Infinity electrical issue?

On this years trip to Sturgis my 2000 Infinity WC coach developed what I believe is an electrical problem. While driving the coach with the cruise control on, if the V-10 would downshift I would get an immediate studded of the engine with dimming of the lights. Also when applying the brake to slow, headlights would dim and bolt meter would drop and fluctuate between 8-13 volts.
I'm thinking maybe a bad master switch not to be able to carry enough load through it. Or maybe a dead short to the system.
Any others ever see this?

Retired and loving it!

How old is your chassis battery and is it fully charged or charging normally would be my first question? If the battery is relatively new and fully charged, you might want to clean battery terminals/connections and main ground connections on battery to chassis; alternator and engine to chassis as a first check.

The battery is probably 4 years old. I did consider that as a cause and more likely the alt especially because of the drop in volts when signal lights or brake lights are applied. Thanks for your response.

Had a 2000 Infinity as my prior rig... Single significant problem I had with it in 4 years of ownership (bought used) was electrical...
Battery would discharge while driving - to the point of some weird things happening with lights and gauges - right up till it died... Had to swap batteries (I had a spare along for another activity) to finish the trip to campground - charged both batteries for repeat performance on way home (at least a planned 'pit stop' at rest area rather than the unplanned side of the road the first time.)
Thought it was alternator too - Shop (not RV dealer) found a wiring issue between battery and ignition - was more than a few years ago so not sure of the details...
Easy enough to get battery and alternator tested to see if they are ok.

Well, we are back on the road with no issues yet
(fingers crossed) I replaced the chassis battery disconnect switch, and the chassis relay in the battery control box. So far no issues with lights going dim or guages bouncing all around. Thanks for your replies.
