5.7 Alpha GenII Ignition Module
I have recently had to replace the Ignition Control Module on my 5.7 Alpha Gen II Mercruiser. The Boat is a 2006 Maxum 2400 SC3. I perchased the boat new in 2006. This the third module that has been installed in the boat. I do not know what is taking them out. The first two were warrenty work the last was on my dime. So I tore the bad ICM apart to try and figure out what failed. I did find a failed Diode, leading me to beleive a surge took it out not heat like the techs have been telling me. On a side note my batteries went dead over the winter and I had to replace them. However before I replaced the batteries I jumped the boat w/ my truck to get the boat engine warm to drain the oil better/faster. This may be the surge that took it out.... maybe. Anyway I have Pics of the torn apart Module if anyone is interested.
