My question is about the water heater in my 1996 Bounder which i just picked up. cant get the water heater working there are two lights near the switch above the stove. The one that concerns me says pilot on which i took to be the pilot light the light stays yellow and the heater doesnt fire. I did check and the gas is on and tank is full I thought this age water heater was direct spark anyone have any sugestions what i should check
