Actually for the transformer being its working a center tapped voltage bucking mode you can get 5 amps out of a 2.5 amp rated transformer being its only stepping down half the current and half the voltage at the same time on what is essentially one winding supplying 2.5 amps from each end to get 5 amps in the middle.
Hmm...I got u. I need a buy autotransformer or a simply powered center tapped (12-0-12)(3 amp) to use as a autotransformer.
Here is my current
**broken link removed**
I read on other forums, the guys who are talking about using the full wave....its nothing!
what they have is......they removed the ground (green wire) from the bottom of the lightning coil and pulled that yellow wire from the center and connect to that end & they use that both wire to give power to Ape RR unit to convert the bike to full DC. Waste of time and money.
So what I've done today
I use that full wave via white wire and body ground and connected the hand made bridge rectifier with 6A4 diode + 4700uf 35v capacitor
and the marked more than 45 VDC in just a half throttle (I don't have tachometer so cant tell the rpm, i also looking forward to create the digital of it but will discuss that later, my current aim is to have 60w bulb).
So coming back to the point....when I connect the bulb, I marked the readings of 5 amps and 12 volts
the volts dropped from 45 to 12 volts but this figure bring me the smile
my hope has not gone, I still have it.
I was not driving this time, on the stand position, without any load.
That white wire is used to charge the battery & this battery requires only 260mA (as per its manual).
So i'll still have at least 4.5 amp for bulb. All i need now is regulator. Can't say about rectifier.
I created using this
**broken link removed**
and its working, not yet tested with 60W load, but I think it will need some modifications. Just a Zener.
What you say? Do I still need the transformer? or this can be done without it?
Edit: I missed something....I've to test again, if I use the yellow wire to charge the battery with same rectifier....would there be there enough power available for the bulb...doubt
