Hi all, sorry for hijacking this thread, but I can't find how to start a new thread......
I have a markVii 7 GT-700. I am getting a top boom error about 1/3 of the time. The error always occurs as the boom is making its first drop on the front end of the car. The boom fails to fully drop and tilt, and then completes the was with no boom tilt or drop. As this only happens at the front and first boom drop, the thought was there was electrical noise when the tank fill solenoids activate. We added MOV 25v RMS "diodes" to the fill solenoids on both tanks. Washed over 6 cars with no issues. Then as I leave wash the error codes begin again.
THOUGHTS??.
