12V alt to use in convert with a dearborn loader?

joe in WI · Sep 30, 2009

hi all, the resistor fiber block is totally shot on my '47 8N. the voltage regulator (the mount rubber posts were shot long ago also) took a powder today. the generator is getting weak.i'm planning to convert to 12Volt. i know the Delco 10SI is the easiest to wire, but the 8N has a dearborn loader and the generator is VERY close to the tube, hence my concern about the diameter of the 10SI. i'd rather use a Ford alternator with the ford voltage regulator. salvage yard inventory is readily available.any pointers(make,model,years...convient mounts to convert)? also, the afore mentioned salvage yard has literally a thousand tractors, and is redicuously cheap on parts. any suggestions from someone who has "been there done that"? Thanks in advance...Joe

If it is size that you are concerned about, I don't think the standard Ford alternator buys you much there. Try Hitachi, Daihatsu, etc. for smaller diameter alternators.

A good rebuilder can convert your generator to 12v,then get him to sell or tell you the right regulator to use and that will eliminate the space issue.---lha

you can either tuck the 10si in real close.. I have one on my 2n that uses 2 small flat tabs as the lower mount to the TC, and a top bracket to the water pump.. this make sthe blet rub the distrib, so I added an idler pulley. if you search the pic archives on the left.. under parts/pieces.. you can see my pics.... that keeps the alt tucked high and close.

or you could use a delco cs 130 alt.. they are a smaller barrell.. and internally regulated.. just need 15-45 ohms on their excite line.

or a hitachi import alternator late 70's application and something like an old chrysler 'black box style' vreg ..

I found the pics for ya

Thanks for the pics soundguy..quite tidy! i'm trying to save the gen as 6V for a "someday" return to stock insted of having it converted. since salvage parts and fabrication is no problem for me, i figured aside for the cost of a new coil, i can convert to 12V for less than the cost of a new 6V regulator just to convert it anyway.even with everything set just right and with an engine heater, winters here can make starting the old gal a little tricky. thanks for the info!
