I want to locate and clean all electrical connectors and particularly ground connectors as I heard they are often the culprit regarding a no start condition.  Can anyone tell me where all the possible ground connections and connectors are on this bike?  thanks.  1985 K100 RT

l/h and r/h switches (one external wire each screwed to the metal part of the switch), on the frame near the ICU and the battery earth. I think that's all for the frame connectors, but if you're talking about the electrical block connectors too then you'll need to pull every one (including lifting the relays and unscrewing the relay blocks) and search for a brown wire. The wiring diagram will help with this.
