ok, back from a few days R&R.
For those who wanted to source Termin8tr:
In Canada, Traction Heavy Duty Parts (NAPA's heavy division) carries the product, either on the shelf or they can order it from their catalogue.
In the US, at this time, you can only order by the case, a case has...darn, 12 cans maybe? anyway, contact Spectra directly, ask for Andy, he's expecting a few calls. Here's the link again:http://www.spectra-ssa.com/inforequest.html
I'm still friends with everyone!
The spray I use, Termin8tr, is a penetrating spray and a corrosion inhibitor and is dielectric. There are others, Fluid Film is another I have used.
Sprayed into wiring and connectors, it creeps up the wires, prevents corrosion, frees stuck parts, etc etc.
The trouble with dielectric grease, its effectiveness is local to where it was applied, and it is completely dependent on the efforts of the person applying it to get it deep into the sockets, or not. Air pockets prevent it touching the deepest parts of some styles of connectors. Dielectric grease will not defend against the creeping green or black death running down the conductors. The spray creeps down the cables, inside the insulation.
The busnut challenge moving ever deeper into the world of electronic controls, is keeping corrosion from walking up the conductors inside the insulation from the ends.
