Gauge lighting

[Hemifish440]

Have an early 944 and I am having two issues with the instruments in the center console. First I am replacing bulbs but not getting any power to the clock or the oil gauge for the lighting. Check bulbs both directions and same issue. Also the oil gauge drops to 0 when lights are turned on but reads fine when lights are off? Is there a specific fuse for console lights? Lighter clock and oil works (lights off) so not sure its a fuse.
