Testing steering column Switches
I have a 69 with Tilt Tele.
I have the steering column out.
The ignition electrical switch was intermittent. I replaced it and checked it out with a ohmmeter..all good.
Now I want to check continuity for the turn signal switch, hazard switch and horn through the harmonica connector.
I can't find a electrical diagram shows how the switches are wired to the harmonica connector. I found the horn terminal on the G terminal. When you press the horn button it should have continuity between the G terminal and the end of the steering shaft. Its intermittent I have a bad horn switch.
But how do I check continuity for the other switches.
I also found the key alarm terminals E and F...checks out good.
Thanks for any help.
Mike

Checked out the flashers all good.
I read a high resistance on terminal J right front signal...
39 ohms.
And terminal N Right Rear signal..... 3 ohms
Do I need to replace the signal switch?
Horn is intermittent. Needs fixed.

Is my vette stock?? HAHA

If you didn't know, use a pencil eraser or a chemical cleaner on the contacts for best results, be careful of your paint and anything plastic with the sprays

what is a acceptable for a ohm reading between the Horn Terminal G on the Harmonica connector and the shaft of the steering column..... I'm reading 430 ohms when the horn button is pressed.
Thanks
Thanks

Since this is a simple (from an electrical point of view) contact, it should be close to 0 Ohm.
But from a mechanical point of view there are a few components involved which might sum up to high ohms reading (when corroded / stained / weak).

Are you sure you have a good ground for the measurement (steering column shaft properly grounded)?

I think I have to remove the plunger to inspect it.
