Grounding an Ignition control module!

[Gpaw44]

Brain storming to make the ignition modules last longer! While resurching this age old problem to the C-10s I came across this quote from a previous post and it got me to thinking.
"Ignition modules do have intermittent come and go faults. just keep in mind that these things need a full 12 volts supplied and a good ground to operate properly. They need the chassis ground path before the power is applied.Jun 26, 2015"
I also viewied a vedio where the person mentioned that the gasket that is between the base of the distrbuctor and the block could impeed the flow of current to a ground.
With this thought in mind, why not add an external ground wire to the top side of ignition module attached to the screw closest where the wire comes out of the distributor and take it to a ground.
Some of MSD modules come with a ground wire attached internally and you take it to a ground..
I would like to know if adding an external ground wire to my "NEW" I.M. will it damage it out before I try it. Any thoughts?

An additional ground strap shouldn't hurt or negatively affect the module. FWIW, I've taken GM modules & aftermarket units apart before & those offshore brands have fewer capacitors & transistors in them. Same goes for the "brain" on Mopar & Ford vehicles. You can actually feel the weight difference also.

Thanks Strick It was also mentioned while resurching this topic quality control is not what it used to be. Suppliers receive what is produced off shore and then pass it along to the consumer to deal with!

A ground wouldn't hurt, but the distributor clamp grounds it to the intake. Bolts ground the intake to the heads, and again to the block.

I thought I had a problem with my ignition module ground - I put a small ring terminal on a length of wire, put that under one of the distributor cap screws (mine has the type of cap that screws down not just half turn) after confirming the continuity of grounding to that point, and then put the other end under a second nut placed over a cleaned intake stud. Didn't hurt anything, but didn't really help either.

Good observation G, but why does MSD put a ground wire on some of their modules? Could the heat sheilding grease cause intermittent come and go faults ispecaily if the threads on the screws are covered with grease going into the base of the distributor?

Are not most distrubutors aluminum?

Aluminum is still conductive. I believe the MSD modules with extra grounds have extra functions that require more stability.
