Our 1999 Beaver Marquis has had a problem with the voltmeter on the dash and the Silver Leaf system showing voltages from 13.2 to 15.2 volts, the gauge on the instrument panel constantly moving, headlights & instrument lights going bright to dim in a pulsing rhythm, warning light on the inverter control panel flashing on and sounding a alarm, and something else I probably missed. I read most of the posts about this issue, and had the alternator rebuilt (new brushes and regulator), but still had the problem. One or two mechanics and some of you in your posts suggested this could be caused by a bad ground. I cleaned all battery terminals and cable ends, but the problem persisted.
The house batteries have a red and black wire (probably 10 or 12 gauge) with ring terminals attached to the main 12v pos and neg terminals. I have no idea what they are attached to in the coach, but after close inspection I found corrosion in the wire near the terminal. I cut the wire back to clean wire and added new ring terminals. This fix seems to have solved the fluctuating voltage problem and now I have 13.8 to 14.2 fairly constant voltage and no alarm from the inverter control panel.
Does anyone know where these red and black wires go? I suspect the inverter or the instrument panel, but am not sure. The alternator is a Leese Neville model BLHA2070VE, with external regulator, and external ground. Is this what was referred to as a Bird system I read in a previous post?
Any comments, suggestions or possible answers would be greatly appreciated.
Thanks
