Topic: Gauges won't light up at night..

[whp]

Here's the issue,

The backlights for the gauges won't light up when the bike is turned on or running. If i put it into parking position they will light up, but otherwise they its just darkness.

Figured I'd bounce a few ideas off of your guys mind.

Bike: 1978 CB750K


1) They are not supposed to be lit at night, a special feature on my model that discourages nighttime driving.

2) Fuse or Relay

3) The wires don't complete the circuit at the RUN position.

 


I've searched the forum, but I havn't found anything common about this problem.

If I can't figure it out i'll just throw some LED's in there and run a toggle. Call it a day at that.

Thanks!

because it works in PARK, i suspect its your key switch.  remove it and clean all your connectors and contacts for it.
have you cleaned all the other electrical connectors in your harness?
if that doesnt fix it, remove your headlight from the fork ears, so you have access to the wiring.
at night, or in your dark garage, turn your key switch to ON, and start methodically wiggling each connection, and the block connector beneath the ignition switch.  if there is a bad connection, you'll find it.

I'm with flybox about the switch. If they aren't wired up right then they just wouldn't work. You got something that is coming loose when it is running/movign
