I recently swapped in a brand new out of the box starter from SBT. No Crank. Long story short, I used jumper cables to put 12v directly to the starter and it did the same thing.
Brand new battery (12.8ish), bypassed the relay. It acts like it wants to turn the engine but just wont do it.
I took it far enough to pull the engine and actually turn the engine by hand. With the spark plugs out its pretty tight to turn it until it closes the valves again. Checked timing its good. I ran the starter while it was off the engine, and without a load it seems to function fine.
I checked continuity on the starter (where the red 12v wire connects on the stud) to the outside casing of the starter, particularly where it bolts to the engine...and I certainly have continuity. Forget exactly what it was now, but it was pretty good, within a couple hundred ohm. From my understanding, the entire outside of the starter should be grounded (grounded from the block)and only that stud and the internal components should have 12v right?
I can get continuity from the stud to the engine block with starter installed. I'm assuming this is why its not working. Thoughts?
I did ohm out the old starter (SBT as well) and I could get some ohm from that stud to the outside casing as well, but much much higher so its making me double think.
Are SBT starters generally okay to use or crap? Just bad luck?
