What else should I do?

Was there an motor issue before this happened.

Roy

Check all the ground connections. They may be corroded or loose.

Roy

Grounds on the bell housing bolts on the trans and the grounds to the body. Start at the battery cables and work from there.

Roy

Did you remove and clean them?

Other than that, it is either the motor has an internal issue or you have a bad battery

Roy

HE'S RIGHT!......HAVE YOU DONE EXACTLY WHAT HE REQUESTED?????

BRAND SPANKING NEW STUFF CAN BE BAD TOO!

..........BUT

BEFORE YOU START SNATCHING STUFF BACK OFF

TIME FOR "TOUGH LOVE"...SEE MY LINK BELOW...I SEE THIS SAME THING EVERY DAY!

ANOTHER SURE SIGN OF THIS PROBLEM IS....FEEL THEM THERE BATTERY CABLES AFTER YOU CRANK ON IT A BIT....ARE THEY PRETTY DARN HOT?

RETURN WITH A BIG OLE GRIN!

THE MEDIC

AFTER THE NEW STUFF WAS ADDED DID IT DO ANYTHING?

. OR AFTER IT WAS ADDED IT DID NOT DO WHAT IT DID BEFORE?

"ROTATING SLOWLY". IN THE BEGINNING SOUNDED LIKE WHAT ASEMaster6371 AND I SET YOU SEARCHING FOR

NEUTRAL SAFETY WOULD NOT CAUSE SLOW ROTATIONS

THIS WOULD BE THE NEXT TEST YOU NEED TO DO----NOT KNOWING WHAT YOU HAVE DONE WHILE CHANGING THE STARTER. IF YOU DID NOT DISCONNECT YOUR BATTERY 1ST, YOU MAY HAVE BLOWN A FUSE OR FUSIBLE LINK. IF WE HAD SOME "SPARKAGE ISSUES" GOING ON

TESTS IN PICS BELOW---SEND BACK RESULTS. THIS WILL TELL US WHERE TO LEAN TOWARDS. GONNA NEED A VOLTMETER

2ND PIC--THIS IS A QUICK WAY TO TEST A FUSE OR FUSIBLE LINK THAT YOU MAY NOT BE ABLE TO SEE "IT'S INNARDS" TO TELL IF IT'S BURNT OR NOT

TAKE IT FROM HERE ASEMaster6371. ON TV THEY SAID, "SHARING IS FUN!"

THE MEDIC

WE ARE NOT GETTING "REAL" RESULTS ON THIS END

TEST ONE RESULTS.12 VOLTS. NO 12 VOLTS?

TEST TWO RESULTS.12 VOLTS. NO 12 VOLTS?

"BEEN THERE DONE THAT", OR ANY VARIATION, SORTA DOES NOT OFFER NUTHIN' FOR US TO DECYPHER

WE ARE NOT ATTEMPTING TO PIZZ YOU OFF. WE WANT TO HELP!

WE DO THIS IN OUR SPARE TIME

WE DON'T EVEN KNOW IF YOU HAVE A VOLTMETER

WE CANNOT PERFORM MAGIC FROM HERE

PRESENTLY 4, OF MY FLEET OF 5, ARE RUNNING. VERY WELL!

1) '77 CJ 5 "MR. JEEP" IS HOT TO TROT

2) '46 WILLYS---"WILLY" IS DOWN. NEEDS CLUTCH, TORN DOWN, PARTS ORDERED, I JUST FINISHED CLEANING ALL OF THE PARTS I PULLED OUT. WASHED MY HANDS, NOW IT'S TIME TO RELAX AND ANSWER 2 CAR QUESTIONS (I WILL HAVE PICS SOON)

3) '95 DODGE NEON "LIL RED"---INSTALLED HIS NEW BATTERY BEFORE I CLEANED WILLYS PARTS

4) '03 FORD ESCAPE--WIFEYS RIG. OF COURSE IT'S IN TIP TOP SHAPE

5) '76 FORD F-150--PRESENTLY SITTING AT MOM'S, HAS NOT BEEN DRIVEN IN 2 YEARS ON THE ROAD---ENGINE HAS LESS THAN 20,000 MILES. CRANKED EVERY 2 WEEKS AND DRIVEN AROUND THE YARD.I INHERITED IT WHEN MY DAD WENT TO SEE "THE GREAT SQUADRON COMMANDER IN THE SKY". GOTTA MAKE ROOM FOR FOR IT AT MY PLACE

HELP US HELP YOU!

WE NEED BETTER INFO

THE MEDIC

I would also like to add see if the engine turns over freely by hand.

Does it turn over freely by hand?

With a socket and breaker bar turn the bolt on the crank. Pulley clockwise.

So you have power to the purple wire with the key in the start position at the starter?
