Pertronix and plug wires

[George Lollar]

Pertronix in its installation instructions says with emphasis not to use solid plug wires with their system.  I believe this is in conflict with our recommendations to use solid copper non-resistant leads; what have 113 owners done with this?  What are the consequences of ignoring this instruction?

Not much that I know of. 560SLès use electronic ignition and solid wire cables. You can run into radio interference with systems MDS systems using high voltage but our cars use relatively low voltage systems.

I have Pertronix in my 1970 280 SL and have recently had problems with one or two cylinders not firing.

I have been using the Bosch spark plug wires that were appropriate for my car with the standard ignition and didn’t switch to the Pertronix recommended wires, but I am now wondering if this might have been a mistake.

Perhaps my misfiring cylinder can be attributed to having not changed the spark plug wires?
