Fixed fuel sending unit, but its to sensitive

[Triorieel]

I bypassed the internal fuse and installed one on the wires (easier to replace later).

I cleaned fuel out of the float, and tested each internal reed switch.

I installed fuel sending unit. Filled tank. Took seadoo out on water, did a little drive and some circles and back and I could see the gas gauge working one bar at a time but going down fast.

By this point the seadoo is claiming fully empty (and beeping *1). I looked at the fuel tank and it's barely under the seem (45%). As I am putting fuel in, the gauge increases 1 bar at a time (telling me the individual reed switches are still working and the mpem is reading it correctly).

Did they make a shorter sending unit (maybe for another unit) that a previous owner/mechanic installed?




*1) I don't know why they long beep every minute on low fuel. I hate the engineer that decided that. Info Gauge says fuel low, you have a fuel gauge, the red light blinks AND you have a reserve option. The 99 and 2000 don't beep....I guess its a 98 ltd thing. I would have been okay with it if it was just a single beep, but to hear it keep going off on the way back to the dock through the channel is irritating.

my guess is the float filled back up and started sinking again.

I've never liked 'fixing' these. It's an electrical device surrounded by an explosive liquid on a small craft. $180 is a lot less than replacing a leg...

It registers a full tank.

It's the way they work. The boards contacts are exposed to the fuel (they aren't coated with anything). Soldering a bypass wire won't make it any less safe. You could argue the opposite since I am taking the fuse out of the tank.

Like spim, I think your float sunk

I will take another look, but I did just drill it out and seal it.

Just buy a new float. They are like $10.

Well, tired of going 5 km's and having it beep, I decided to put the sending unit on the back burner until the rpm flat spots are fixed...and no way am I going to have that beeper go off in my ear while I am figuring things out....so I jumper-ed the sensor.

The weird thing is...once jumper-ed it was only showing 7 of 8 bars. That is, until I started wiggling all the wires. I now think the problem is a bad connection, but I am now going to ignore this until the engine side of things is fixed.
