2000 Pontiac Bonneville electrical maybe?

UN-JEWG YOUR BATTERY

INSTALL FULLY CHARGED OR NEW BATTERY...IT DON'T MATTER.
.
.

INSURE CHARGING SYSTEM WORKS....A POPULAR AUTO PARTS STORE WILL DO IT FOR FREE MOST OF THE TIME
.
.

YOUR "POSSIBLE" "RUN DOWN" BATTERY MADE THE COMPUTER GO HAYWIRE......LIGHT ON, DOOR OPEN.....MAYBE A PARASITIC DRAW

MAYBE "JUMPING" YOUR RIG, FIRED YOU UP, .......MADE IT GO..............

...................BUT IT WAS NOT "THE FIX" !!!
.
.

BUT.......MR. COMPUTER IS STILL HAYWIRE, FROM THE VOLTAGE DROP INITIALLY..........IT IS STILL RECOGNIZING LOW VOLTAGE!

UN-JEWG-ING MR. BATTERY COMPLETELY AND MAYBE ......A.......10 MINUTE WAIT, SHOULD RESET MR. COMPUTER................BUT WAIT!!!....THIS'LL ONLY FLY, IF THE BATTERY IS GOOD, FULLY RECHARGED OR NEW

............LET'S GET THE BATTERY TESTED AT A POPULAR AUTO PARTS STORE!......THIS IS USUALLY A FREE SERVICE!

THEN INSTALL A "FULLY CHARGED" BATTERY (YOUR OLD ONE MAY BE OK--CHARGE IT)........CHARGE THE OLD BATTERY 1OO% OR IF IT'S BAD INSTALL A NEW ONE
.
.
BEFORE YOU HOOK IT BACK UP IN THE VEHICLE!

THEN IMMEDIATELY OFF TO THE PARTS STORE---FOR MORE TESTING!

........THIS TIME, HAVE THE ALTERNATOR TESTED....WHILE IT'S STILL IN THE VEHICLE!...AND THE VEHICLE WILL STILL RUN

THIS IS A TEST YOU CAN DO AT HOME, TO SEE IF THE ALTERNATOR'S CHARGE REACHES THE BATTERY.........THIS MAY BE A BAD ALTERNATOR OR JUST A PROBLEM IN THE CIRCUIT (FUSE, FUSIBLE LINK, BAD CONNECTION)...........HOWEVER, THIS IS NOT A LOAD TEST, LIKE AT THE AUTO PARTS STORE

BAD CONNECTIONS...EVEN AT THE BATTERY MAY BE THE PROBLEM

WE ALSO NEED TO REMEMBER........A BATTERY, AN ALTERNATOR, OR "ANY" AUTO PART CAN BE BAD........RIGHT FROM THE "GIT-GO!"......OR CAN "GO BAD" AT IN ANY LENGTH OF TIME!

LET ME KNOW WHAT YOU FIND

THIS MAY HELP IF YOU NEED A NEW BATTERY OR ALTERNATOR....YOU CAN BUY WHAT YOU NEED, OUT THERE, IN THE PARKING LOT, ON YOUR SUPER CYBER PHONE......THIS DOES NOT WORK FOR OILS OR ITEMS ON SALE
