Re: [Chrysler300] Dual-Point Distributor not Distributing!

[Bill Huff <czbill@xxxxxxxxxx>]

Are you checking the spark by manually opening the points 
individually or by cranking the engine?  I believe there is an 
overlap in the points position so that one is responsible for opening 
and the other for closing the circuit.  Cranking may not show a spark 
at both.  Unless you are using one of the old Mallory 4 lobe 
distributors either set of points should run the engine just 
fine.  You might have to block one set of point open to check the other set.

Grounds spring to mind, make sure the coil has a good ground and make 
sure the distributor has a good ground.  I usually make sure the 
clamp has bare metal under the clamping area and that the bolt head 
has bare metal under it.  There is a flexible wire that connect the 
points under the breaker plate, it sometimes breaks or shorts.  Check 
the wire from the coil negative for continuity.  That's all that 
springs to mind at this time.  Of course, easiest of all is to try a 
known good distributor, but that isn't always possible.
