Lack of instrument panel warning/information lights

[GSJon]

Hi all, got some problems with my 1977 GS550DB (twin disc, spoked wheel,rear drum). Put a battery on her and have turn indicators and dipped and high beam showing and working. However no oil pressure red light in the panel and no neutral green or gear indicator showing. Have cleaned oil pressure switch and have cleaned gear selector unit above front sprocket. Nothing happening. Not sure if they have had it, or it is a wiring issue. Any thoughts greatly appreciated. Ta!

Maybe just the bulbs are blown in the gauge cluster.

Hi,
thanks for that, eventually managed to get the bulbs out to check the and they all seem ok! Guess its back to slowly tracing the wires and see what is occurring.

Had the exact same thing happen on my 1100. It was a poor electrical connection. It was in the ignition switch circuit. I never got to find out how the poor ground was not making properly. However, mine actually cleared up by "exercising" the switch to clean up all the connections. I don't know if I have a permanent solution, but do know that it was just a loose ground for those indicator lights. All my bulbs were fine too.

Thanks Larry J,
Very helpful.
Time to start the journey that is the wiring loom. Wish me luck on my quest!
