Ignition switch cleaning 84 GL1200

[vrocrider]

Problem: ignition switch cutting off sporadically. Proposed solution: clean contacts. How do you do this?

Solution update.
Remove key switch from bike. Remove plastic cover held on by 3 tabs from back of switch by pressing tabs in with small screwdriver. Remove electrical housing from metal key housing. Mark position of white plastic base with felt pin. Pry apart electrical housing which exposes 3 movable contact plates with total of 4 springs behind movable plates. Each plate has multiple contact points. Base has multiple fixed contact points that movable plates touch as switch is turned.

Clean all contact points with electrical contact cleaner. Work oil stone and/or 400 wet sandpaper on all damaged fixed and movable contact points. After final cleaning with contact cleaner apply small amount of dielectric grease and reassemble.

Use electrical tape to seal metal key housing and plastic cover. Connect ignition switch to bike wiring and operate to check proper operation prior to installation.
