MAINTENANCE
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 1/8" (3 mm) below the bot-
tom 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.
