stop lamp flashing

[baz]

does anyone know why the red stop lamp on the rev counter keeps flashing all the time even though the brake light works fine

Have you added a led bulb to either the idoit or tail light?

[baz]

no pal
for some unknown reason it just started flashing today

[warren3200gt]

They flash when brake light bulb blows, so are you sure rear brake light works . Might have itermitent conection somewhere in that section of loom.

I know and ive even changed the bulb just in case, the break lights perfect. it flashes from the moment you turn the key....is that correct or should it just come on when the break is applied

Baz,
Try another relay.

It should only flash if it "thinks" the bulb has blown.
The idiot light should only illuminate when the brake is applied.
The fact that its flashing means the little box of tricks is working. If it were not it wouldnt flash even if the bulb were blown.
What happens to the idiot light if you remove the tail bulb and turn ignition on? It should flash. It measures the resistance in the circuit. If the resistance is too high i.e. blown bulb or not fitted, it triggers.
You can try another unit, if you can find or borrow one but I suspect it'll behave the same. Or you can disconnect and do away with the safety feature.

Davidz1r had some nos units forsale a year or two back but i suspect he sold them all pretty quickly. Even unknown to be good units on ebay ask stupid money for what they are.

I'll try it with no bulb....thanks warren

[warren3200gt]

Baz, a dirty connection or rusty bulb holder increases the resistance, maybe over the units threshold.

[baz]

just tried it with no bulb and it still flashes

[warren3200gt]

Good, shows unit is working. Now try reverse, bulb in, unit disconnect. If it still flashes then, god know whats happening.

It should be attached by a rubber sleeve, under the fuel tank close to the two ignition coils, left hand side. I think you should be able to see it if you look under the tank, between the top of the motor.
I think there's a short loom to it with a small white 3-pin plug, although it might be a 2-pin plug.

[warren3200gt]

Or if its a 650 it'll be on the backside of the electrics plate under the left side panel.

result.....unplugged the relay and it gone out.......I take it thats the problem then
