Starter on 94 sidekick strange cranking sound
#9
the starter was bad.
as stated many times.(PM)
power in good, voltage input good, power out weak even with spark plugs out.
bad starter, by pure physics, (engine not seized , starter pinion not seized)
now with photos, what a sad old pathetic starter.

we found that jumper starts fail.
11vdc across starter post to case, cranking. good.
no ammeter to see if the normal 100 amps flows, my guess yes, it does, based on 11vdc above , normal drop. (in battery feed, and cables not dropping at all)
the starter has 11v x 100a = 1000 watts input, that is 1.5 Horse power,
that power, fails to create 1.5HP, so the starter is bad. or is eating that power (turning it to heat)
the start output is weak, for any of 10 reasons. non of which matters, as the SUB parts are not sold on your island.
the starter can have bad bearings and allow the armature to hit field coils, and other odd failures. (all starters end like this)
slipping overruning clutch
bad brush, wrecked commutator (seen above)
bad field coils.
solenoid contactor burned up.
Pinion gear stripped, damaged and binding to fly ring gear.
armature coils open or shorted, or shorted to amerture segments. (growler tests fail)
broken coils to communator segments.
commutator, segments (mica's) not undercut now (yes), allowing brushes to bounce.
and more.
