QQ: How to wire new coils ? I am installing new coils in my 83QV USA spec, 308 and the OEM coils wiring connections are designated "15" and "1" my replacement coils wiring connections are designated "+" and "-". The wires are paired in Green and in Yellow. So.... -- what wires go where -- what is "15" and what is "-" ? I don't want to guess at tis or do a trial and error install if someone here has already done this and knows the answer to the wiring set-up. I checked the wiring diagram and it only designates "15" and "1" -- whatever those indications even mean?
There is a DIN standard for wire terminals. 15 is positive from the ignition switch. That is, it only receives positive voltage when the ignition switch is on.
wow! thanks for the quick response... I searched everywhere and couldn't find that basic info --- thank you again!
