I need to know the correlation to speed so that the rally computer's internal counter doesn't overflow from too many pulses. An adapter that turns the AC wave into a square wave is a piece of cake, but it gets more complicated if I need to make it a divider, too. I suppose it would be nice to know what peak-to-peak voltage levels to expect, but with a 12V system it can't get too outrageous. If worse comes to worst, I suppose I could hook up an oscilloscope to it and just measure the damn thing.
All of the wiring diagrams would be great to have, as would a real factory service manual like I have for my 123 and 201 chassis. Any tips on where an owner can procure them?
By the way, I really appreciate the time you've taken to look this stuff up for me and to relay the information to me here.
Very Best Regards,
Rob
