Voltage regulator. Notorious as a trouble point after 40 years. The modern replacement is electronic and potted in plastic (tar?), so waterproof. I think (?) that's the same regulator used on YM240 and 70's Datsun.I believe this is the voltage meter? Not positive, however, the location matched your discription. Looks original to me. I bought the tractor and it had been gone through and fixed up.
