Today was dry enough, I took the Goblin for a drive, to test the intermittent dash issue. The dash didn't work for the last 3 or 4 drives, but it worked today! I think just taking apart the electrical connector did it.
So I am going to blow out the connectors with compressed air, wash them in brake cleaner, and put dielectric grease on them.
Maybe that will keep the dust from my driveway from getting in between the connector contacts.
Update:
Dielectric grease is non conductive grease and should never be used on the metal part of the connectors.
Update my last update:
Yes, dielectric grease is non conductive, but you can go ahead and use it. Electricity will travel thru the metal to metal contact.
The dielectric grease can keep water out, but it does attract dirt... so it is a trade off.
I used compressed air to clean the connectors, then used dielectric grease on them. When the grease gets dirty, I guess I will wash it with contact cleaner/electric cleaner... the compressed can of liquid that evaporates into the air.
