Speed control moving contacts treatment?
I have a Vintage Cushman three wheel golf cart with the moving contact speed control. I am replacing the burned contacts and coil resistors with new. Should I use any treatment on the moving and fixed copper contacts? Conductive grease, graphite, DeOxit?
Thanks in advance, Tom |

Re: Speed control moving contacts treatment?
Thanks Golf Cart Guy,
Vaseline sounds good, but it's low melting point (probably 90 degrees F) makes me wonder if it's the best solution. I expect the flowing current and heat from the power resistors to warm the copper conducting plates somewhat above that. I think I need something with a higher melting temp. Vaseline makes good sense for corrosion prevention though. I'm more concerned about helping the moveable contact slide smoothy and easily across the fixed copper plates. I understand that the plates must be aligned flat to each other. |

Thank you, dielectric grease it is.

Re: Speed control moving contacts treatment?
I've read the dieletric grease will stop the current. Do this work well?

Re: Speed control moving contacts treatment?
It sure does. Unless I read it wrong the OP was trying to smooth out some moving parts. If using conductive grease like carbon conductive grease, you have the potential to electricly bridge a gap with grease. I wouldn't think that's a good thing in any type of a control box, but I could be wrong.
