Hi Rob,
Here is the original issue:
I changed the starter motor originally as the engine is off an old 1972 Air portable, which was reconditioned in 1986. When the engine failed to turn over, I took the starter off, stripped it and the bushes were near the end of their life, so given the age, I bought a new starter. When I put the new starter on, I had the same problem, until I removed the plugs. The engine then turned over (hence the hydrostatic lock solution). With the plugs back in, the engine started and no issues until now.
So with the pos and neg cable renewed to the starter, I attach jump leads directly to the starter and bypass the electrics, neg attached at bell housing and not attached to the chassis. The motor initially engages, wit h a clunk and then nothing, if I then re apply the pos lead, it will turn over very slowly and then stop. The cable then gets hot and I am none the wiser. I was working on it this afternoon but no further forward.
