Drove home from Buckhorn Lake RV resort. 320 miles. Jacks worked, but air pressure gauges kept bouncing to zero, then back to normal. Both gauges dropped at same time. Stopped at Three Rivers Loves for diesel. Strong SE wind plus drizzle thru San Antonio. Arrived home around 3:00 pm.
I took the dash cover off and tie wrapped the bundle of wires below the gauges. Re-connected wires Into gauge. This seems to fix intermittent problem.
