11. Programming for TACH / Voltage Sense
Programming for Tach
If the Alternator/Tachometer input wire is connected to the Tach wire (negative side of
the coil), you must perform the steps below. It is best to perform the programming after
the engine has been given some time to warm up and the RPM level has stabilized at its
normal position. Failure to warm up the engine and allow the RPM to stabilize may result
in later problems starting from remote control . NOTE: The alternator/Tach wire MUST be
connected AS PER PAGE 19 for the unit to properly function.
