Hi I'm trying to find a iso1 tach reader board, i believe it is a AG-0000033 mth board, is this the correct one, mine measures 17.12 mm is this the correct one or if any one of you guys have one i need it for MY Challenger steam engine. other question is the optic reader chip available from digikey or mouser or any other ic parts company, i do not see any part number on the ic!
Sincerely thanks for any help anyone can give!
