1992 Chevy Silverado K1500 No Power!
first buy a DMM meter ,spend $15 and end working blind.
the battery and alternator are easy to test and for sure loss of any kind of DC power easy to find using the meter (ASK HOW)
K2500 pickup or Suburban???? no told and wiring not the same.
no engine told and that too sets wiring. OMG 6 engines 2 diesel.
elaborate NO POWER< means head lamps dead? what?
and stayed on? means what.?
STEP #1 alternator work , battery NEG LUG OFF FIRST or you will blow the 100amp main fuse. doing this ALL WRONG and if a fuseable link, can be hard to find, as others say, not me.
never ever connect any main battery backwards
or you will blow up very expensive electronics,
best I can tell is first failure was the fuse even those kinda hidden
fuses called Fuseable links.
fuses are first on cars, of head lamps dead and park lamps dead
this is first, head lamps work keyon , or off.
so is first thing to check with DC POwer loss, (NO POWER"?)
if battery is 12vdc then the power is not lost but fuses are blown
for sure. head lamps are a safety devices that work even no key in hand.
the under hood box has a fuse marked Lighting, if blow HL are dead
just below Lighting fuse is battery bus bar fuse. <<< blown?
the only hard thing THIS CAR,is the online books stink
back in 1992 no digital books then so most cars nobody was willing th scan 500page service manuals. (nor me)
so only sparse information exists. (join k2500 real forums? Chevy)\
this truck does have (did new) 4 x fuseable links, 1 for alternator
but only that blown kills alternator and runnining engine battery is not
13. to 15vdc so the battery goes dead fast 1/2hour fast.
below 13vdc the alternator is dead or fuse link ALT is blown
there are more LINKs to blow 3 more.
others kill the cab or engine bay fuse boxes dead
so all boxes must be check for lost of 12vdc raw DC power.
head lamps
parking lamps.
to top the list and more, check all things DC power, even radiol
the list of things dead tells you what fuse box is dead.
hope that helps in any way.
regards.
