• Temperature conversion
specific gravity.
• Battery electrolyte specific gravity changes
based on temperature.
• Insert the value identified on a specific
gravity meter into the following conversion
equation for temperature correction to learn
an accurate specific gravity value. (Standard
temperature assumed to be 20 ℃ [68 ℉].)
D = D +0.0007 (t -20)
20 t
D = specific gravity value converted to

standard temperature of 20 ℃ (68 ℉)
D = measured specific gravity value at the

CAUTION
• To prevent an accidental short circuit, attach
the positive cable to the positive terminal before
the negative cable is attached to the negative
terminal.
• Do not remove the battery cap while the engine
operates.
• Keep electrolyte away from eyes, hands and
clothes.
If you are spattered with it, clean with water
immediately.
• Keep open sparks and flames away from the
battery at all times.
Hydrogen gas mixed with oxygen becomes very
explosive.
• Hold the starter to prevent its movement when
you do a test on the motor.

IMPORTANT
• Do not disconnect or remove the battery when
you operate engine.
NOTE
• B terminal: It is the terminal that connects the
cable from the battery to the starter.
• C terminal: It is the terminal that connects the
cable from the motor to the magnet switch.
Tools required
• Circuit tester
• Jumper lead
1. Disconnect the negative cable from the battery.
2. Disconnect the positive cable from the battery.
3. Disconnect the leads from the starter B terminal.
4. Remove the starter from the engine.
5. Connect a jumper lead from the starter C terminal
(1) to the battery positive terminal (2).
6. Connect a jumper lead momentarily between the
starter body and the battery negative terminal (3).
