This def saved me a trip to the shop. I literally opened the sensor stretched the gauge and put it back on. Voila, it’s working again. Thank you sir!

[@GearsAndTech]

Glad to help!

[@niratocco4709]

Where is the spring located, please? thanks in advance.

[@kenjohnson2194]

Nice presentation very positive and clear.

[@garylcarrier]

Excellent video and clear instructions!

[@vincedeluca226]

Thank you, wish you would have shown how you "stretched the spring" to repair the sensor for our reference.

[@GearsAndTech]

Yeah, I was in the middle of the repair and just got caught up in what I was doing.

[@niratocco4709]

@@GearsAndTech So we still don't know how to stretch the spring or where the spring is located. :( Other than that, interesting vid. thanks.)

Take the wires off the sending unit and put them together if Gauge goes up, wires are fine. It will be the sending unit

[@GearsAndTech]

Pretty much yes

[@rickl6697]

I've never had an ohm meter that had an internal resistance of 85 ohms. Mine are typically around .6 ohms. .6 ohms🤪. Maybe your sending unit has a pull up resister installed of 84 ohms. Touch your meter's probed together and that will tell you the internal resistance of your meter. Maybe you need a new meter or a new battery for your meter. After watching it again I think you meant the gauge in the dash has an internal resistance of 86 ohms not the ohm meter. To measure the fuel sender resistance it's best to at least remove one of the wires(or both) before measuring.

[@AdventuresofHappyOurs]

The vast number of problems I found with fuel gauges is poor connections. Given the 33-190 ohm range of most senders, this makes it difficult to trace as a high resistance connection will read a higher resistance than normal, possibly indicating a false empty or even half tank when it is actually full. Shorting your sender wire may even still give you a full reading as the gauge only needs 33 ohms for full. You need to determine if the high resistance is on the sender wire or the sender ground at the tank. Using a long jumper wire from the gauge helps to determine which it is. Then tracing the offending wire from each connection point to find the bad connection or just run a new wire as it’s sometimes easier than tracing every connector and splice. A high resistance open can be invisible to the eye and can even be in the middle of the wire hidden in the boat somewhere.

[@GearsAndTech]

for sure there are a few ways to diagnose and test an issue. What I show is one way, but is not the only way.

Great trouble shooting video!! Thank you😊

[@GearsAndTech]

Hope it helped

[@johnengland8619]

Thanks for sharing, it was helpful

[@GearsAndTech]

Glad it was helpful!

[@frankdavidson9675]

when ordering a reed swith sender measure the depth of tank mins 1/2 inch the read 33ohms full 240 ohms empty you test before installing set meter on low ohms conn meter to the push on conn on top of sender move float up and meter should read 240 empty 33 full gasket coms with it install it run 2 leads to gauge on dash = and - conn batt from switch to batt on gauge

[@GearsAndTech]

Thanks for providing the info

[@HRIINSURANCE]

I did not know the ground to sender wire trick

[@GearsAndTech]

Yeah, it should help a lot with the troubleshooting

[@toddbollen1455]

I have opposite problem My all ways says full

[@GearsAndTech]

You have a short somewhere between the 2 wires.

[@toddbollen1455]

@@GearsAndTech I was thinking float maybe stuck ? But never really worked right since bought boat .I bought new. It would say full than all Sunden drop down. less than half Now always says full. I pull float out this week end look at it..Take from there..Not afraid to try after watching your video

[@BA-gn3qb]

You have a lot of "firsts" in this video. "Check this first." "First you do this." Etc. Etc. Etc.

[@GearsAndTech]

Yeah, check all those first

[@markmorgan5031]

Hi..I took my gauge out of the tank...the float works by moving it by hand ..but when I put it in the tank it doesn't read on fuel gauge and when I put it back in the tank ..looks like the float doesn't raise up.any comments

[@GearsAndTech]

That's really weird Are you able to rotate it 90 degrees in the tank? Possibly it was installed wrong and is hitting the edge of the tank the way it is. Only other option is you're out of gas

[@markmorgan5031]

@GearsandTech I took float out and there's about 3 inches in there

[@niratocco4709]

If u have the arm with float-on-the-end style, it might be that the sender unit was reinstalled in a position where the float will hit the side of the tank.
