Rob, I have everything working for the New CDI as a single board....built the RCD version 2.3 programmer and it works fine..loaded the hex file, programmed the pic16f628 chip. installed a TIL111 optocoupler. Installed the PIC chip, powered up with the top jumper removed, got fast mode test just fine. Reinstalled the top jumper, removed the bottom jumper, got the slow speed test function working...unplugged the battery, replaced the lower jumper and powered up again. Tested the CDI with the hall effect and magnet..worked perfectly !! Thanks..

Only one problem afterwards...with all jumpers installed and battery plugged in, it shouldn't be sparking..but it seems like the low speed test jumper is removed and it gives a slow tick....tick...tick...spark on it's own...what should I be looking at, a bad part or is there a problem elsewhere in the programming? Any help would be appreciated... At least it worked perfectly the first power-up..thankful for that... I have used the LP2950CZ 5 volt low dropout regulator which is that same size as the BC557 transistor...it's rated for 800 milliwatt..should be fine for the chip power.. maybe the BT151 scr is leaky??? Had a few off spec parts give me that problem a few years back...anyway, thought you and the rest of the forum members here would have liked to hear a success story for a change.. It worked, and I owe it to you and JMJ for a great project!
