After having the engine replaced due to throwing a rod, the tachometer now reads zero when cold and about 250 rpm low after warming up. I've checked all the fuses and swapped out the ignitor since the schematic shows the ignitor supplying the signal. I've looked at all the engine harness wiring and can not find any discrepencies, the next thing may be to get the meter out and ring out all the wiring. The schematics I'm using are from the Haynes manual so I'm not sure they are entirely accurate. Where does the tach signal come from and where should I look next?
