Reply To: MEP-806B 50HZ / 60 HZ

Were using a tach to gain correct speed while adjust the fuel injection pump – stanadyne. I can get the motor up to 1800 rpms, 120/20860 hz. The problem is the CIM disply does not go over 52 hertz. If I use a VOM to measure hertz at a load terminal, my vom says its 60 hz. cim not displaying correct hertz. Removed magnetic pick up sensor, cleaned and tested – ok. re-installed and adjusted to 1-1.5vac. no problem there.
