996 SPS Replacement Tachometer Problem

[Sean K]

I am having to replace the clocks on my '99 996 SPS because of crash damage. I have recently bought a replacement set of clocks from ebay which look in great condition, everything works apart from the tachometer. The seller insists they were working when they came off his bike and I am lost as to why they will not work. I have changed the wiring loom off my old clocks and I still cant get tachometer to work. I know bike loom works because old clocks still work and register despite damage.

The clocks I have bought did not come from 996. Are there different tachometers or circuit boards inside Ducati clocks which may cause this problem?

The SPS with its P8 computer uses a different tacho to those found on bikes that use the 1.6m ECU such as the 748, 916BP and 996BP

Thanks - do you know what other Ducati's have P8 ECU?

Posted this in the other thread first but may as well add it here

P8s can be found on the
916 Strada (single injector)
916SP
916SPS
996SPS
also on Corse 955

888 also used the P8 but probably had a different design of tacho
