i bought a new one and checked with multimeter and empty side reads 73.6 and full side reads 8.2 consistently,should the full side read 10.2? thanks

2 ohms difference won't be an issue. If it read 100 then you'd be in trouble.

How good is your VOM meter? Will it zero on ohms? If not add your zero error into the readings
I thought all Mopar had 30 to 90 ohm fuel sending units
I'll dig out one of my FSM and read that part over again on trouble shooting the fuel gauge circuit.

Most Volt/Ohm meters have a 5% tolerance for its respective readings...


Just my $0.02...

when i installed my new one i had 75 and 13. i was and still is 1/4 of a tank off no matter how much f'ing around i did.

as Supercuda stated, 2 ohms makes no difference...

FYI- i got mine from Dixie Restoration and it's made in Mexico. we all had high hopes for these ones.

My experience is 8-10 ohms full, 80 ohms empty on original equipment. Very non linear as well due to the shape of the tank.

how do you know if a ohm meter is bad.mine never seems to settle in to a fixed ohm.is there a fix for that or a good test,its didgital.my new gage is WAY off but my meter is acting weird so i cant even test it.

What brand of meter? Fluke meters have a range button. If you take it out of auto range you can change the values to get rid of the 'bounce'

that could be the prob it doesnt have a range setting,just a ohm symbol.i put my old unit back in and it reads perfect on the gas gauge but i need the 1/2 inch unit for my combo.

I went thru 3 bad sending units. They are junk. I bought one from Kramers auto and it reads perfect.

Digital VOM can drive me bonkers even after using Triplett analog VOM for years. I still have and use several of the older Triplet VOM that I use as well as several different Radio Shack brand small hand held cheaper digital VOM and one good Fluke 80 digital VOM.I still need to read and under stand the instruction for this meter
If your going to test low ohm resistors in appliances and audio amplifiers use the best meter you can get If your testing for general automotive use most of the other VOM will work fine for that application

At be just me but I've found that you YOU cannot be touching the probes or wiring when checking this stuff. The better meters will actually read the resistance of your body! And yes the human body does have resistance and the ability to conduct electricity.

Few years back I was feeling some stray voltage in the wiring to one of my lifts. Couldn't measure it on a meter but it was there. Took a few days to figure out it only happened when I was touching the lift and the compressor was running found a wire in the compressor just barely touching ground.

One of the first test we had to do in basic direct current electricity class in college was to zero the VOM meter and measure our bodies resistance, I learned early the harder I pinch the probes the less resistance my body had I think they where teaching back then that our bodies are 80% liquid, women have less body resistance than men also
I'm trying to remember which Rock and Roll singer died when the cord to his microphone got worn and shorted out inside, he touch the mike to his lips and died from being electrocuted on the stage

clue CB, you don't zero DMM and only a seriously old fart still has a VOM.

Went to their web site all they had was sheet metal

Lay off of Cab, your ignorance is showing. A digital Multimeter IS a VOM. See quote below:

"A multimeter or a multitester, also known as a VOM (Volt-Ohm meter or Volt-Ohm-milliammeter), is an electronic measuring instrument that combines several measurement functions in one unit."

Straight from the internet bible of knowledge, Wikipedia.

There are some things where the analog indicator is better than digits. That's why Fluke, several years ago, added a bar graph that works in analog fashion.

As for me, I have a Fluke, the cheap Radio Shack pocket meter, the Freebee from Harbor Freight, and two GBs purchased from Walmart. Oh, and on my bench I have a pristine Simpson 260.

You can never have too many tools.

R.

it's in the catalog. $125 for 1/2 or 3/8 if i remember.

You need to call them and ask.

Same source, your internet bible called Wikipedia says "Digital multimeters (DMM, DVOM) have a numeric display, and may also show a graphical bar representing the measured value.

VOM is analog, DVOM or DMM is digital.

Reading comprehension is key.

As for the Simpson 260, they were crap new, I used to have to repair and calibrate them and they were a giant bakelite encased POS. Thank god for Fluke and the DMM.

Most of the larger Simpson meters our cable splicers and C.O. techs. used where good stuff, they lasted a long time I'm not sure of the model number now twenty yrs later
I bought several of the cheaper radio Shack DVOM to use as a trial in one of my work groups, the constantly changing ohm reading drove some of my outside plant techs. crazy when looking for grounds and shorts so I took them back later and made them go back to using their little analog Triplett meters, end of problems
