Post Zuma 50 in FULL DC circuit, NO AC !!
Is this even possible without spending a lot of money ? If you say no, then stop reading and go find another thread.

Well, tonight I tested my theory and it does in fact work. With a MOSFET regulator at that !!! For around $30. I'm :D :D :D :D

Mosfet regulator used.... (search for the sub $30 one). These are 50A regulators which work at up to 30A when wired for our stator single phase. This is more than 4x the capacity of our scooter's stator capacity.

Wiring diagram shows how it was accomplished. Now LED headlights are possible !!!

Speaking of headlights, learned some few things today as well. The stock headlight bulb on it's own will DRAIN the battery when the scooter is at idle. This personally bothers me, especially for people who do the dual headlight mod. I tried these LED light bulbs into the stock housing and light output, while greater than stock is all over the place and not aimed.

Then just because I had it, I tried this light. ... ds=18w+led MUCH BETTER aimed output, and uses only 1/2 the wattage of stock. So now I want to put another one on for high / low beam and totally eliminate the bug eye look. Alternately I could could go :wth: and use a 36w light for high beam as it uses the same power as the stock bulb. ... ds=36w+led

Light outputs comparisons

PS, if using only 1 18W LED, you could simply get DC to it by tapping off the brown wire coming from the ignition switch. I only saw a 0.2V voltage drop at idle when using it (compared to .4V drop by using the stock halogen bulb). LEAVE THE STOCK HALOGENS UNPLUGGED IF USING THIS ROUTE as the light output from them would be pointless and they WILL DRAIN THE BATTERY is used at the same time with the LED light.

So, what does anyone else think ?

how much power are you saving by switching to full DC and only using LED headlights?
