Koso gauge RPM set up
DomP:
Sadly setting 4 made no difference, only getting a reading when I raise the revs
Bryanj:
1 rpm per 2 signals should be correct i think

That's what I initially thought Bryan, more research needed I think. At least I've got it to register some sort of reading
DomP:
Bring up my old thread as the weather has returned me to tinkering in the garage again, this time I'm determined to sort the rpm signal to my Koso gauge. I've been in conversation with the europe help desk and this is what they have told me is an alternative set up as neither of their other suggestions work. The question is are they suggesting I connect to one of the three yellow wires coming from the alternator? That seems like a recipe for a burned our gauge to me.
K2-K6:
Looks as you understand it, taking a signal from one of the phases of alternator.
This is quite usual though as many cars run that type. Most diesels with rev counters too as there was no ignition to read when they were less sophisticated. Many types have moved to running off crank sensor now and via ecu processor.
If that's their stated instructions it should be OK to try with their unit.
