Yes the rocker switches at the helm. If you turn them all on and the overhead light does not come on you have a bad bulb. I'd recommend starting there.
On my 2800 SCR, the Courtesy Lights and Arch lights were separate switches. Both on the left side of the helm. If I remember, they were both labeled Accessory Switches.
Thx will look over the weekend, remember they were working last year, maybe bulbs or fuse blown. Wish there was a good fuse circuit layout diagram, previous owner has made quite a few modifications. Making notes as I find out which fuse covers what!
Quick question do you have the JRC-Radar 1800 on your 2800SCR, reading the manual puts me to sleep, wish there was a short idiot's guide just so I can use the plotter.
