low fuel sending unit connector

[philwarner]

I ordered a low fuel sending unit for my 1996 California and when I went out to see if it would work I found that the 2 male pin connector on the unit is the same as the 2 male pin connector under the tank that I assumed was for the sending unit.  I haven't pulled the tank yet, but could this connector be for something else?  Or did MG Cycle send the wrong unit for my bike?

This may not be of much help....
The circuit I maybe to do a light test, and stop the flashing light, implies that the motorcycle side had a black wire, and a yellow/white wire.

The schematic that I have agrees with that. So you need a plug on the motorcycle side that has a yellow/white, and a black wire.

I may have an old sensor that I can look at. I'll look for it. (I save way to much old crap like that)

Like I said, I keep too much of that crap.

That sensor in the top picture is a magnetic reed switch (float switch), the reed switch inside the tube is triggered by a small magnet in the float

The bottom picture shows what looks like a similar sensor

Before you commission your new sensor find the female in the loom and short the two contacts with a short wire to test the light, if it doesn't go don't plug th sensor in.
Reed switches are typically rated for less than 1 Amp, too much current will weld the contacts together/
You can test the float switch using a multimeter on Ohms.

False alarm.  I pulled the tank and found the female low fuel connector tucked up among the wires and the sender and warning light work fine.  I think the other male connector might be for the kickstand switch which is non-functional as in disconnected.  Not sure I need to re-connect it because I once drained my Triumph's battery when when the stand switch killed the engine and I forgot to turn off the ignition because I didn't notice the "dash lights" in the bright daylight; its ignition switch is down on the left side behind your leg so it is not as noticeable as the Guzzi's, but I still might forget under the same circumstances

    Now I have another problem.  The right side tank rubber donut which came out with the tank and the left one with a bolt through it looks a bit bodged.  There is just a square hole in the frame where the right donut should be so I assume there was a captive nut of some kind that should be there, and the left side donut bolt just turns and does not loosen or come out.

Look at your rear tank hold down, many had the same captive nut(junk).  It's most likely laying on motor or between fins.

I'll definitely look for it because I thought I heard something snap when the right side of the tank came loose before the left side.  However, this bike has apparently had a lot of different hands on it before I got it and the right side rubber donut the came off with the tank does not look like the left side one and it may be that neither of them is stock.

This bike also has a hydraulic clutch setup that I am sure was not stock and it has a brake light that blinks 4 times before it goes solid which is a nice safety feature.  I keep finding new things - some good some bad - but always interesting.

Hydraulic clutch was not stock - it would have been cable operated.

Someone really hacked up that poor thing.

Is it the original tank?
That is NOT the original rubber tank bumpers. The original is a bolt that hold a metal plate. The metal plate then has a rubber cover pressed over it.

Yea, looking at the pictures, I'm thinking that is not the original tank.
