Electronics help needed.

[Stealthblade]

The PO of my bike put a button on the ignition cowling. Nobody at the dealership bothered to ask him it's purpose.

 

I took off the right lower fairing a few weeks ago and came across a zip-lock baggie with a couple circuit boards taped to the fairing.

 

Well, today I thought I would try to figure out what was up.

 

... came up with nothing and thought maybe an electronics guru or 3 could offer suggestions.

 

There are 4 wires coming from these two boards. The two blue ones go to the button on the ignition cowl and the red and green are hanging loose under the seat ( for connection to battery power )

 

I don't know how to attach bigger pictures, but I have typed in every string of numbers to google and have come up with nothing.

 

Any help or thoughts would be appreciated.

Never seen anything like it.

Its a garage door opener the chip on the prefbord reduces the voltage to a level uadable for the opener youcan tell where they soldered rhe leads to the batyery contacts

The second one looks like a voltage regulator supplying the other board.

Can you post a close-up of the IC chip or see a number on there?

The S1 S2 and S3 you see are for the opener switches and the crystal on the borad is for the transmitter section.

Thanks :}

Yup, Garage door opener and a regulated power supply.

 

Just pull it out and toss it, odds are it will not work with your door.

But if you can figure out what kind of remote it is you might be able to reprogram it for your door.

Just ride down the street pushing the button. See what comes up.

See if your opener has a learn switch and use it on your own

[syscrusher]

Even if it doesn't work on your door you could buy the keychain remote for your door and wire it in instead of the larger of the two boards. The red and green leads that are attached to it are supplying coin battery level power for the board and the blue leads are coming from your dash mounted switch and are making one of the connections for the pushbutton switches on the remote. Just insert your own remote and you're good to go.

 

I do think that I recognize the remote though and it is for the previous generation of Chamberlain/LiftMaster/Craftsman garage door openers and the remote will work with (nearly) anything from those distributors except for the very most recent door openers, or maybe really old ones that are before the rolling codes technology.

It's a 970 or 956.

Was replaced by the 890 MAX, which works with the most recent openers too.

 

Definitely try programming it in for use with your door if you have a lift from any of those companies.

Yup, Joe is right on. The first board has a voltage regulator to reduce the voltage to the opener voltage. The other board is the opener but needs some kind of push button to activate it. Chuck the green board, the perf board could be used to power a new remote...

3rd or 4th the garage door opener

Yep, excellent pun
