Gear display

[Otyesz]

Can you build GL 1500 SE motorcycle gear indicator?

[WingAdmin]

Yes. I built one for mine:

Yes. I built one for mine:

Wow.
I'm guessing that's not in the Electronics for Dummies handbook ?
Just how difficult was that to build ?
And, does it fit right in the dash where the OEM LCD display was ?

[Charlie1Horse]

Check ebay. I have seen them on there. They fit right in where the OEM indicator would be. Thinking about getting one for my 92 Interstate. But, doesn't your SE already have one??

Those who say it cannot e done should try not to interrupt those who are doing it.

Here is what I have done and shared in the following link.

No, it wasn't a simple thing. I built it more for fun than anything else - I designed the circuit, and tested it on a breadboard. I then wrote the software that runs it (about 1500 lines of code) which for me was the most fun.

In my design no code is used, anyone who can solder some parts can built this, and the cost will be very low like 10-20$.

It has two parts, indicator unit and the control unit, which creates the first gear signal using a logic circuit in it.

Here is a daytime picture of the product.

To be fair, my device does much more than just tell you what gear you're in.

I had watched a video on YouTube, I think it was yours.

And here are two videos from a German guy.

Thanks for your help. I found on Ebay cheap solution, but the German guy lennne development on the best solution.

I can solder, etc .... but I just bought mine in 2004 on sale at a rally, Air Rider sold it. Gear & Volts, dims at night too.

Wingadmin,

Any other info on the one you built? Still have the plans and code so that others may follow? Or heck, want to sell me one?

Interesting - I notice that he is using the same LCD panel module as I used. it looks like he is designing his as a replacement for the original GL1500 LCD panel, with the aim of perhaps selling them at one point:

I do, but I've had plans to rework it and make some changes. I designed it as a one-off, it would need quite a bit of work to make it into a saleable kit, unfortunately.

The cheap solution you found will not show the first gear, I guess. Because GL1500 does not have a first gear signal, on some earlier models (I couldnt remember the years now) even the second gear signal either, you will need a gear indicator which is specially designed for GL1500.

Or you will need the control unit that I have built to connect the indicator you found.

You can do it without the first gear switch, using logic. There are positions on the switch for Neutral, 2nd, 3rd, 4th and 5th (OD). Therefore, you can safely assume that if none of those contacts are closed, that the transmission is in first.

Yes of course, but this would not be a technical solution.
Here is the technical solution.

Enderniz:
Excuse me for chiming in, but following your posts I've ready spliced wires and have the 6 wires hanging behind the right pocket, waiting to fix up the display.
Going up a little more I would like to use a BCD and a seven segment display, but I don't know if this is possible because the signal from speed selector is a 0V (ground) and the BCD requieres an imput of +5V to work, do you think is it doable??. I'll appreciate your comments about it.

Gipsy,

Here is a $3 gear indicator, in various colors on Aliexpress. It needs ground inputs for gears.

You can use black/white wire for +12v in the C57 (9Red) connector, and get N,2,3,4,5 gear inputs (all of them are grounds) from the C59 (6Blk) connector.

If you like to have a 1st gear input, you will need the control unit that I have built and shared the details.

I don't know if I could answer your question.

You are using logic in your solution - only the logic is encoded in hardware, using diodes and a transistor, rather than in a processor executing code.

I'm curious, what is the purpose of LA through LD? They appear to be on at all times?

Gipsy,

I don't know if I could answer your question.

Hi Enderniz
First I appreciate your input and time to search, but Sorry you didn't get to my question. I'm not interested in that commercial unit, It probably will cost me more this way, it isn't for the money, it's more a personal joy.
As stated before I decided to build your circuit, and since I've had the tuperware out (carbs problems) already have the wires taken from C59 connector.
Just thinking to make some change and upgrade to a seven segment display, my problem is the one I pointed to you, how to swap a -(0) signal to a +(1) signal, (my poor electronic knowledge) . may you help me?? Thank you in advance .

[Erdeniz Umman]

I had explained it in the related link, but let me add some more details.
Yes it is absolutely a logic circuit.
The LEDs A-D are just for illumination of the writings and the ring around the case, and they are blue.
I did not want to use a digital 7 segment display, because I didn't like its appearance on the bike. I wanted some extra lights which look beautiful in dark.

Gipsy,
Actually I had gotten your point, and wanted to draw you into that solution. But if you want such a circuit, first you should design a coder circuit to convert gear signals into binary inputs, then decode them using another bcd circuit. Since I didn't know your level of expertise on electronics, I thought it would be easier for you.

And, to give a basic answer, you can change any negative signal to a positive signal by using a pnp transistor; and any positive signal to a negative signal by using a npn transistor. Of course, you should limit the current using proper resistors, and some capacitors, according to your circuit design and component specs you will chose.

Thank you a lot for your explanation, I'll keep going ffrom here.

I have seen another circuit design that uses a maze of diodes and transistors that encodes the five gear switch wires into 7 outputs to drive a 7 segment LED - no intermediate binary or BCD driver. It literally lights up the segments for the digit "2" for instance when the 2 switch is engaged, purely through a bunch of diodes and a few transistors. Complex and not very efficient, but it worked.
