2005 Vectra. How does electrical selection work?
« on: November 26, 2017, 08:17:53 PM »
There seems to be no manual selection for generator, shore power, battery power.  My dimensions panel has no image displayed so I suppose that is broken but the genset works and batts charge (not sure the chassis is charging with anything but engine) but the house batts seem to be charging well.

Is there any type of manual selection?

The power defaults in order are (1) gen (2) shore power (3) battery.   

Your Dimensions Panel - you can carefully remove the bezel around the display, remove the screws and GENTLY ease it away from the wall.  There are a couple cables that you can check to see if they have come loose.  One of them talks to the circuit board that is inside your 120v breaker panel. There is also a 3 amp fuse on the back of the display panel that might have blown and can easily be replaced.

Basically no manual selection.  The power source is automatic, via an Auto-Transfer Switch (ATS). If the generator is running, it has priority as the power source and the ATS disconnects from shore power, whether the shore source is active or not. If you do not want the genset as power, then shut it off. That's your manual control feature.  ::)   If you want to use battery & inverter only  when shore power is connected, manually unplug the shore cord.  ;)

Battery power is always available unless you have activated the Storage disconnect.  However, when either shore or genset is active, the converter/inverter/charger system provides a parallel source of 12v power so the batteries are online but not really contributing. As soon as external power goes off, the batteries resume supplying 12v.

Your inverter/charger also has an internal auto transfer switch. so it utilizes external power (shore or  genset) when available but reverts to inverting battery power to supply selected 120v circuits as needed. If you do not want that to happen, you can turn the inverter off.  :)   Some inverters have separate on/off for inverting and charging, while others have only a single switch.

If not already done by a previous owner, you should add a Trik-L-Start to keep the chassis batteries charged up whenever the coach/house batteries are being charged.  Winnebago started adding the Trik-L-Start on the 2006 models, and this 2006-04 Trik-L-Start - (https://winnebagoind.com/resources/service/images/pdf.png) Service Tip describes the (very easy) process of installation in our older coaches.  [Note that the link in the pdf is out of date, but my link above is current.]
