Lights stay on when ignition switch in Off, bike won't start

It looks like beefing up these grounds should be a pretty standard modification to a ST1300 - am I right?

My ground cap looked exactly like the one in post 89. Ran a thick green wire to the bike frame from the yellow ground cap and the problem has never reoccured.

Ref Post 65 - YIKES! Connectors shouldn't burn up like that! I'll try to keep my eye out for similar symptoms. Thanks for posting the solution and all the other findings.

It's not just the ST. A short while ago I sold my CBR1100XX,...............look up " Loom Fix ". You'll find that Honda had put in a factory multipin ground test port so they could check the functions of all the circuits while on the Dyno at the factory, then just wrapped it with electrical tape. It's under the seat next to the seat subframe. No water there now is there? All kinds of FI issues. Now I also see Honda has a similar plug behind the throttle bodies. Nobody has corrosion issues with this one?
