do you use contact cleaners? It depends. It is good to have some available but sometimes you need to get physical with a dirty even rusty connection. Wire brush, sandpaper. It depends on the situation. Greg

It depends on the situation. Greg Yes but in prevention, before they become dirty. For instance, once a year, you check each connector, they appear clean and you still put a bit of cleaner ? I wonder if I must buy the cleaner and do apply it to prevent arising problems.

for the most part, any sort of oily lubricant you can put onto 'spade' type connectors will slow down corrosion and failure of the connector. You can remove ground strap fasteners, clean the chassis(ground) and the terminal, put a dab of oil or grease on the connector and re-install it and likely have a good ground for a long time. If the connector is tight to the chassis, and lubed, it should make good contact, preventing moisture and dirt from coming between the chassis and the connector. If too loose, they can corrode more readily. Once cleaned and tightened appropriately, they should stay that way with little maintenance. tom

f the connector is tight to the chassis, and lubed, it should make good contact, preventing moisture and dirt from coming between the chassis and the connector. tom Yes I was thinking about this, for instance behind the rectifier: there is a screw to hold the rectifier to the frame of the scooter and I noticed that the black paint of the frame was removed around the hole of the frame; and there is brown crust there now. Same thing for the screw tightening the ignition coil to the frame near the spark plug. But if I put grease on this brown crust, will the current still pass through it [in other word, does grease conduct electricity?]. I have only lithium grease as non-spray grease, is this okay as lubricant?

The brown crust is likely rust, o Iron Oxide. A thin film of oil will slow down the corrosion, and will be displaced by the metal being squeezed together. I think grease would do the same thing. If I had corrosion, I'd clean it off using an abrasive, scotch brite, or steel wool, and clean the connector or rectifier/regulator mount, wipe lightly with oil, and reassemble. If it fits tightly, it should be ok, but will only stay corrosion free as long as the lube stays. You can use 'star' washers to increase the 'connectivity', but at risk of easier corrosive action. Maybe star washers, cleaned, no lube, followed by spray paint to seal out water. tom
