Just unwrapped 1964 chevy c10 w/350 olds. Battery charged. Lights and horn operate.  Radio dead along with starter. Gauge for battery in cab response to key turn?

you should have power to the RED wire..

in key ON.. power to the black and pink striped wire on IGN1..

in KEY on.. Power to the ACC brown wire..


only while the key is in the CRANKING position do you have power to the SOL or purple wire..

oh... the Radio should be powered from the ACC circuit off the brown wire...

the starter should get voltage when the key is in the CRANKing position on the Purple wire.. that .. depending if you have an automatic or a manual transmission will stop at a neutral safety switch with an automatic transmisision..


the Black and PINK wire.. runs the ignition and several other circuits..

I Did not make any changes. Updated the volt meter only. Truck had no issues before covering up for the winter. Actually started a few weeks ago to get things moving.

do you need a wiring diagram???

do you have pictures so i can look around..


start by checking or cleaning the battery cables..  cleaning is a good idea..


80S Chevy Truck Battery Cables

do you see where all the red wires are attached to the distribution stud.. there is one over near or behind the battery that needs cleaning and reassembling..

there is a small wire off the Negative battery post that goes over to the radiator core support.. that needs cleaning also..

take a bunch of pictures of the various connections around the engine compartment and under the dash... i will examine them and see if i can point out an area that needs attention..

i am hoping that you understand that your truck is 50 years old..  and there is a fairly good chance that it needs some cleaning on the various connections..


why not also start with the first half of this test..

All is in order electrically. Clean and tight. Is it possible the ingnition switch suddenly faulted. It does move the voltage meter when swithed to start position.  Reads 12+ volts on meter when key is turned.
