Hi,
This will probably be a little long winded..... Here goes....
I`m at where you were at 7 years ago, similar/same problem. Built a motorized bike, electric start, cdi, 12v battery. It got stolen, local pasty poor breeds, pic before the lights were added.
so I`m at building anothery. 80cc. The motor has an alternator built in allegedly. However, as I am adding lights, Headlight, taillight, brake light, indicators. 45w halogen headlight (huge 7" with built-in indicators, sort of grew on me may change it, for a smaller one like had before),
2-4w on taillight & 2-4w on indicators when they`re on, negligible. I might be being a tad of a worry-wart about it, however, It is alleged that the spark to the spark plug may suffer some performance problems.
Here is what I have at hand to use see picture:
& possible place to mount on motor drive chain side when installed, couple of pictures: {this is the 24v200w drive motor, it is harder to turn than the wiper/heater blower motor}
,
Using the wiper/heater blower motor, need to make a sprocket or find a bush.
End up making sprocket. {limit 5 images so, no sprocket}
Now, I`ve read a few posts, however, can`t seem to get the gist of some, 12v is 12v so, my thinking is along the lines of a voltage regulator perhaps from a vehicle, or simply a 30A or better, 12v charge controller like the solar charge controllers (example:
http://amzn.to/2oYRQvr on Amazon, can view on ebay or elsewhere too etc.)
Concern was/is overcharging battery, but again connecting it, both motors outputs have positive & negative bias, spin one way +ve, the other way -ve. No F or D markings, just black wire, red wire.
Any thoughts on the "solar controller" notion?
Thanks Guys
