We have a powercore series controller using a magnetic pickup for our speed source but we are not getting accurate reading. What could the issue be?
The most common solution for this issue is that the magnetic pickup could be dirty. Remove the magnetic pickup to wipe down and install back on the engine.
The other solution will be to confirm the settings within the powercore controller are set properly. (Ex. Speed Source, Speed Calibration - Pulse Count and Speed Calibration - RPM
How do we calibrate our tachometers?
You can adjust calibration on all models with the calibration button on the back of
the housing. The engine must be running at a known RPM during the calibration
Process. Once the tachometer is in calibration mode, it will exit the calibration mode
and return to normal operating mode if the calibration button is not pressed for 5 seconds.
How to reset service reminders on the Powercore controllers?
To reset service reminders press the menu key enter the passcode 3482. From there follow these steps.
System → Service Reminders → Reset All or reset the specified service( Ex. Oil Life)
