64 No power any where other than "Batt" on ignition

Hey guys and gals.

So I am building a 64 C10.
Put the front clip back on and connected all bulk head plugs, battery, starter etc.

I had no power to any of the truck. Pulled out the meter and started checking wires. I found a bad connection at the battery to the Horn relay / Voltage regulator.

I fixed that and wha-lah! I had power everywhere. Lights, dash, etc... all good.

Hit the key to start the truck and as soon as I had it in the start position.... I hear a noise as if a relay or something clicked (definitely not the sound of the starter solenoid) and NOTHING again.... No power to lights, dash dummy lights, horn, anything....

SO I started tracing power again and have found it was not the same problem as before. I have power to the horn relay / Voltage regulator, then through the firewall to the ignition switch on the "BATT" terminal. and thats the end of it.

I turned the key to the start position and checked the "SOL" terminal to see if I was getting power to the solenoid and I have nothing there. This leads me to believe the ignition switch is bad....?....?

It then dawned on me that I have no power elsewhere and a bad ignition switch doesnt explain that.

Could the Voltage regulator and the ignition switch both be bad? Its not common, but the truck ran a month ago with no issues starting or running.

I know the system isnt that complicated (relatively speaking) but I am not familiar with it yet.


Thanks all!

check the bulk head plug "hot" goes from the horn relay through the bulk head plug the branches to the fuse panel, light switch and the ignition switch http://67-72chevytrucks.com/vboard/s...d.php?t=193429

Checked that multiple time, though it is next in line youd figure.
However.... the power is getting through there, now that I think about it. I know this because its getting to the ignition switch.

Does the pwer split to the fuse panel at the voltage regulator? Or after it gets through the bulkhead plug?

I have diagrams, and have been trying to put it all together, I am hoping some experience will chime in with a common issue for these trucks.

AFTER... that's why it is not making sense that you have power to the ign. switch and nothing else

Yeah I am seeing on the diagram that it splits to the light switch, and the fuse block. Ill have top trace it that point I guess. Haven't had a chance to get back to it this week.
