Relays are usually marked with paint blobs next to the terminals so you get them right.(well Honda ones are) Yours sounds like it's a power problem, the grey wire seems to be working as it should but the black wire doesn't. Try removing the black wire and testing it for voltage, or run a wire from the battery to the black terminal on the relay and see if that works, if so then it's a black wire problem, could be a dirty connection or a broken wire. If not the black do the same with the grey.

Electrics are easy, I kinda like doing them, it's just having a logical approach and persevering. It's when it goes internal on generators etc that I lose interest. Wiring though, I quite like.

Try connecting the two wires at the relay together with a jumper and see if the bulbs light up when switch moved, if so problem is flasher relay, if not wiring is faulty

Am I correct in assuming that when you move the indicator switch to say the left position that both left bulbs illuminate but do not flash on & off?
If so I think it must be related to your flasher relay.

Thanks Brian I'll give that a try tomorrow.
Ted I have used 2 relays , both new and different makes with the same result.

Yes but are they the correct part you have fitted?

As someone here has posted earlier if you bridge those two wires (not the earth) can you make them flash on and off by breaking and making the connection the connection? If it's yes you know where the answer lies. I'm not great with electrics and have no idea how a two terminal flasher really works but it does.

Well at last all is well.
I gave up on the 2 flasher units I bought, one on eBay and one from a local motor factors, (Lucas for M/C)
got a NOS Honda one from a mate , all is well going for a ride later.
Thanks for all of your input.

Would be useful to know the part number if you have it for future reference Rich my relay has been replaced with a two connector type that does not fit the (broken) rectangular suspension rubber.

38300-323-009 Ted. Rubber mount, round type is 38306-323-000

There is an alternative used in the US market, where we got a round relay they got a oblong or square one, rubber mount is then square, 38306-107-670 and the square relay, 2 pin version is now 38301-KJ6-741/2/3
