Re: [FWDLK] Ballast Resister 1955 vs. 1956 Imperial

Jim,

The resistor is used to reduce the current to the coil not to reduce the
voltage. This helps the points to last longer. 12 volt cars use a 12 volt
coil, 6 volt cars use a 6 volt coil. The 1955 to 1958 parts book shows the
number for a 12 volt system resistor but only shows a package of coil and
resistor for the Imperial (1818 840). I will have to check, but I think the
resistance is different from 6 volt to 12 volt. Mopar did not use a coil
with an internal resistor in the 50's. If you do not use a resistor, you
will get a hotter spark ( good temporary cure for a weak coil ) but you
will burn up the points quickly. On 1957 and earlier Plymouths, the
resistor is mounted on the coil bracket. On the 1958 Plymouth, the resistor
is under the master cylinder on the mounting plate.

Will check on the resistance differences.
