eather the 3-wire or 1-wire version Delco popular for conversion purposes. Just remember, it takes about 1800 rpms (3/4 throttle) to self-excite the 1-wire alternator. Once excited, it will charge at near idle.

You do know that its a 2-bolt 15 minute job to remove your frontmount distributor to change the points, don't you? Just unsnap the 4-nipple crabcap and letter dangle and unbolt the distributor and taker into the kitchen table and replace the points and gapp'em 0.015". While your setting at the table, gently stretch your coils thingy for more consistant contact with the points feedthru screw.

Re-installation is just as eazy, finger install the 2-bolts and rotate the rotor around until its off-set tangs drops into the camshaft drive slot. Then tighen the 2-bolts, and clippie the crabcap back on. Simple, eh? ..... ..... .Dell, a 12 volt advocate for the right reasons

Dell:

Thanks for the info. And, yes, by reading this forum am aware that the distributor is taken off for a tune up. Thanks for your help.

The black square coil sits ontop of your distributor cap..You should also have an inline resister going to the coil..
