Forgive me for posting instead of mailing. Your mailing address is
too long for my system to handle.

Sounds like the voltage regulator to me. The mechanical VR in your
Dodge is essentially an on-off switch that supplies 12V to the 
alternator windings when the voltage output is too low, and cuts the
juice off when the output is too high. Sounds like the relay sticks
to the high side when you suddenly pour on an extra load, like when
you turn on the lights. Get that thing fixed before it burns up your
electrical system. An unregulated alternator can put out several
times its nominal voltage when you are going at high RPM.
