One mistake people make about dielectric grease is - it is an insulator..as in it does not conduct electricity, which is good but sometimes the application of it on electrical connection it can get on the pins or swards or receivers and if..if the connector can not scrap it all off and make a metal to metal connection, it accidentally has a barrier between the two parts and that becomes a problem...especially on low voltage connections. Dielectric grease inside the connector around the the connection area is fine for keeping water from getting from the outside to the connection area...but there should never be any on the connections themselves. Most times it isn't a problem cause it scrapes it off enough to make a connection. But sometimes...it can't or doesn't. In the water and mud world I have long been an advocate of just putting a paper-thin coating of electrical-grade RTV around the outside of the plug to seal it off and not use any grease. If you think any of your connection has grease in the connector(s) blast it out with Braklean and Electrical Contact spray cleaner. Do a final blow with air and re-do if any is seen coming out.
