Do you have a older DC with the gold plugs? If so clean them really good and get them nice and shiny... Use scotchbrite or steel wool.
I deal with headsets daily and this is the most common issue.
CLEAN THE DAMN PLUGS! LOL!
I bought my J-3 and actually paid top dollar for it. It was restored in 2014 and the logs start in 2014.
I could care less... I plan to keep it forever.
The last 172 I bought had a Wal-Mart Lawn mower battery in it. It worked great for years.
I giggled when it finally went bad and I saw what was in there. LOL!
I still like the 196!
It has the pointer :)
I just follow the pointer arrow to the airport. And it goes 16 hours on AA batteries! Great in the Cub and Stearman
Throw away all that greasy stuff it cooked in and put new sauce. That is how I de-fat it. LOL
It works great doing the same with boneless chicken breast also. Just cook less time.
