I started the restoration of my ES 730D several years ago and am just now getting it finished. I've gone through just about every piece of it. I installed the Agri-Services wiring harness and overhauled the generator several years ago and bought the regulator at the same time. Now, several years later, I can't seem to get it to charge.
I'm confident that I've got it wired correctly. I've done several of these. The generator should be correct, but since I did it years ago, I just don't know for sure. I bought the four terminal regulator new.
When checking voltage across the A1 and A2 terminals, expecting 28 volts, I get nothing. The red dash light also remains on. Pretty sure it's not charging. I did polarize the generator before I started the tractor - between BAT and GEN/ARM. It sparked as expected but when I checked a second time, there was nothing.
Any suggestions? Start with the regulator then the generator? What are some good diagnostic tests without having to start swapping out parts?
I'm an electrical engineer, so I think I have a fair idea how the 24 volt system works. I didn't have any trouble when I did the same thing to my 24 volt 830 a few years ago.
Thanks for any advice,
