10.74 AC Volts from the generator, 13.9 DC Volts from the Pit Bike Rectifier/Regulator.
To find DC Volts from an AC source and full wave rectifier and smothing capacitor, multiply AC volts by 1.44, less 0.5 to 1.0 Volt for the forward resistance through the regulator........
Hi Koba, as you know, we made our own generator by rewinding the ignition coils so they put out about 14 Volts at 2.5A and used a cheap Pit Bike rectifier regulator to charge a 12 Volt battery.
We used one of these jell type batteries they work well on the CB125T's up here at Mt Welly, but the vibration of our 2-stroke killed it.
So in a moment of brilliance I grabbed the 14 Volt battery from a Black and Decker battery drill.
Worked great, lasted all day on the dyno, then after a while the battery lost power and the ignition started playing up.
When the 14Volt batteries voltage dropped the ripple voltage from the generator was false triggering the ignition and we were getting multiple sparks per revolution...... and we could easily see this with a timing light.
It only took Thomas and Bucket a few moments to relise my mistake.
A 12 Volt charging system dosn't work well with 14 Volt batteries......
Our next move is to try a capacitor instead of a battery, a 24V 100,000 uf electrolytic should do it, our IgniTech ignitions will run any where from 10-18Volts and draw about 0.2A at idle and 0.8A flatout, so the 12 Volt charging system and capacitor could be OK.......
