FORD F-250 ALTERNATOR PROBLEM

1990 Ford F-250

My husband changed the solenoid on the truck because it wasnt starting by the key. Come to find out the rod in the column had came loose. So now he put the original solenoid back on and now the battery light is on. When we take the terminal off the motor dies. Which means the alternator is bad. But we had it checked and its showing good. We used test light to check the wires, and everything is showing fire on them. So any ideas please. Thnx so much.
** I used ur website to put my 99 oldsmobile intrigue (3.5 engine) in time. It was a great idea for me to come back to you all with this problem.

WE NEED TO REMEMBER.....I'VE HAD NEW STUFF BE BAD, RIGHT OFF THE SHELF, JUST 'CAUSE IT WAS NEW AND WORKING YESTERDAY DOES NOT MEAN IT'S THAT WAY TODAY

THIS PROCEDURE CAN DAMAGE AN ALTERNATOR TOO

MAYBE 1985 ON BACK---SNATCHING THE BATTERY CABLE LOOSE WHILE IT WAS A RUNNIN' WAS NO BIG DEAL

FROM THEN TILL NOW----YOU ARE LOOKING FOR TROUBLE BY CAUSING A "SPIKE" INTO THE ELECTRICAL SYSTEM.......MIGHT EVEN GET TO BUY YOURSELF A NEW CAR COMPUTER OR AN ALTERNATOR........WHAT A DEAL!....NEW STUFF FOR THE TRUCK.....FROM A SIMPLE 1960s TEST!

.............BAD BOY!........BAD GIRL FOR "AGGING HIM ON"!

NOW-A-DAYS, "SENSITIVE", SEEMS TO BE THE ANSWER TO EVERYTHING, FROM YOUR CAR TO CREATING A "POLITICALLY CORRECT SOLDIER"

I DON'T KNOW HOW YOU TESTED THE ALTERNATOR.....THE BEST WAY IS ON THE VEHICLE, AND LET A POPULAR AUTO PARTS STORE "LOAD TEST" IT FOR FREE

WE WANNA MAKE SURE THE ALTERNATOR JUICE IS MAKING IT BACK TO THE BATTERY.....THIS SIMPLE TEST CAN TELL YOU THAT...SEE MY LINK

EVEN THOUGH YOU ARE TESTING WIRES---ALSO GOTTA MAKE SURE THE CONNECTIONS ALLOW THE JUICE TO MAKE IT ON THRU....THIS LINK IS SORTA MY "DRILL SERGEANT" APPROACH OVER THE NET...IN TEXT

I TOO USE THE OLDER FORD TYPE SOLENOID IN BOTH OF MY JEEPS -- THE ONE BEFORE YOURS --IT'S NOT UNCOMMON FOR THE RINGS STACKED UP AGAINST THE POSITIVE BATTERY CABLE ON THE SOLENOID TO GET DIRTY/ LOOSE/ MINOR CORROSION WHICH WILL NOT ALLOW POWER TRANSFER FROM ONE TO THE OTHER

CHECK YOUR FUSIBLE LINKS ALSO----SOMETIMES THEY ARE IN THE FUSE BOX, ON OLDER FORDS AND JEEPS THEY ARE AT THE SOLENOID

THEY ARE THE BEGINNING PIECE OF WIRE (A FEW INCHES LONG) WHEN THEY FRY IT'S EITHER "OBVIOUS" THEY ARE BURNED THE WIRE IS GONE/ SHOT, THE INSULATION STRETCHES OUT LIKE A RUBBER BAND---VOLTAGE TEST/ TEST LIGHT WILL CONFIRM NOTHING IS GETTING THRU THAT SECTION

I MAY BE ABLE TO GET YOU A "MITCHELL I" WIRING DIAGRAM FOR THE CHARGING SYSTEM...I NEED THE EXACT NOMENCLATURE FOR THE TRUCK AND THE ENGINE SIZE.......THIS WOULD SHOW EVERYTHING, WIRE COLORS AND LOCATIONS OR NUMBERS OF STUFF....LIKE THE FUSES INVOLVED

LET ME KNOW WHAT'S GOING ON---IF YOU NEED MORE ASSISTANCE---I'M NOTIFIED VIA EMAIL WHEN THIS POST HAS ACTIVITY

A CHEAP DIGITAL VOLTMETER IS ALMOST A MUST......USEFUL LATER TOO!

YOUR TURN

IN THIS PIC OF "WILLY"......MY 1946 WILLYS JEEP

"3" AND "4" ARE FUSIBLE LINKS.......ONE HAS A TAG ON IT, THE OTHER DOES NOT

THEY ARE ABOUT THREE INCHES LONG AND ARE SIMPLY TIED INTO THE WIRE THAT "WOULDA" HOOKED ONTO THE SOLENOID

IN THIS CASE ONE OF THESE GOES TO MY ALTERNATOR.......THE OTHER RUNS MY ENTIRE FUSE BOX

...............I KNOW THIS BECAUSE I BUILT "WILLY" FROM WHAT WAS LEFT OF HIM OUT IN A FIELD......I DID EVERYTHING TO INCLUDE 100% OF THE WIRING. I PRETTY MUCH USED A 1979 JEEP (AND WIRE DIAGRAM) AS A GUIDE TO WIRE HIM UP MORE MODERN.......ORIGINALLY HE DID NOT HAVE FUSES

THESE "FUSIBLE LINKS" ARE THE LAST LINE OF DEFENSE BEFORE THIS MIGHT HAPPEN........

I GOT SICK.....THREW UP.....HAD TO GO LAY DOWN AFTER SEEING THIS VIDEO..........MAYBE I'LL FEEL BETTER BY THE TIME YOU RESPOND

THIS TOO, ANOTHER REASON FOR ME NEVER TO USE A STEALERSHIP!......DIY....ALL THE WAY!
