I have OMC equipped 574APERGD GM engine powering my King Cobra Sterndrive. The Engine is a crate engine and not original. Has Marine carb Holley 650 Electric Choke, Vacuum Secondaries. I removed it to install a kit. I noticed that the Purple/White Wire was connected to the EX terminal on the alternator. This conflicts with the OMC Service Manual which shows the Purple/ White wire for the choke connected to the AC Tap on Alternator.
1) Is the Manual correct? (I realize that sounds like a really dumb question). If so, then I wired it incorrectly a couple years ago while trouble shooting another problem. I took the alternator off to get it tested and reinstalled.
2) If the wiring has been incorrect all this time, could that explain chronically rich running carb?
See pics of the choke wiring as it has been running and the pics from the OMC Manual. I attached the wiring and legend from manual.
