Check the green wire behind the clocks is connected.. Has the bulb gone?

[Timmy]

all the connections wear solderd and its lite but its not showing the revs

[Connor]

check non of the solders have cracked

[auzzy-b]

Check your coil, I think it gets it's signal from there..

[swedge]

I just fitted mine and the revs work sometimes and not others, my wires are fine too and can't figure it out

the revs go up on the test

[auzzy-b]

Just trace your wires back mabye it's a dodgey earth or sensor?
