I'll have to try that on the next one that comes into the shop.
I suspect that there is a battery on the power board that eventually goes dead. Mine had no issues at all for the first 7 or 8 winters by the last 5 or so it's taken it's time to start and then it's fine for the summer. Once plugged in for a bit it seems to regain a charge and then the machine works fine until I winterize the cabin and shut the power down.
