Thanks,   OR/VR is one of the things listed in E6 on the fuse diagram which calls for a 7.5 amp fuse.  It actually had a 5 amp fuse in it that was not blown and I replaced it with the correct 7.5 and it made no difference.  It could be the valve itself.  I'll do some more research.  Every small piece of  info helps to understand what is happening.
