I don't know about having to remove the components with the red Xs.
RV2 isn't variable so should it have an R designation instead of the RV?

Quote: RV2 isn't variable so should it have an R designation instead of the RV? Well actually.... looking at it again, it would appear to be a cap, so it should have a C designation?
i did everything i was told, and the first time i hooked it up it worked,
This tach will work on the signal from the W terminal on the alternatorThe Bosch alternator that i used gave 6 pulses on the W terminal and the ratio between the cranck and the alternator is 1:2,38. When you calibrate it do it on the higest RPM possible you get a better reading on lover RPM:s.
I've just re-read though and it may seem that the 25 pulse per engine rev quoted elsewhere may be a little excessive and 14.3 is nearer the mark....
