Tighed1, that is what I looked for when I took my RCM apart. Didnt find any burnt contacts. (Still think solid state relays would be better). I did re-solder ALL the connections on it though. I still had the intermittant no start so I swapped between the SSB and the Aero. I still have the intermittant no start on the Aero. RCM ruled out as cause of my issue.
