I have electrical problems and cant find the cure. 08 Sabre, 150 ETEC- Flyswatters old Sabre Motor runs and all four I-Command gauges function. -No A10 power(bilge, lights, horn, etc), GPS or radio. Master panel light does not illuminate. Tried the “red” reset button. I pressed every inline breaker I could find coming off the cranking battery. I have a loose purple wire underneath. Cant find the missing end. Where is the main line circuit breaker in the back? Any help would be appreciated. Adam
