[Roadsters] Fwd: Re: Gauges....

[Bill Yoder]

I would like to ask another question along this line. My dash lights do not
come on at all.
I have a '68 2000 and have two knobs on the dash. i assume one is for
resetting the trip odometer that does't rest. The other I
Assume that it would be the dimmer switch. One turns and the other does not.
First of all, I can't determine which knob is which. Then I need to figure out
if the lights are burned out or is there another problem like a wiring issue.
Any helpful thoughts would be appreciated.
Thanks, Bill
