check your charging system and load test battery
ANSWER by on August 31, 2013
HOW DOES YOUR BATTERY LOOK? ARE THE CABLE CLAMPS DIRTY OR CORRODED? ARE THE CLAMPS LOOSE? ALSO, CHECK THE OTHER END OF THE POSITIVE CABLE. IT GOES TO THE STARTER. BEST BET--CORRODED BATTERY CABLES. THE BATTERY MAY ALSO BE LOW ON WATER. HAVE YOUR BATTERY CHARGED AND TESTED. AND THAT MAY BE ALL YOU NEED. GOOD LUCK AND LET ME KNOW. THE FACT THAT IT WON'T START AFTER KEY OFF AND SEEMS BETTER AFTER SITTING DOES INDICATE A POSSIBLE PROBLEM IN THE CHARGING SYSTEM BUT BATTERY CLAMPS AND CABLES THAR ARE CORRODED CREATE RESISTANCE THAT CAN PREVENT THE ALTERNATOR FROM KEEPING A GOOD CHARGE ON THE BATTERY, AND MAKE SURE ALL CONNECTIONS ARE TIGHT SO HERE IS WHAT NEEDS TO BE DONE: CHECK FOR CORROSION AND IF PRESENT, CLEAN USING A MIXTURE OF 1 /4 CUP SODIUM BICARB (BAKING SODA) TO A GALLON OF WATER AND POUR SOME INTO A SPRAY BOTTLE TO USE TOGETHER WITH A METAL BRISTLE BRUSH IF CORROSION IS VERY BAD, YOU MAY HAVE TO REPLACE THE CLAMPS AND POSSIBLY CABLES--DEPENDS HOW LONG THE CORROSION WAS ATTACHED. IF IT HAS GOTTEN INTO THE CABLE ITSELF, IT MAY NEED TO BE TRIMMED OR REPLACED TO STOP THE CORRODING PROCESS.
