Alan:
If you keep the 6V coil you will need a balast resistor between the ign. sw
and the coil. If you use a 12V coil, no resistor is needed. The factory 12V
systems of 55 and later used a 6V coil and balast resistor and eventually
(I don't remember the year) a resistance wire instead of the resistor. The
resistor was bypassed during starting by a wire running from the starter
solonoid -- or switch, in the case of the sixes prior to '60 -- to the
coil. That system gave a hotter spark during starting. I havn't found it
necessary to bypass the resistor. I typically run the starter till I see
some oil pressure before I turn on the ignition. Otherwise it starts too
fast and with no oil pressure.

purchase (kept the point distributor and changed to a 12V starter). Do I
need to run an external resistor with an external 12V coil? If so, does it
go between the starter bypass and the coil or the regular 12V feeder wire
(from the cab) and the coil? I've looked at the chevytrucks web site and
see no reference to what brand/type/size of resistor I would need. Can
anyone tell me? Thanks for the h_e_l_p.
