I've been trouble shooting this problem for a while now.
The engine is slow to crank at first and then builds up to a some-what normal speed.
I cleaned all connections (that I can find) and applied dielectric grease. Replaced both solenoids (corroded), still slow to crank at first.
I bypassed all and hooked up the starter up directly to the battery with jumper cables. Still a slow first crank.
I removed the starter (not fun), cleaned and inspected the armature and brushes, connections and tried it again, same slow first crank.
I took the starter to two different auto stores and had them test it. All the numbers checked out good, all within the nominal range for a 2007, chev 4.3 engine. That's the only info they had to go with for testing.
Both batteries are four-month-old Interstate batteries, 600 cca deep cycle and both are on a tender and fully charged.
I should mention, once the engine is running it sounds good, nothing unusual and warms up as it should.
I'm at a loss at what to check next.
