1985 K100RS Left turn signal activation makes all 4 signals flash
The title says it all-when I activate the left turn signal all 4 signals flash while the right side does as it should.
I have cleaned both left and right switches with electrical contact cleaner and checked the relay box itself (61311459224), with no visible problems on either of the relays, though I did run some fine grit sandpaper across each of the contacts. Each opens and closes to the same degree.
I have checked and changed all turn signal bulbs and disconnected the 4-way flasher switch, all to no avail.
When the problem started, it was an intermittent problem; sometimes working correctly and at other times all 4 flashing. Now I can count on it to reliably flash on all 4 when the left turn signal is activated.
I have wondered if the relay is defective but am reluctant to start replacing parts.
Help is appreciated!
