Topic: 1970 Cb750 K0 Ko weird ELECTRICAL ISSUE running daily rider not a project bike

[RayWrangler]

HEY GUYS,

I HAVE A 1970 CB750.. WELL REG AS A 69 BUT ITS A 108 SO ITS A 70-71

bike runs fine, no issues but my odometer/speedo and tach lights went out, not the oil light but just the lights behind the faces.

also my rear brake light switch(spring on the foot pedal) went bad, picked up a new on on ebay......hooked it up and didnt work.. its the correct one, but when you press the rear brake lever it doesnt blink the light....inspection passed me anyway cuz i was gonna fix it.

but my blinker all work, and my headlight is fine, dummy indicator lights are fine, and the rear running light which also lights up my plate is fine too.

i did replace the main fuse, because it pop'd. oh and i replaced the winker fuse too

any ideas would help alot

K0 K1 BIKES ALSO ONLY HAVE ONE FUSE UNLIKE THE LATER YEARS. so i think

thx guys

Check the brown/white wires in the headlight. These serve the clocks.
