![]() ![]() Some hacksawing or dremel cutting wheel work may be needed to gain inside access. You are going to need to shield your circuit, filter its supply, and will also probably need to use multiple layers to shield its traces.Ī few dollars and a few minutes at a wrecking yard will get you plenty of examples to examine. The 7805 has a.33uf cap from 12v to gnd and.1uf from 5v to gnd. Welcome to AAC Id suspect the supply decoupling and spike suppression arrangements. Im not looking for anyone to solve this problem as this has been a very complicated project, im just looking for some fresh ideas on how to approach this problem. Build An Ignition Coil How To Approach This I am not sure if I am getting some sort of feedback from the spark, or inductive kickback from the igbt or the mosfet. The third is the VAG coil which use a mosfet and draw around 600ma. Then second set of coils are the nissan p12 coils, these use an IGBT and draw 20ma as well. These use either an IGBT or mosfet, but draw 20ma of current. ![]() It seems that when the spark event happens, one or all of the ICs are affected even though all the input signals from the cam sensor are not distorted. I thought the glitch was isolated to my printed board so I installed the protoboard and the same thing happened. What I observed is that the board was able to identify TDC of the 1 cylinder, just as its designed too, but upon the spark event, the board glitches and is thrown out of sequence. On the bench the board tested perfectly and sequenced exactly like my protoboard and used all the same components. I found and corrected the error in my schematic and decided to get some pcbs printed for quality purposes. The protoboard worked great and I was working on making my own pbc via etching and when complete and hooked up, I had a short and fried my pcb. Download renaissance pushim rar free software The goal wasnt to produce more power, but to eliminate the mechanical aspect in the ignition system. So when I hooked up the printed board, the car would not start.
