Thats a driver ign, Mercurys first AC selfcontained CD ign. system. Do not hook any connection to 12v. First disconnect the orange wire and ck for spark, the switch box really can not be cked even with a DVA so you must ck it for input and output the red wire (low speed winding) at the switch box should read 180V+ with a DVA or test 400 OHMs disconnected, the blue wire (high speed winding) should be 20V+ with a DVA or 10 OHMs disconnected, the white wire is a bond wire and should not be grounded and the green wire should put out 150V+
Thanks for the comments...By the orange wire you do mean the spark plug wire?Also I have checked the ohms and all checks out well.I have been told the swt.box must "cLick" I haven't heard the"click" but I am getting AC voltage to the green wire.I have no spark to the plugs..
before 1976 you have to have battery at 12v or more to get spark my 1972 80 will not start if battery is not up,if dist on it that, give's fact of power needed, problem might be pickup in dist.
gatorred, this is not the same type of system as your 80hp ign. this system is not dependant on battery voltage, eufaulaokie the orange wire I was refering to is on the switch box it is the ground off wire from the ign. switch--Bob
ok im wrong, then why my 50,1968 it would run right then gas it shut's off, then hit key it run's backward, the guy put dist on it, it was fixed but odd to me as why it did it.I have 50 and 80
gatorred, your 68, 500 used battery CD that the changed in 69 or 70 to driver ign. in fact I think your 80 and the 68, 500 use the same switch box. About the only thing that will cause a engine to run backward is that timing is not right<br />eufaulokie, sorry not trying to high jack your thread
