GTS Rev counter wiring

[GTSPhil]

Hi Guys

I have a GTS cluster that has a newish printed circuit, yet this did not solve my rev counter problem. The rev counter is not working at all.

I am using an electronic ignition kit (Accuspark).

I am using the white wire with the black tracer from the negative on the coil to the back of the rev counter.

Then from the voltage stabilizer on the B connector (I think) a wire is run to the spade connector on the back of the rev counter.

The rev counter is the RCV type 12 volt negative earth.

Any ideas or proper wiring/ diagram will be highly appreciated.

Thanks

According to this wiring diagram (Its the same tacho connection for all the diagrams with voltage stabilizer) you should connect direct to a 12v line. 
I had endless problems with accuspark and aftermarket tacho, which were eventually solved by putting a 'floating earth' on the w/b input line, but its unlikely you will need this with an original unit
