there is nothing wrong with the operation of the duraspark control module
until it die's. Here in Calif for 2 years at least it calls for a "red" relief block
not, blue, brown. I'm no GM fan but since my car's are pre-smog, the 62 Ford
and the 74 Dart, I went to the simple gm module, 4 wires done. This is not
a module in the roto-cap, I placed my on the fender well in the Dart and
under the Dist on my Cleveland. One guy has it attached to the underside
of the Chrysler Dist, there are mounting holes there. I don't like that because
you then need to remove the Dist to get the module out.
and you can keep a spare very easily since the unit is so small.
here in Calif you car back to 75 is subject to smog laws, which is the most
stupid law there is. I won't go into all the "crap" this state does.
Hey this is just my opinion. and I have a "red" duraspark box for sale if anyone
needs one... $$$ I've never even seen one in the wrecking yard...(red relief)
