I have an Stratocaster iefis explorer lite paired to a rdac XF. Everything is operational except the rpm. When booting up a red X is displayed over the rpm area and no rpm is shown. I have moved the rpm lead to the old EIS display and rpm is shown accurately indicating an acceptable pulse. Does anyone have an idea as to a solution?
Thank you

On the RPM1 input?
Ballast OFF?
Adjust the sensitivity screw until you get a stable reading.

Red cross on RPM display area indicates that RDAC data is not received. Check RDAC CAN connection, and check that RPM display field is assigned to correct RDAC number
