Alpha Classic Ignition

Let me start by saying that I love this ignition and have it installed on my R90s for 4 years now. So I had the final drive, swing arm and gearbox off the bike for routine maintenance and when I reassembled the bike it would not start. Tracked down the issue to an intermittent spark. Checked my connections at the coils (reseated and cleaned) still no joy. I pulled the connector on the ECU and this is what I found. Still puzzled that 3 terminals showed signs of corrosion as there is a gasket in the connector and that the assembly is mounted directly behind the coils in the recommended location. Cleaned and applied dielectric grease pins and the bike now runs great.
