    Dielectric Grease or not?

    Installing a new voltage regulator on my 03 XP DI. The old plug connections clearly have some type of grease on them to prevent corrosion. I would think that Dow #4 or any dielectric grease would be fine. Dielectric is an insulator rather than a conductor, but is the grease of choice in these applications. The shop manual does not mention or display the use of a grease at the terminal, but its there...….

    What do you ever knowledgeable forum folks say?

    Dielectric grease is not an insulator and should not be used as one. you can use your volt meter to confirm this. it has high resistance but will conduct electricity and burn.

    I've used synthetic bulb grease or dielectric grease on electrical connections to keep corrosion at bay for over 20 years. Never had an ill experience using it.

    If used correctly it make a great corrosion resistance connection.

    At what voltages are you making this statement?

    Dielectric grease (silicone) should not conduct or burn unless there is an arc gap present and the voltages are high enough to bridge the gap.

    For 12 volt type connections and generally for voltages well under 50 volts with solid metal to metal contact within each mating pin/socket, there should be no arcing and no conductivity attributable to the dielectric grease.

    Dielectric grease does not enhance nor degrade electrical connections. It is there mostly to occupy the void spaces and displace potential air and moisture exposure of the contact surfaces.

    If the ‘dry’ contact connection would work just fine without any dielectric grease, it should also be just fine with a coating of dielectric grease. The difference is that over time the grease should prevent the contact/pin corrosion that moisture and air exposure can cause without the grease.

    Contacts and connectors carrying high voltages and/or subject to contact arcing are a different thing.

    be careful to only coat the connections, filling a connector with it will cause unwanted problems
