Can you stable out a 12v dc pulse?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of stabilizing the output from a 12v magneto, which produces pulsed DC, for use in a go-kart's turn signals and brake lights. Participants explore methods to convert the pulsed output into a steady DC current, considering components like capacitors and diodes.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant inquires about the type of turn signals (tungsten lamps or LEDs) and questions whether pulsed output would be suitable, suggesting that a diode and capacitor could effectively stabilize the current.
  • Another participant suggests using a battery charger coil along with a bridge rectifier and a large capacitor, referencing historical use in British motorcycles to operate without a battery.
  • A participant seeks clarification on the original purpose of the magneto and what information is available on its plate, indicating a need for more context about the component.

Areas of Agreement / Disagreement

There is no clear consensus on the best method to stabilize the pulsed output from the magneto, as participants present various approaches and considerations without resolving the effectiveness of each method.

Contextual Notes

Participants have not fully explored the implications of using different types of turn signals or the specific characteristics of the magneto output, which may affect the proposed solutions.

Hey guys. I made myself a pulse circuit but my power supply failed.
Now I need a way to use a 12v magneto as a power supply.
But a magneto puts out pulses. Can I put a capacitor or a diode there to make it a steady stream of dc current?


This is for my go kart 5hp briggs. for turn signal and brake light

Are your turn signals tungsten lamps or LEDs? Is there any reason pulses won't work? Yes you can use a diode and capacitor very effectively.

edit: id like to still use Leds and my timer circuit to get the blinker speed correct and use the magneto as the power scource

LEDs still sorry wasnt thinking straight
 
look at the battery charger coil on any electric start lawnmower engine.

one of those plus a bridge rectifier and huge capacitor will do what you want. 1950's British motorcycle guys used this technique to avoid having a battery. look up how a magneto works...

For what purpose was this magneto, originally? What information does it provide on the plate?
