Hour Meter
The hour meter used on the ProCore 648 uses an induc•
tive pickup wire connected to the rear spark plug wire to
sense when the engine is running. The hour meter
should increase 1/10 of an hour every six (6) minutes of
engine running time.
The hour meter uses its own internal battery and there•
fore, is not connected to the ProCore 12 volt electrical
system. The hour meter battery is not replaceable.
