Howdy, boys:
This is a 6V adventure.....
When I replaced my SH battery box, I went ahead and installed new original style battery cables at the same time. The cables I previously installed are only a few months old, made of 00 cable and have soldered and crimped ends. They appear to be in really nice shape still. However, the ground cable was much longer than an original ground strap (it was bolted to the frame in a different place), and the tractor would not turn over quickly, nor start well recently. I have been careful to keep all terminals and connections clean. Surely, it was not due to the longer ground cable?!
So, I had the starter checked, replaced the mechanical solenoid, and worked with the connections. I put "star" washers under each connection. Bright metal. No better. New battery. No better.
When I went to the new original type, much shorter, ground strap yesterday, that made all the difference. No more voltage drop. It turns over faster and fires off instantly.
So, the lesson I learned here is: Even if the cables are in good shape with clean terminals and of the correct size - keep them as short as possible in order to minimize resistance and voltage drop - especially the ground strap. It sure cured my 6v SH hard starting problem. Maybe my experience will be of help to you, too.
