Speedhut Dash Light Mystery

[cgundermann]

Just down to soundproofing/carpeting and I noticed my custom made Speedhut Dash lights do not illuminate anymore. Lots of threads on wiring these gauges to the Ron Francis (RF) wiring and I’ve spent the last two days under my dash checking and even reconnecting junctions to ensure they are solid. I have the Speedhut’s supplied dimmer/inverter and when I turn on my lights - my red needle on all of my gauges lights up and I realize that the FFR light switch I’m using only turns the needle lights on. When I turn the Speedhut potentiometer/dimmer - nothing. Every other function of all my gauges works properly. Dash light fuse is fine.

I have both the RF white dash lights (two with this RF kit; one to speedo/tach & other to the rest of the gauges) connected (guess I could have only used one) and they are spliced into the white Speedhut daisy chained wire and the white dimmer/inverter wire. The gauges and dimmer are grounded and the dimmer is plugged in to the Speedhut chain at the speedometer.

Multimeter at the potentiometer is showing close to 12 volts entirely through its turning sweep. The only thing that this non-electrician thinks is maybe the inverter module or potentiometer assembly?

Plan on calling Speedhut tommorow, but any thoughts are greatly appreciated!
