Battery charging condition can be checked by measuring battery terminal voltage with a digital voltmeter [A].

NOTICE
Be sure to disconnect the negative (–) cable first.
NOTE
Measure with a digital voltmeter which can be read one decimal place voltage.
If the reading is 12.8 V or more, refresh charge is not required, however, if the read is below the 12.8 V, refresh charge is required.
Battery Terminal Voltage Standard: 12.8 V or more
Terminal Voltage (V) [A] Battery Charge Rate (%) [B] Good [C] Refresh charge is required [D]

Cam Wear Inspection
Remove the camshafts (see Camshaft Removal).
Measure the height [A] of each cam with a micrometer.
If the cams are worn down past the service limit, replace
the camshaft.
