Ive a 1972 CB750 (located in Australia) which Im restoring after 20 years of storage. I have the motor up to working order and have started on the electrics.
The Blinkers were not working. Replaced some globes, found some loose wires/connectors, and hey presto Ive got working indicators. They do take around 1 second to start working, but then work correctly. I assumed this slow start was due to the low current, as I was working on the bike without the engine running for sometime and assumed the battery (recently replaced) had lost some volts.
So then I start the bike, and what do you know, the indicators do not work at all. Turn the engine off and the blinkers work again.
I can not work out the logic of why the indicators will work whist the engine is not running, and then stop when it is running. The only factor that would change ( I beleive) when the motor is running is that there will be more charge in the battery/circuit.
So I assumed a problem in the winker unit. I got a new unit from my local Honda dealer. Unfortunately, everytime I conect the new winker unit, I blow a fuse. I now suspect I do not have the correct, replacement winker unit. Unfortunately the original winker unit on my bike (which does work when the bike is not running), does not have any indication as to its sepcifications (no volts, watts, amps, manufacturer etc.). It is a nice looking aluminium barrell with three wiring pins sticking out the top.
Therefore two questions:
1) if anyone has theroies on why the indicators work when the motor is not running, then cease to work when the motor is running, Id appreciate your thoughts.
2) If anyone has a similar model bike, I would appreciate it if you could give me the specifications for the winker unit, so I can purchase a replacement.
thankyou in advance.
