Update…..here the score card on our electronic valves passing and failing. Eight trips completed. Five successful dumps and three failures. Last failure fall of 2014 occurred in eastern OR at Farewell Bend SP and we were headed by the mfg facility at La Grande, OR so I called the service advisor and told him I was going to stop by the factory with my load and let them sniff out and trouble shoot our dilemma. That did not set well so he arranged to have me go to a repair center and a good tech swapped switches and we dumped successfully at Wallowa SP. Yes things are improving and time will tell!
