Got a tacho problem - any advice on this?

Rotax 503 with dual ignition, Falcon Tacho - cables = grey to ground.

1) Installed guage with small white cable clipped as per Falcom instructions for dual ignition engines. Got double count reading = 4000 at idle, off the scale with a bit of gas, returns to 4000 on idle. Concluded that small white cable should not be clipped after all and reconnected it.

With the small white cable connected I get:

2) Start engine, 4000 revs. With a bit of gas, goes off the scale as per 1) but this time it stays there and refuses to return to 4000 on idle.

Any ideas?

Mine is wired the same, grey to tacho and tacho to ground the other.

Maybe it's broken, send it back for a new one.
