My neighbor decided to clean his engine with Stoddard solvent and a cyphon sprayer. This is the usual way to clean Lycoming and Continental engines. Several days later he tried to start the engine and it would not start. The only thing done to the engine since it was running fine was the engine washdown with Stoddard.
It did not produce any spark at all and never even tried to start. We opened all the module connectors and all looked clean. We reconnected all the connectors and still no fire. I had a spare module and we installed that and the engine started and ran fine on both/either of the modules now. Next we reinstalled his original module. It ran fine now with both of his original modules. We concluded that all the unconnecting and reconnecting of the connectors must have wiped them clean.
So, now what is the best procedure and product to clean the connectors? Also, if stoddard solvent will contaminate the connectors what about flying in rain? Any ideas about this will be greatly appreciated.
His engine is a 912ULS 2007 model with about 600 hours on it.
