Is there a problem with the electrical or my battery?

THE 1ST THING I WOULD DO IS TAKE IT TO A POPULAR AUTO PARTS STORE AND HAVE THE BATTERY AND CHARGING SYSTEM TESTED TO THE FULLEST EXTENT....THEY WILL USUALLY DO THIS FOR FREE!

THEY MAY FIND YOU HAVE A BAD BATTERY OR THE ALTERNATOR IS NOT CHARGING IT BACK UP......FOR SOME REASON (BAD ALTERNATOR, BLOWN FUSES, BLOWN FUSIBLE LINK, LOOSE WIRE, ETC). I SAW THE FUSIBLE LINK THING, DAYS AGO, WHERE MY WIFE WORKS. TWO EMPLOYEES SORTA DID NOT HOOK "+" TO "+" AND "-" TO "-" WHEN THEY "ATTEMPTED" A JUMP-START....KINDA KILLED EVERYTHING

IF YOUR CHECK ENGINE LIGHT IS ON---THE AUTO STORE MAY ALSO BE ABLE TO READ THE TROUBLE CODES...THEY MAY ALSO OFFER SUGGESTIONS TO FIX YOUR PROBLEM---NEVER THE LESS--WRITE DOWN THE EXACT CODE NUMBERS AND POST THEM HERE (SOME CAN BE INTERPRETED IN DIFFERENT WAYS)

MY 2 CENTS, AT THE BOTTOM OF THIS POST MIGHT HELP TOO

I'M HOPING IT'S A BATTERY PROBLEM AND YOU BATTERY IS LESSER EXPENSIVE THAN MY WIFE'S NEW BATTERY

KEEP US POSTED

THE MEDIC

I would suspect a faulty ignition switch. Symptoms indicates interruption of power source and it is not adviseable to continue driving as the engine can stall anytime.

There was safety recall on this components and even if you have rreplaced the part, replacement can fail as well.
