Have a old Police K100 rescued from a back garden in May. Been sat for five years. Its been recommissioned and just done 1100 miles around UK (never missed a beat on run). Tad fresh. However have an intermittent conk out/poor starting issue and now post run the fan comes on together with temp light. Having joined forum and read Bert's troubleshooting just wanted to say thanks to Bert and wider forum for all the brilliant tips and enthusiasm for what is a great machine. Will update when I have gone through the electrical guide, cleaned up everything and tested the Temp Sensor.

Hi and welcome to the madhouse, JM!

Your warning light/fan issue is often caused of a bad ground connection between frame and engine.

The frame lug close to the alternator acts as the main ground connection between frame/engine, if you remove the bolt...beware, as it could be a shim between the frame and engine.

Your poor starting issue could also be related to this bad ground connection.

Welcome. Before you get told off, put your model, year and frame number in your signature. This will aid the guys in answering any questions you may have. Also do an intro about yourself, a few more posts and you will get access to the download section - lots of info manuals etc. Also, take pics of your bike and post, we all like pics Very Happy

welcome jm

lets hope the issues you are experiencing turn out to be small ones.

things that you have mentioned should be easily rectified .

we have seen poor brush contacts in the starter motor as a matter of corse

poor battery and earth terminations to the frame etc ...

possibly best to try and isolate some of the issues and resolve them one at a time .

we find that our old girls need lots of anticorrosion cleaning to all sorts of places .

and "deoxit " comes highly recomended as solution cleaner and restorer of poor electrics

good luck

Welcome to the forum JM - pretty much anything you need to know about the old "K" can be found here somewhere - if not just ask Wink
