Hi I have been fixing up a 1985 K100 for the past few months. Mostly its back together and it runs great, the only problem I have is with the indicators. We rewired and put new little ones on and they work when the Hazards are on but when you put the left or right indicator on they dont flash and the relay juzt buzzes. I have changed the relay twice with no joy. I have checked the control cables and it all seems fine. I think it might have something to do with the controls as the Hazards work.

Please let me know if you can help as this is basically the last thing before its raodworthy.

Cheers

You put on LEDS or mini lights with smaller bulbs? Either way the load on the flasher is significantly reduced so it flashes WAY faster, to the point where the signals look solid. Two solutions, one, replace the thermo style flasher with a generic solid state one or put additional load in the circuit by way of a resistor near the bulb, prolly around 5 - 7 ohms, you'd have to experiment.

I suspect club_c has nailed it as long as it worked OK previously to changing the bulbs over to LED's.

Have a look here for info on using LED's.
