hi all im 18 and i live in north carolina. i have a 1980 c-30 4door long bed dually and its called the pig. we call it the pig cause when me and my dad went to look at how the truck looked we bought it and he drop it home. the truck had a radiator leak and we call it the pig cause it sucked water down like a pig does and also it sucks down cas now when i drive it with 9mpg. also my trucks not stock we bought it with a 366 big block in it which then blew and we put a 1987 366 out of a c-70 24ft box truck. the truck runs great heres some pics.

thanks guys i have a question ive got some wiring issue with the headlight switch its getting power but its only sending power out to the headlights not parking lights what could be causing this cause i just replaced the headlight switch. the power is coming straight from the battery with a fuse at the battery and i got my tester to see and i turn it on and then no power us coming out but a yellow wire i have images if you guys dont know what im talking about

check the fuses parkin lights are seperate from from headlights
headlights have a breaker built in

[bigchevyc30]

where would the fuse be at ive checked the fuses on the fuse block adn they are all good

[motornut]

if it's ok,maybe switch with another to check it
make sure it's all the way in too the headlight switch
use a meter to check for power at the switch
i would disconnect the plug under the hood that has the parking wires in it
it will seperate to three plugs one of which will lead to the lights
with it out look for the brown wire,this should be the power to the lights
i would ohms the wire to ground to check for shorts
then a test jumper wire to see if they light up
if ok then hook it all up and you can rule out the exterior

[bigchevyc30]

i already know there is no power coming from the switch for some reason as i can put my test light up to the yellow wire which is the only one beside my power wire going in the switch. would i just be able to unhook the brown wire and hook it to power to see if they work or would i have to try something else

[motornut]

With the switch out , there would be no fuse if using the red to jumper/ test,if you used a fuse with a bit of wire it would be better
