Tell you what...I'll learn to read when you learn to spell...

It's cruise not cruse!

 

Oh and tire wall for you next kart day!

 

You can still use your highbeams, you flash them and the door openner sends it's signal, they still work after. All your really doing is using the switch to provide power to the other device.

 

Oh it's the engrish police agian

TIRE WALL TIRE WALL

 

Yes, I know, I know...I'll put you in it next time - sheeesh have some patience.....

 

I measured in multiple places. Including the Vout of the voltage regulator and the voltage drop across the garage door opener itself. IE I put the volt meter across where the +ve and -ve terminals would go on the lithium battery normally.

Both were seeing 3.2 volts or so. If I had an adjustable power source, I could vary the voltage across the circuit to see what the correct activation range was, but I don't have anything like that.

Any suggestions?

I'm working on a visio diagram of my circuit.

 

This is such a simple cct. Just dropping 12VDC down to 3.2VDC so you can use car power rather than a battery.

Try just powering the opener with the 12VDC through the cct and see if the button on the opener works.

 

You could replace R2 with an pot and that would give you and adjustable output.

If you measured the voltage at the points where it says + - to remote wire and got somewhere around the same voltage as when you have LI battery in, it should work...need a tech day to actually see this.

 

For like 20 bucks you can get a pre made adjustable voltage regulator and some wire to do this in 10min

 

Ummm...that is what the LM317 is!
