Have a Mercury 80 hp, 4-cylinder, 1972 with the famous thunderbolt ignition system which includes the "dead" switch box and the distributor which feeds same. Being poor, I <br />wish to "duplicate" the box if possible. Anyone out there who even has an inkling what's in the swith box and/or distributor? If I can find out, I'll be delighted to share any progress <br />I make. My background as a retired electrical engineer should stand me in good stead here... <br />What say ye? (I do have the Page 3G-9 of the manual but it just shows pictures, no actual wiring of individual items.) Jim Reed.
