Just got an 86 D150 auto 318 2 barrel. Drove it for 2 days. got in it yesterday morning, go to start it and nothing happens. it doesnt make any noise. no turning. no starter clicks, nothing. all the lights work, battery IS GOOD. Ive tried taking the brown wire from the starter and jumping it to + bat terminal and the starter will click. plug it back into relay and nothing happens. im not too familiar with dodges so im asking for any help or any info that will help. Thank you

 

I don't know how you tested the battery but batteries can seem fine and not be. Battery dealers will usually test them for you.
Otherwise it sounds like the starter coil went bad.
