Re: Swap from 1974 Mercruiser 3.0 to 1995 HELP!!! PLEASE!!!
Ntheyer<br /> what ign system are you useing? points, EST or DDIS ? all wire differently. and instead of talking posts lets label them. you have the main lug which is about 8mm depending on which stater your usuing. the small 4mm post close to the block is called the S terminal and should ONLY have a yellow with red stripe wire and the other 4mm post away fron the block that should only have a purple(sometimes) or purple/ yellow is called the R terminal. on the wire on it. The orange wire,if used, goes to the positive main lug on the starter soloinoid. the 10Gage red from the 50 amp breaker goes to the same lug.<br /> if you have any purple or purple yellow wires on the S terminal you will get smoke. but first we need to know what ign you have so you can make sure the shift inturrupt has been properly rewired. if not modified from the 1974 configuration it may roast the ign circuits if activated.
