No...I didn't mean to offend...but the AC-CDI system has been used by all the Japanese motorcycle Mfrs since the early 70's This is a rugged simple design... it's best virtue is that it does not require a battery. check it out...it has nothing to do with inferior quality of design or performance...
I would have to say you are wrong...this system is called AC-CDI which has been used on dirt bikes for decades. I hope this attachment will explane this site gives component values and schematic. Rick:D
I have worked on fully automatic systems...like on early 90's Lincoln Continental That system uses a variable resistor to signal the controller. You may be able to do an analog system using the concept of a dampened fuel gauge system....where the gauge it has a current limiting resister across...
The ignition systems I have checked on CDI motorcycles have a 20v ac or so voltage at about 200 rpm to around 60+vac running then is stepped up in the CDI module somehow then discharged into a low ohms coil usually .5-1 ohm on the primary and about 5-6k on the secondary with usually 15-25+k...
this system's power source is a permanent magnet single phase dynamo with about 20v ac
at cranking rpm and about 60v ac running.the primary side of the output coil is about 1ohm.this triggering can be by virtue of the mechanical position of the dynamo coil or a separate trigger coil. Thanks
