Help a retired geezer out - I plug a 2021 Tracker pontoon trailer into the Ram's round trailer socket? NO trailer lights work at all, none. The truck's tail lights DO function fine. but............ plugging the pontoon trailer into a 2013 Ford Explorer and a 2010 Chevy Traverse? All the trailer lights function 100% as they should. To further the mystery, plugging a 2008 boat trailer into the Ram's rear receptacle, either the flat plug or the round one? All that trailer's lights function 100%. So I am perplexed to say the least.
The pontoon trailer's plug works fine in two other vehicles, the Ram's receptacles work fine for a different trailer, leaving me to ask - "What the fergooglie?".
My troubleshooting skills tell me that the pontoon trailer's round plug and all its lights are fine, because they work 100% hooked up to the Ford and Chevy. The Ram's receptacles are fine because they light up the older boat trailer. But connecting the Ram to the pontoon trailer is a complete fail.
Can anyone point me to what might be the cause or need I hire me an exorcist?
Thanks for listening an YES, it's driving me nutz.
