Help needed: Rev counter wiring

[RobStan]

Hi

I've had a little time in the garage these past few weeks and managed to fix some of the mess that is the wiring. However I've come up against a problem with the rev counter. Can some one tell me what should be wired to what on the back of my smiths RVI 2430/00A?





As long as I've had the car this hasn't been wired in, and before I go ahead and guess I thought some one here would be able to advise me.

Cheers
Rob

Cheers Adrian!

Just one question

"2 10 amp lucar blade/eyelet, Earth - black" where is this? do I just need to earth the casing or something else?

Thanks again
Rob

Hi Rob,
Yes there should be a minor 10 amp connection onto the back of the tacho....but they fall off, a earth should be loose there, add that to the fixing bracket if it is hanging loose.
