Have a 1986 MerCruiser with the 3.0 L was having many problems with the Distributor so I decided it was time to upgrade it the pointless Distributor, so I went with EST Delco Distributor and coil. Bought the whole conversion kit. Problem is I'm having troubles wiring it. The instructions that came with it I don't even see why they wasted the paper they were the worst instructions I'd ever seen. So, I got upset threw them away and walked away from the boat for a couple weeks to claim down. I thought I could find something on the internet, but I was wrong I cannot find anything really about it or a good diagram that is simple enough to get it done the right way. I have read a lot and learned that the coil needs 12v and no less so the purple wire cannot be hooked to the coil, if I'm even reading that right. I am now desperate to get it done because I live up north and the temps are dropping at night. Anybody out there that can guide me through getting this wired up or a simplified wiring diagram would really be a big help. Wiring is not my strong point. Thank you for anything you can offer.
