I think I have a bad circuit breaker coming off the cranking battery in-line to the main power switch on my 2000 Pantera Classic. Trim & gauges all work but Sonar/GPS and all accessories that run off of the BP2000 shut down. I found that the ciruit breaker in-line at the battery is tripping and I cant find any loose connections and sometimes when it trips it wont reset. I cant find an amp on the current breaker to know what to replace it with, what do I need to get? I appreciate any help you can offer.
