67 C20 no electrical power - help!
 

I picked up a 1967 C20 a few months ago with 68700 original miles one owner. I am proud to be the second owner of this old work horse! It has been used but always in a shed and has zero rust! I replaced the points distributor with an HEI about a month ago. Ran great till the other morning. I turned the key and turned the engine over a half revolution and I stopped because I had forgotten to turn the choke on. When I went to turn the key again there was no power to anything. I am assuming it has something to do with the voltage regulator but I am not sure. I did a little trouble shooting but I am not sure what it is yet. That is why I am checking with you guys. What do you guys think it is? I will have to post some pics of the old green bean soon.....

i'd check the battery cables first for good clean tight connections// just lookin at them doesn't help

also are you in park or neutral?
when installing the HEI did you run a new supply wire for proper operation of the HEI

Re: 67 C20 no electrical power - help!
 

Yep, I tried that right away and they were good. I put a new battery and cable ends on it right when I got it. I checked power to the starter post and I have power to that point. I do not have power to things like the dome light and horn, etc. Could it be the regulator and what would have caused issues with that?

No I dont think the regulater would do that. If I remember corectly the + cable goes directly to the starter but there is a red wire that powers everthing else in the harness. its like a 10 gage or maybe even an 8. before it gets to the fuse panel it goes to a terminal block on the fender I think and also If I remember right it also goes through the horn relay before the fuse block also.try tracing those wires looking for breaks and bad connections.

if your have a true 1967 truck they used that horn relay it run the hole truck all the power gose throw that one relay to fire the truck On my 1964--66 chevy trucks when i get no power i change or unplug and replug the Horn relay back in.I have a 1967 3 door suburban not sure if they carried the same design over to the 1967-68 modals but i would check there first before i go tearing apart the truck here is a picture of what i'm talking about NUMBER 1 is too my 1965 and number 4 is to my 1965 chevy truck

Ok, I will take a look at the wires and horn relay. I hope that is where the problem is at. I will keep you guys posted on what I find. Thanks for the help!
