#112120 - cleaning input signal from the spark plu Responding to: ???'s previous message |
1) I hope this is a mistype, you do not plan to run of a spark plug, do you
2) assuming you are referring to the low side of the coil, you will need 2 things protection and noise suppression. For protection use a zener together with a transzorb with a slightly (.5-1V) higher voltage rating. You will need a suitable capacitor across the input as well. In many (most?) cases you may find that you need to opto-isolate the signal. This is not "easy street", an engine compartment is a very noisy location electrically. I suggest you read the FAQ on noise and follow it. Erik |
