86' Chevy K-10 shorting out somewhere?

maddog · 02-21-2008, 05:12 PM

i have a 86 chevy K10. full size 4X4. it has i think a 1978? 350ci. i dont know the year for sure, never tryed to match up the vin. anyway the problem that im having is that sometimes the engine won't turn over at all. when a person turns the key to just behind start, everything turns on: dash lights, radio...etc. but when you turn the key to start the starter will click once and then i will loose all power untill i turn the key off and turn it on again. i think that a positive wire is grounding somewhere on the frame? but, i have checked/replaced all positive wiring in the engine compartment that i could find. i am wondering if anybody can help me with this? bad starter solenoid maybe? ...

check your grounds,(body to engine,engine to frame,ect)most part stores can check your starter,could be a bad start switch.rewiring should be you last resort unless your harness is already butchered.a multimeter and some patience,you can fix your problem

86 k-10 electrical HELP
Have you checked starter ?
Seems like your kinda stuck on this idea of a positive wire grounding out.
This is seriously not likely since you are not having fuse or fusible link problems.
Changing/redoing the positive wires may be helpful but that's only one side of the circuit.
I'd not bet against the solenoid entirely, but I think you'll find your whine is from the starter.
