Hi Derek here, I guess ill be the born again biker at 59 years with a Honda pan st1300 which I am struggling with at the moment trying to find a bad earth connection with zero success. There's a lot more wiring and bits too the bikes nowadays than when I was a lad. Like I spent an hour just getting the Tupperware off but hopefully get back on the road soon. Planning the North coast 500 this summer. Cheers.

Sorry Mark I posted another message which you can delete please,
The pan starts and runs fine until I switch on the lights then she cuts out and the lights won't go off until I disconnect the battery at that point I can hear a relay disconnect,
I reconnect the battery and she starts and runs fine again. Can see no bad or burnt connections. ????

No problem... I will paste my replies to your other thread in here, just in case they are helpful:

I'm not good with electrics I'm afraid but found this on the internet if you haven't already tried this method?

"place one of the multimeter (on resistance/Ohms setting, with the battery DISCONNECTED) probes on a grounded point (frame, though the best option is the negative terminal on the battery if your wires will reach). Then, using the other probe, begin probing wires/connections/etc. If you find a wire that has shorted to ground it will show a very low resistance (usually a 0 on the display)."

Found this too which has some wiring diagrams that might be helpful http://www.calsci.com/motorcycleinfo/ST1300_c.html

welcome. Have a good look around the headstock - well known for breakages there, and trace every wiring loom plug junction under the massive fairings and spray with switch cleaner (maplins). Then wok them well- look for nasty green corrosion..... you may need to do further by-passing of those plugs badly affected by the green death...........

You can also add a few new ones from the battery earth to the loom at various places - it will probably by-pass the problem for you... Good luck!
Life is a series of ever-faster bike journeys - as time begins to run out. But, I'm not finished yet...

Thanks guys, I'll have another bash at it this weekend and think I'll fit some new ones as Toast suggests.

Aberdeenshire, the best shire in the best country on our planet 
But in saying that, things are also great the further west and north you ride
I like riding, I also like bikes.
