Electrical System
SAFETY AND MAINTENANCE TIPS
Check battery connections periodically to make sure they are
corrosion free and TIGHT.
Alterations of any part of the wiring system should be avoided! Such
alterations could cause damage and/or electrical short.
Inspect wiring connections and terminals periodically for corrosion,
etc. and replace as needed. Replacement components should always
be of equal or greater rating and quality. We recommend Ranger
replacement parts available through your Ranger dealer.
Always disconnect the positive and negative leads from the battery
terminals before installing, removing, servicing, or troubleshooting
any part of the electrical system.
