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!
Glad to help!
Nice presentation very positive and clear.
Excellent video and clear instructions!
Thank you, wish you would have shown how you "stretched the spring" to repair the sensor for our reference.
Yeah, I was in the middle of the repair and just got caught up in what I was doing.
Thanks for sharing, it was helpful
Glad it was helpful!
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.
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.
Take the wires off the sending unit and put them together if Gauge goes up, wires are fine.
It will be the sending unit
Pretty much yes
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
Thanks for providing the info
I did not know the ground to sender wire trick
Yeah, it should help a lot with the troubleshooting
I have opposite problem My all ways says full
You have a short somewhere between the 2 wires.
@@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
You have a lot of "firsts" in this video.
"Check this first." "First you do this." Etc. Etc. Etc.
Yeah, check all those first
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
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
@GearsandTech I took float out and there's about 3 inches in there
