I have a 2006 Beaver Monterey Laguna IV. In the past few months I upgraded my exterior running lights brightness by installing a kit from Daniel Stern (added two 30 amp Relays etc). Anyhow it was definitely a big improvement. Just recently I noticed while traveling in the coach my Dash Voltmeter is fluxuating from 14-16 along with my lights very gradually dimming a little, back and fourth. Everything Else (gauges, etc.) seams to be working ok otherwise. Shopuld this be a concern? Thanks

Check all the batteries in the system, chassis and coach , load test and electrolyte level, then check the actual voltage at the batteries, with the engine running to to see if the voltage reads out the same, on a different gauge , any voltage from the alternator in excess of 14.5 is considered overcharging and hard on the batteries, and 16 volts can easily burn out bulbs.

I had the same symptoms. Even the AC blower varied in speed. I found a loose connection on the back of the alternator that seemed to fix it. It was a small wire, nor one of the big ones. It was off the regulator.

Thanks for the suggestions, I will start at the batteries checking fluid level etc., then start working towards the alternator for loose wires. Thank you

If everything checks out, look at the voltage regulator. They can go bad and send voltages all over the scale. Sometimes the alternator itself is faulty.
