I have this 1988 K75S and now i'm turning it to a cafe racer. I removed the instrumental cluster because it's so bulky. I'm using sigma speedo but fuel level warning light would be nice. I'm thinking about a simple led ligt. Would it work?
-
I've designed and had circuit cards made for a single LED fuel level indicator for the K-bike. It will display Green with a full tank, flash green with 50% full, Red at 25% full and flash red with 15% full. It works with the later fuel level senders only. The circuit plugs into the 4-pin connector on the K-bike harness, under the tank.

Today I change the oil (first time since I've owned it) and changed the final drive oil (certainly for the first time).
Oops, wrong thread. Is it possible to delete a comment?
-
RBM, by later what years are you talking?
-
'85 and on K100. All years of K75. It's the sender that is a variable resistor-type driven by a float arm.

Do you mean that connector?

Rbm,
Do you have plans for this circuit? I'd love to build something Like that.

Me too :yes

Yes, that connector

Yes, I have plans and boards. I can sell the raw boards or completed units; picture of the unpopulated card below:

I've designed the unit under the Open Source Hardware copyright so the design is in the public domain. It uses a Digispark to read the sender and drive the LED so you'll need to have a computer to program the Arduino with the code I've written.

Thank you very much! This will be awesome!

hi robert,
still have completed units available? what does it include? price?
Thanks!
-
I've boards and parts, no completed units. Actually, I should complete at least one unit to test that it functions just like the prototype, but I haven't followed up on that intention. The fuel indicator hasn't been popular. If you're interested, I'll dedicate the time to getting one working for you. I haven't determined a price just yet because I have to determine my costs; it's going to be around the $20- $25 mark I suspect.
-
would love to try one Robert. sign me up! getting tired of staring in the fuel filler hole or guessing from the miles. a simple LED setup in the dash is cleaner than cutting a hole in the fairing for an analogue gauge.
thanks!

I'm interested.
