Checking and Filling
-Before work is done on the electrical sys
tem, disconnect the negative ground cable .
- Before performing any work on the electri
cal system, switch off the engine and igni

- Never charge a frozen or a thawed-out bat
tery. It could explode! If a battery has fro
zen, then it must be replaced. A discharged
battery can freeze over at 32°F (0°C) .
- Make sure the vent hose is always attached
to the opening on the side of the battery.
- Never use batteries which are damaged.
There is the danger of an explosion! Always
replace a damaged battery.
