Title: No Power to Dash/Clocks/lights on K5
Post by: Sean T'sheep on Tuesday, 24 August 2021, 04:43 AM
Rode home from work as normal this afternoon all fine. Went out this evening, started her up to have an evening spin but there is nothing electrical working other that the starter, ignition antenna and main and dip beam. No horn,indicators, rear light, brake light, dash indicators, speedo, rev counter or clock lights. Engine starts and runs fine.

Any one had similar issues? Really need to fix quick as meant to be going abroad on it next month

Tried the obvious, fuses, clutch switch, connection blocks etc

Any clues/pointers gratefully received

Have a good look at the loom .
Also might be worth taking the headlight off and give the wires a waggle to see if something is lose .
Sounds like ignition wires or power feed to the clocks
Good luck  :cheers:

And while you´re at this , also in the headlight, check for possible corroded connectors. Happened to me. Sometimes just 1 or 2 pins that you barely notice are isolated due to the corrosion; or even just hanging by just 1 wire.

Update. Found blown 15 amp fuse in the fuse box. Replaced and everything is now working except the indicators and brake light from the front lever.

Good you have most things working, sounds to me like a rubbed through wire & it's shorting out (blowing the fuse)  I'd be looking at the wires of the things that are not working to locate the issue.  Also where the wires go into the headlight bowl, as mentioned.

Final update: It was a shitty aftermarket flasher relay that had been plumbed into the wiring loom that was causing all the problems. It was shorting out,  removed it and reconnected wires to original flasher unit and all is well  :)

Brake light problem was bad connection on switch.
