I have gone through at least 4 batteries over the years due to leaving the key on for days after parking my scoot in the garage. I almost did it again today and the idea came to me that maybe there's a way to install a circuit that will cut the power after 5 minutes if you leave the key on with the engine stopped. Kinda like what turns off the headlights on a car after you park it.
Anyone know how to do it?
Thanks!

OK, Dave I know you were looking for me to answer this.' I had put together a circuit for my car to turn off the power amp after I shut the car off so I would not have to have a switch for it. After you shut the scoot off this will have a 5 second delay to disconnect the battery.  OK, OK, OK her is a parts list qty Desc. 2 1n4005 Diodes 2 100K-Ohm Resistors 1 10UF (Micro Fared capacitor) 1 1 UF (Micro Fared capacitor) 1 Zener Diode ( Voltage listed in Diagram) 1 SCR (Silicon Controlled Rectifier) TIC106D All Parts are available through Radio shack The circuit is designed to take the input voltage of 12 to 15 volts so the scoot will be fine. What happens is that the SCR acts as a switch until the two capacitors drain and then the SCR switch off. Every place you see a DOT is where the wires connect. If you change the two 100k-Ohm resistors to a lower level the time increases. |

WOW! Thanks for the detailed diagram but you might as well have posted it in German because that makes no sense to me. I have no clue how to make that. I'm "electronically challenged." I understand basic flow but I have no Idea how a blinker relay works for instance.
I guess I'm just gonna have to stop leaving the frickin' key on huh?
Yeah i'm a professional scooter mechanic but I don't troubleshoot electrical. I just replace the various modules until the friggin' thing works. :tongue:

I am in the same boat fox.. :stumped: Great diagram though for sure.... My elect. skills are worse than my tuning skills... :scared: :no: |

Sorry for being to complicated, I have now included a parts list and some instructions to help.
Your delay on your winshield wipers work the same way, the only difference is that they capacitors re-charge and the cycle repeats itself.
You may want to just just start taking the key out... :stars:

That does help some. I got a guy I hired to wire my bathroom when I remodeled it a while back that works cheap that can fill in the gaps if I decide to do it.
Thanks Jeff.

Hmmmmmmm. Well while he is qualified to do electrical he will most likely look at it and say what the !!!! is this...
If you are interested in learning more about electronics I would suggest going to Radio Shack and picking up one of their electronic kits where you can make several projects. This will give you a better understanding of what goes on and some very Kewl projects to play with.

I can read wiring diagrams for a car or scoot and make some sense of even that one, but I will never understand how everything functions. I have a Basic Electronics book from the shack but I get lost in there. lol

How about a new use for an old idea...LOL

If you change the two 100k-Ohm resistors to a lower level the time increases. Wouldn't lowering the resistances make the delay action shorter not longer? Won't the delay be present on power up too? |
