Hello DC0046
I had to look online to determine what your coach looks like, since I have a Newmar. From what I saw, the high beams are controlled from the traditional Ford "stalk" on the steering wheel. This is merely a switch for a high current relay, since high beams do require a substantial amount of current. This leads me to determine which component is causing the problem.
1. Fuse
2. Relay
3. Switch (in the steering column)
Since this is a fairly new coach, I would call Winnie Industries up and find out where the fuse and relay are located. The relay could have become loose. Beyond this, a little electrical knowledge is necessary with a good volt meter. The easiest way to determine if the column switch is working is to measure the voltage for the coil of the relay. This would require a couple of wires inserted into the socket of the relay and switch the high beam on an off. If no voltage is present, then the column switch must be replaced. This requires to pull the steering wheel. If this is beyond your capability, you will need to get it into a shop.
Best Regards
Dutch Master
