So hopefully I'll hear from him this week.
If anyone has someone else's bench to refer me to (I know my limits ), let me know. SEAL in Orlando still have a bench?
I'm proud to say I'm ahead of you - I took my can of D5 to the shop with me and sprayed some on those spots on the back of the switchboard that looked like they were leftover flux, and I pulled each end of each ribbon cable off and sprayed some inside the connector and then pushed them back on and worked them a little bit. Didn't have any Q-tips.Just for giggles, try reseating the ribbon cables. If you've got some De-Oxit, a little on a q-tip to clean the pin headers would be a nice touch.
