Xantrex Trucharge 40, now about 14 years old, replaced as part of a lightning repair on this 20 year old boat. This weekend, for the 3rd time in 9 months, when I plugged into shore power and flipped on the panel breaker, the charger failed to immediately start up despite the voltage being down below 12.6v. Normal behaviour is that it immediately starts charging, as indicated by the Link 20 volts/amps and the sound of the cooling fan. All other shore power circuits working as normal. I flipped the panel switch on/off several times over the course of a half hour or so. Then I left the boat for about 6 hours (leaving the charger circuit turned on) and when I returned found the batteries fully charged. Of the three failures, two have recovered like this, one time, I started the engine and the charger came on.
Thinking through what might cause this, I believe it could be the breaker on the shore power panel, the connection there or at the battery charger, or the charger itself. Any ideas how/where to troubleshoot, or should I just wait for something to stay broken...
