warning lights flashing

The warning lights in my 99 discovery flash in counter clockwise direction. I have checked loose wires per freightliner tech, disconnected wires to dash panel, stopped for 2 days. Disconnected batteries over night lights quit flashing for 5 days. Would these lights be enough draw to kill batteries in 5 to 7 days. Chasis batteries seem to go dead even with shore power hooked up. I have seen several threads but no solutions, HELP.

jgh many coaches have no charger for the chassis batteries from the shore power. The easiest inexpensive remendy to keep them from going down is to install a Trik-L-Start Ultra TRIK-L-START Starting Battery Charger/Maintainer.

I have seen the lights doing the counterclockwise pattern when my cranking batteries were undercharged (low voltage).

Info from Freightliner says it may also be loss of data going to the message center. Quote from Freightliner SB 54-12 below.

Message Center (MC)
The message center (MC) is located in the dash panel and contains the icons that illuminate to warn of potential
problems. See Fig. 1. The MC has a built-in diagnostic function that indicates whether or not the MC is receiving
data from the vehicle data computer (VDC). If data is not received from the VDC for more than 45 seconds,
the icon lights will "dance" or initiate a chase pattern, indicating no reception of data. Data is sent from
the VDC to the MC and on to the instruments. See Fig. 2 and Fig. 3.

If you need the entire service bulletin, see the link below
