IS THIS YOUR SENDING UNIT?

IF IT IS, YOU CAN TEST THE GAUGE OPERATION BY.......

TURNING ON THE KEY

REMOVE THE WIRE OFF OF THE SENDERTHEN TOUCH THE WIRE TO A GOOD GROUND

YOUR BUDDY INSIDE YOUR CAR SHOULD SEE THE NEEDLE RISE TO THE TOP---NO NEED TO KEEP IT GROUNDED, ONCE YOU WITNESS THE RISE

THIS WILL VERIFY THE GAUGE DOES WORK

IF THE GAUGE SHOWS GOOD, IT'S MOST LIKELY A BAD SENDERI'VE EXPERIENCED THIS WITH MY '77 JEEP CJ 5, AFTER 4 NEW SENDERS FROM 2 FROM ONE STORE AND 2 FROM ANOTHER, I THOUGHT, "SURELY, ONE OF 'EM WAS GOOD?"

THEY WERE INEXPENSIVE FOR MINE--LESS THAN $10 EACH, MAYBE LESS THAN $5

THIS WAS OVER A SEVERAL MONTH SPAN OF TIME---I HAVE A "2ND" TEMPERATURE GAUGE, IT'S MECHANICAL AND WORKS FINE (IT HAS ACTUAL NUMBERS--NOT JUST "H" AND "C" LIKE THE ORIGINAL)

SO IT WAS NOT "CRITICAL" TO GET THE ORIGINAL TEMPERATURE GAUGE IN MY SPEEDOMETER CLUSTER WORKING---I JUST THOUGHT IT WOULD BE NICE TO HAVE EVERYTHING WORK!

I PICKED UP THE 5TH TEMPERATURE SENDER AT NAPA AUTO PARTS---WORKS LIKE A CHARM!

I RECKON IT'S THE MANUFACTURER THAT MIGHT MAKE THE DIFFERENCE SOMETIMES
