Not to jack a thread- but you guys have done this soooooo.........
In all your diagrams, the C70 and/or puch lighting coils it's one coil. In one end out the other. But I'm doing this to my hobbit- want to go rectified DC with a small battery. Problem is with the hobbits 2 coils and different grounds, I'm at a loss following the ins and outs hehe.
I'm not gonna lie- An electrician I am not. Wired houses, wired cars. AC and DC I get standalone- It's the mixing of the 2 that has me a couple questions.
I have some stuff here- 2 different Hobbit CDI Stators- A Chinese 4 wire rectifier- A 77/Treats heavy duty voltage regulator(2 wire), a whole mess of incandescent and led bulbs, and a Powercap Battery which is really just 2 rows of caps and an overvolt led. Never have gotten a thing to power off that cap battery- but maybe we can use it here. Pic:
I have wasted so much time trying to figure this out on my own, I went ahead and pulled both stators apart to clearly see the windings, connections, and coils. This should be helpful to me and maybe others later if you guys have suggestions or comment on the pics.
Let's start with my first CDI, otherwise known as the cheapie 77. This confused me because it's 2 coils both with separate grounds, and a ground wire. I took the tang off one coil and soldered a small wire onto it for testing purposes, but wondered if I wanted that one floated to the rectifier, the other one, or both? On this one the primary lighting is red, low power is brown, green ground:
Then I bought another cdi stator from 77, it seems like very poor quality, so I'm calling it the super Chinese 77, but it's 2 coils are wired differently there's only a ground tang on one of the coils- and all 3 wires on it are on the ungrounded coil? Again the 2 coils are connected together like the other, but this one has a grey primary wire, red is the low power, and green ground wire:
Of the 2 which would you use? Which wires would you connect to what on each of them? And given the choice I think I'd rather use the cheapie unless the super Chinese would be an advantage from a wiring standpoint. I'll say this- the superchinese barely put out 9vac on the grey, like 2.5-3vac on the red(both unregulated when tested)- but my good old cheapie puts out 30vac on the red if unregulated. Somehow the superchinese seems like it would have to have a rectifier to ever work- but I'm probably wrong as I usually am! (edited)
