89 ignition problems

[buffblazer]

friend has an 89 chevy c2500 ext cab.

one day it just wouldnt start. not even turn over, so i assumed starter. tested power to the solnoid , good, bat power to the other side of the solnoid also good.


pulled the starter and benched tested it. worked fine. so i re tested the ignition wire to the solnoid, no power re installed starter, got it to crank, but battery was dead so i hooked my blazer up to it to charge. try to re start it, no power to the solnoid. trace it up to the back of the motor and i got intermitt power,

ran out of light so im coming to you guys. what would cause a truck to just lose power to the ignition side of the solnoid but be intermitten?

those have an ignition switch correct? could it be going bad? or am i looking at tracing a bad connection?

So, your getting power down the ignition wire from the switch?

yes and no, its intermitting. i havent tested it at the ignition yet ran out of light

the ignition wire would have power off and on, so im assuming i should check the ignition switch but where is it on these trucks?
