Just bought this 2005 Campion Allante LS645 this summer and have had it out about 10 times. Last week took it out for a week and the last day at our spot on the lake the boat wouldn't start. The batteries were both fully charged. here is the sequence of events
- plugged in USB adaptor to the cigarette lighter plug. the adaptor came apart as I plugged it in, so metal pieces were in the plug. I shut the power off, fished them out.
-few hours later went to start and there was no power to the bridge/helm at all.
-checked the breaker panel and none were popped out
-checked all fuses that I could find and they were all good
-called a mechanic and he came over and checked power and ground between the battery and helm which were good and measured batteries at 12.7 volts
-The trim and fishfinder work/have power (separate circuits obviously)
-we tried to trace wiring and find a hidden main fuse but couldnt.
I was hoping someone would know where or if there is some secret main fuse. or maybe had this problem and knows where to start!

welcome aboard.

start at the big circuit breaker at the motor and then work toward the helm
