BATTERY
• The MF battery used in this vehicle does not require mainte-
nance as inspection of electrolyte level and replenishment of water.
• No hydrogen gas is produced during normal charging of the bat-
tery, but such gas may be produced when it is overcharged. There-
fore, do not bring fire near the battery while it is being charged.
• Note that the charging system for the MF battery is different
from that of an ordinary battery. Do not replace with an ordi-
nary battery.
CONNECTING BATTERY
• When disconnecting terminals from the battery for disassembly
or servicing, be sure to disconnect the negative (-) terminal first.
• When connecting terminals to the battery, be sure to connect
the positive (+) terminal first.
• If the terminal is found corroded, remove the battery, pour
warm water over it and clean with a wire brush.
• Upon completion of connection, apply grease lightly.
• Put a cover over the positive (+) terminal.
WIRING PROCEDURE
• Route the wire harness properly according to "WIRE HAR-
NESS ROUTING". (!7-10)
USING MULTI CIRCUIT TESTER
• Use the Suzuki multi-circuit tester (09900-25008).
• Use well-charged batteries in the tester.
• Be sure to set the tester to the correct testing range.
Using the tester
• Incorrectly connecting the + and - probes may cause the
inside of the tester to burnout.
• If the voltage and current are not known, make measurements
using the highest range.
• When measuring the resistance with the multi-circuit tester,
also measure the resistance with no-load. Sub-tract that re-
sistance from the resistance measured under load in order to
get the true resistance.

resistance resistance
• When measuring the resistance with the multi-circuit tester, ∞
becomes 10.00 MΩ and "1" flashes in the display.
• Check that no voltage is applied before making the measure-
ment. If voltage is applied, the tester may be damaged.
• After using the tester, turn the power off.
" 09900-25008: Multi-circuit tester
NOTE:
* When connecting the multi circuit tester, install fine copper wires
(O.D is below 0.5 mm) to the back side of the lead wire cou-
pler and connect the probes of tester to them.
* Use a fine copper wire, the outer diameter being below 0.5
mm, to prevent the rubber of the water proof coupler from
damage.
