89 Electra Glide Fuel Sending Unit
Hey guys,
Searched the forum trying to find an answer to my dilemma and couldn't find what I was looking for.
Here's the issue: Fuel gauge doesn't work. OK, so I checked the fuel sending unit (followed instructions in the service manual) and concluded that the unit is bad. Called my local HD dealer and they said that the part is no longer available through HD.
Can someone please help me out with a place that sells either the stock sending unit, or an aftermarket replacement? I searched the internet and found no results for a place to order this part from.
Thanks everyone for the help in advance.

My gauge didn't work on my '88 when I got it. I pulled the sensor out and put a meter on it and fiddled with it. It's just a variable resistor. The contact wasn't connecting well. I got it to work, it's not perfect, close to a 1/4 tank off, so it shows empty when I still have a gallon of gas. That's ok with me. Before then I just counted miles. I have no idea where you would find a new one.

Ditto bluharley ... have done the same with many automotive fuel sending units.
If yours is the variable resistor type with a coiled wire resistor and a wiper contact , try cleaning it with carb. cleaner then visually inspect it for damage or check it with a multimeter. Usually the wiper contact is worn or weak and needs to be bent a little to provide a good contact as it travels across the resistor wires.

That's it machinehed, exactly what it is and how I fixed it, couldn't have said it any better! If I wanted to mess with the float level, I could probably get it more accurate, but it's close enough for me.

Bluharley and Machinehed: I will give that a try tonight with the carb cleaner. Didn't think of that... I wasn't getting any kind of reading off the multimeter when I checked it, hopefully after your trick I can alteast get the needle to move!
IronWright: Harley never even gave me a part number when I called them. I will definitely take down that P/N though... any idea if another type of sending unit would fit? like maybe off another model?
Thanks again guys, the help is always great here

Of course the one we need is the most expensive on the list! For $153+, I'll settle for a 25% error and/or count the miles! That's a good resource though, thanks Iron! Hope you get some kind of reading Cody, let us know what happens. You could always scour the salvage yards for a used one if your is really shot.

No reading at all ?
Check the wiring connectors at the sender.
Ensure the wiper is in good contact with the resistor as it moves through.
Meter the resistor for a open circuit , if you read no continuity get a magnifying glass and
find the open spot and mark it for identification then come back and i will get into how to
do this nasty little repair.

Alright guys,
Got some great news. First I want to thank all of you again for all the help; appreciate it alot!
So i took what you had said machinehed, I cleaned the unit off with carb cleaner and got alot of the heavy stuff off. Next I took a can of Contact Cleaner (bought at Radioshack) and sprayed the wiper contact area as well as the connection at the bottomside of the tank mount. It immediatly started sizzling and popping (cleaning all the extra bad stuff off). Cleaned it off another time with carb cleaner than with brake parts cleaner (to remove any residual oils from the carb cleaner) and i got continuity!!!
This fixed worked VERY well, but not until after I sprayed the unit with the Contact Cleaner. Think that may have really taken off the crap from the gasoline from the wiper contact.
Thanks again! Glad to report back some successful news!
