    Has anyone ever experimented with conductive grease on the terminations on their high tension leads? Similar to the conducting medium used under Tens Machine pads.

    No, it would just provide an easier path for arcing. Di-electric grease to reduce/prevent corrosion is the only suitable grease for a secondary connection...as well as the vast majority of other electrical connections. Conductive grease has a few very specialized applications but it is not safe/suitable for general use in electrical connections.

    Mike would di-electric grease be suitable around the switch contacts of the turn signal stalk?

    I would say yes. Verell rebuilt mine and i seem to recall some grease

    I did some more reading on this and all the testing seems to indicate negative consequences of using conductive grease.

    And dielectric grease seems to have almost exclusively positive consequences. Thanks for putting me straight on my wild thoughts Mike.

    Glad I could help! Most of what I know about stuff is the result if screwing it up the first time (and sometimes the second and third time)! ;) On this subject, I use di-electric grease on virtually every electrical connection in cars/boats - Almost a requirement in the salt water boating world for reliable electrics

    I'm a big fan of using Deoxit Gold on electric contacts for keeping corrosion at bay and improved connection Far less messy than grease. Not cheap but worth it in my opinion

    I use deoxit extensively and agree it is an excellent product - despite its somewhat over-enthusiastic marketing hype! ;) I use it a lot on everything from restoring old vacuum tube (valve) gear to automotive/marine use . BUT, from personal experience, I can tell you that in the marine environment, Deoxit alone will not protect connections against corrosion. OTOH, cars don't operate in salt water so their electrical systems are generally not exposed to that level of "abuse." ;)

    If choosing to use grease: After the contacts/terminals are clean a coating of di-electric grease is applied to the contacts/terminals and then the connection is re-made. It's important that the grease is applied to the relevant contact surfaces BEFORE making the connection. IOW, physically making the connection is done "through" the grease. Di-electric grease has no effect on the circuit. It does not increase (or decrease) resistance of a properly made connection in any way.

    Why "Di-Electric" grease as opposed to, say, wheel bearing grease? Simply because di-electric grease is totally free of any conducting-capable ingredients. Other greases, depending on their composition, may have some conduction capability which could cause a problem in some situations.

    This is the type of grease Bosch used on the internals of the ignition switch contact block. Copper grease. I use it on all my battery connections and sliding electrical connections (turn signal). I use dielectric grease on connections subjected to a harsh environment after the connection is made.
