Hello, all -
We have a 2016 Thor Hurricane 34F, and I recently had something odd happen in the electrical system that I can't explain. All power from shore, batteries, disappeared, and nothing worked until I disconnected the coach batteries and apparently everything reset itself. I checked the coach batteries, and apart from needing some water they had 12.4 to 13.2V. After reconnecting everything, things are fine, except...
During troubleshooting, I thought there was a problem with the transfer switch, so I tested voltages into the transfer switch from shore power. Power was coming in, but the transfer switch had not connected, thus nothing going out. Suddenly--as I was checking the voltages--the switch kicked in for shore power and the RV came to life. Scared me as it was unexpected. 120V was now coming out of the shore power relay on each side of the circuit. All normal.
The manual and label inside the transfer switch case says there's a 20-30 second delay before kicking over to generator when connected to shore power but we were connecting to straight to shore power. It now seems to take 2-5 minutes for the transfer switch to engage for shore power. That's the new development. The loss of all power to everything and this new behaviour seem too coincidental.
Could there be electronics with the relays and other components that are causing the slow engagement to shore power, i.e. the unit beginning to go bad?
Thanks for your time.
