Am I Supposed to See 12V at the Tail Lights?
Re our Coachmen Freedom Express 192RBS:
I have a verified measurement of only 10.39V at my left rear tail light. I am producing 13.9V from my 7-pin connector on our Ridgeline at the tail light terminals. I've measured this under various conditions (connected to truck with and without the engine running; connected and disconnected from our 30 amp shore power).
My wife even noticed that our right tail light seems less bright than the left (measured something over 9V at the right tail light!). A couple of months ago I do recall having to replace our left bulb . . . seemed a little premature for a rig less than two full years old.
Eventual goal: tap in to good 12V DC to keep a rear view camera charged up while in transit. Seems like this wouldn't be advisable with this kind of power available at those lights. But this also seems to point to a larger problem.
Thoughts, anyone?
