When I am plugged into shore power my battery only charges to 13.2 volts. Never seems to go lower than 13.0. When we returned home yesterday after only a 25 minute drive it was up to 13.7 volts. Same thing happens when it is plugged in at home. Never more than 13.2 but once I tow for a while it charges to 13.7. Any ideas or suggestions for troubleshooting?
