Releew Posted July 30, 2023 Report Posted July 30, 2023 Flew today and noticed the Vac Warn, 1 amp breaker tripped. Would not reset. Started the standby pump and can hear it coming on. Any ideas to why the breaker is tripped. What device or devices are in this circuit? Weak breaker????? Why would the Vac Warn breaker trip when the Standby Vac system is NOT in use? BTW....I have solid Vac on the system with the engine driven pump....all good. Thanks in advance for any advice! Rick 377JF Quote
PT20J Posted July 30, 2023 Report Posted July 30, 2023 It’s almost never the breaker, especially if it won’t reset. This breaker powers the annunciator panel VAC HI/LO warning circuit. There is also a current monitor in this circuit that is part of the standby vacuum pump installation but it is not described in the service manual. I would start by disconnecting the annunciator panel to see if that allows the breaker to reset. If so, the problem is in the annunciator panel itself. If that doesn’t clear it, I’d next investigate the current monitor. 1 Quote
