Hey all.. I’ve read lots of posts and realize I need the fuse panel layout specific to my 81 K10. I’ve used similar layouts from close years but it seems there’s something unique about the 81’s. Does anyone have a fuse panel layout for an 81 k10 manual trans?

My symptoms are intermittent crank no start then poof! She starts like she was ready all along. The other issue is a continuous battery drain in the off position. I have to keep a battery charger on her if she sits idle for more than 36 hours.

Thanks for any help offered!

I would look somewhere besides the fuse gang for your issue. If you have intermittent starting issues I'd address the ignition starter switch (column mounted) first. This may alleviate your starting & parasitic draw issues in one repair.
There are a few methods to check for the parasitic draw & someone besides me will post 32 pages of procedure for you to follow.
You can "easily" unbolt the ignition starter switch & use a small screwdriver to actuator the starter where the actuator rod attaches. Try this first & see if you have any hesitation our paused starts.

Next you could look for neutral safety switch issues...

Crank no starts aren't caused by fuse box,neutral safety switch,and very very rarely by ignition switch. When you say crank no start, you do mean the starter motor cranks the engine over ,whir,whir,whir,whir but the engine doesn't start correct.
