Hmm, maybe if you got the little components and laid them out the visual would click something. When I was a kid my step dad bought me a metal detector kit, as in he had me solder all the little diodes and capacitors to the board and assemble it. I have a simple understanding of parts, like 90gt, parts and how to use them but have no idea how they work, that makes my eyes glaze over sad to say.

The Higher the resistance the faster it draws off the capacitors. Stepthrutuner was correct on the delay on starting it up so what I did was to add a SPST switch in the circuit. The switch will need to be turned on so that it bypasses the SCR when you start the scooter. The 5 second delay on start up and shut down does not make difference when I start my car because 5 seconds without music is not a big event but if in a hurry to get somewhere on a scoot this would become aggravating.  |

I had a brain storm and came up with a much better idea than buying parts and putting them together.
Go to your local junk yard and find a car that has a dome light that has the delay. The circuit for the delay is in the dome light and this could be used on your scooter for the delay shut off.

One more thing that you could do if you just dont want to remove the key is to put a switch in between the ignition switch and the the + wire going to it and mount it on the dash or close to the handle. You could even use a switch like this one www.radioshack.com/product/index.jsp?productId=2062535#It has 8 switches built into one piece and you could hook it up so that you would have to switch certain ones, like a combination lock in order for the scoot to start. So you are adding anti-theft at the same time. I know the picture of the switch doesnt show it but the switches are labeled from 1 to 8 and on and off. |

Here is a better picture of the switch.  |

The Higher the resistance the faster it draws off the capacitors. I think you are thinking in terms of current or something but a higher valued resistor slows the charge/discharge rate of a capacitor. Less current flows through increasing resistance. |

Correct you are, a 22k resistor will drain faster than a 100k resistor.
You could always put a variable resistor in that way you could adjust the time delay to what you want.

Just for the benefit of anyone who might want to build this circuit. The timing resistor is R1. The lower 100k/1mF r/c set is for gate stability under varying output load.
Did I mention I once owned a water cooled slide rule back in the day. ;D

Thats pretty good, I am glad there is some one else out there that I can share my ideas with and get some advice.
Glad to hear you are knowledgeable in electronics. :thumb:

Here is a better picture of the switch. That thing come with switches to flip the switches :stumped: . lol, ide play hell flipping those lil things :disco: |

LOL, it would be nice but hate to say it but no.
I used to have one on a motorcycle and would use my key to flip the little switches.
