Motorcycle Repair: Blinkers, poor conductivity, circuit conductors

Question
I have a question concerning the blinkers on my 1971 Honda CB350E.
When I first start the bike everyday, they will not blink at all. They come on, but will not blink. After I ride it for a while, they will blink but very slowly-maybe once every 5-8 seconds. I put a new battery in several years ago,
but I remember it was the same then. Does it have a blinker switch to replace (besides the one on the handle bars ) or fuse? Any ideas on how to get them blinking faster?
Thanks Rodney


Answer
Hi Rodney,

The usual causes for blinkers to work as described are: poor conductivity through circuit conductors, connectors, and components due to corrosion or wear; and weak or defective charging system.

If the blink rate increases (inproves) with engine rpm, check the battery and charging system.

You may try replacing the blinker relay. The switch contacts may need to be dressed (cleaned), but I doubt it needs replacement.

The circuit protection is working because the system is illuminating. If the circuit fuse was defective, the lights would not work.

Ask Expert Bill Silver if he has any advice and resources for 35 year old Honda parts.
