Hi Posted this on the wrong forum before. But this is the right one now. Anyway I am trying to help a friend get his motor going. The motor is a 1985 OMC 4cyl 2.5L or the 2.3L. The problem is when the ign key is turn the engine turns over but don't start. But if you take this wire on the coil which there is 2 on one side one is purple&black and the other is purple &red well if you take the purple and red and hook it up direct to the battery + side then turn the key the engine turns over and fires right up and runs great. Now I am wondering where does that purple and black wire go to. In order to make the engine run and fire. Not far from it is a looks like a soleoniod. It has 3 hookups on it 2 large bolts one with a red and white and a large purple on one side and on the other is a yellow and red. And above in the middle is a smaller nut and bolt with a smaller gauge wire which color is yellow and red. The loose wire coming from the coil which is purple and black is the same gauge as the yellow and red. Now the smaller gauge wire Y/R is running down to the starter. So at this point I know I need a wireing diagram. If anyone can help Please. I told him he sooner or later has to get a manual. So if anyone out there has a wireing diagram can you please post or I will give you my email. I just like to getting running right for him right now. I have pictures but for some reason I tryed everthing they just won't load. But if anyone wants to see them I can send in a email. Again Thank You for reader my post. Ed
