After posting yeasterday , I checked the fuse. It looks good. I didn't put a meter on it yet, but will later on. I think I will check the wiring next. I used crimp on connectors and thought they had a good bite, but I may rework the connection and solder everything. It may very well be a bad connection since the boost quit all at once like someone turning off a switch and never kicked back in. We'll see.-Rusty
