" 1 Terminals
2 Hold−down clamp
Check the battery for corroded or loose connections,
cracks, or loose hold−down clamps.
1. If the battery is corroded, wash it off with a solution of warm
water and baking soda. Coat the terminals with grease to
prevent further corrosion.
2. If the connections are loose, tighten the clamp bolts − but do
not overtighten.
3. Tighten the hold−down clamp only enough to keep the
battery firmly in place. Overtightening may damage the battery
case.
