Thanks all for the info thus far. I received the new part and started working on the replacement...

I wonder if mounting the CE-601 I have to the plate without bobbins will cause certain failure? The only reason I'm considering this is because the unit I received has a shorter plug that barely reaches it's connection point without snipping the plastic tie to the chassis. If I snip it, the cable touches the oil filter which makes me worried the nearby heat will cause it to melt. I'm thinking removing the bobbins will give me the slack I need.

I managed to get the old 601 off (with much difficulty! The nuts are so damn close to the rectifier body...), splice a new larger ring terminal for the junction stud, and connected the new ground. She fired up nicely and voltage is now reading normal, so it appears the old rectifier was the issue and the new one is charging the battery. Now just need to figure out my mounting to avoid the plug cable from being pulled tight or touching the oil filter.

I'm not much of a mechanic so I was pleased to get as far as I did!

Anyone else experience this cable length issue? Any insight would be much appreciated.
