Added gages:

Upper left side: Generator fuel gage (gasoline)
Right side cascade: Tranny temp, EGT, Boost

Oh boy… left side top: lights, wipers
center rockers: clearance light flasher, "aux start," fog lights, aux electric engine fan, defroster fans

The speedo is a custom Speedhut GPS, tachometer also Speedhut.

Below the panel on the left side are the controls and gauges for the tag axle air bags.



right side top: vacuum gauge, spotlight control joystick, spotlight indicator lamp, spotlight selector switch
rockers: aisle lights, docking lights, fuel tank selector.



"Experimental area:"

OEM Chrysler heater "controls" don't really work. A vacuum selector system with manual zone valves is planned.

The warning lights are red (no oil pressure) and yellow (check engine) LEDs.

Generator start and stop switches, fuel pressure gauge, air pressure gauge, air compressor switch.



This area is obviously still under construction.

How do you like the GPS speedo! My stock speedo reads about 12 mph high and would like to change out for a GPS model.

I am very happy with the Speedhut GPS speedometer. You can choose the style of the numbers, the needle, the speed range, the colors,etc.

The speedo is always within 1 mph of the other GPS I run. It is smooth and steady. Only down side it does not work for long in a tunnel.

In the data window you can get odometer, trip, time, altitude, compass heading, 0-60 time, 1/4 mile time or top speed!

I chose the scale range of 0 to 80 mph for mine. (Somehow the top speed says 92…)
I guess I was hauling down those hills in Tenn more than I thought…

Doug,

another subject -- Rusty says you may have an answer on this.
what happens if the house batteries are wired in series (24v) on a 89 Regal? have nothing coming on in the house circuit. is there a simple short fix for this or are some circuits burned out?

thanks

Dave

24V will fry the control boards for the reefer, water heater, furnace, and A/C. Lights will burn out.

Check the master switch. The relay it operates may be bad. Battery voltage should be at lest 11.5V (which is near-discharged at that level)
