Title: Dielectric grease on connectors
Post by: Grahamm on 11 July 2020, 10:19:09 pm

I don't know about you, but I HATE those stupid plastic connectors which Yamaha has used to link multiple wires. Some you have to push down on a tab to release the catch, others you need to lift a tab *up* to release the catch...

But, whatever you have to do with them, they're an utter ba$$$$d to undo!  :wall :wall :wall


So, has anyone used dielectric grease on them to help them release more easily?


I know the grease is non-conductive, but, when you push two connectors together, the grease gets "scraped off" between the metal contacts to ensure there is continuity.

Would putting it on those plastic connectors be a good idea?

PS: No, I'm *not* going to use Vaseline - a) it degrades any rubber it comes into contact with, b) it melts when it gets hot and c) it's petroleum based, so could, theoretically catch fire!!  :eek

If you want to use something, use the correct stuff. Something like this is good but not entirely necessary as the contacts do not generally corrode to the point they cannot be undone.

Thanks for that.

The connectors can *eventually* be undone, but when I was trying to get the one off the start relay, I had to use screwdrivers and pliers to get it free :(

My brother's a "sparky" and gets me dielectric grease really cheap. I use it each time I undo any block connectors- it seals against ingress of moisture & prevents the pins furring up.
I do wonder if dielectric grease and silicone grease are the same thing?Rob
