• Before charging: only add distilled
water if fluid is below the top of the
plates, and then add just enough to
cover plates.
• After charging: open the vent
caps and look inside the fill
wells. Add distilled water until the
electrolyte level is 3 mm (1/8")
below the bottom of the fill well. A
piece of rubber can be used safely
as a dipstick to help determine this
level. Clean, replace and tighten all
vent caps.
NOTICE
Normal tap water contains
minerals which are harmful to a
battery; therefore, refill only with
distilled water.
3. Using a hydrometer, check the
specific gravity of the battery
fluid in each cell against the
readings on the chart below.
Consult a Yamaha dealer if any
low readings are found, or if
readings vary more than one
point between cells.
