Yes,you would do better to use the standard Delco alternator on your JD. No need for Bob's diode if you connect the #1 alternator wire to the stock "gen light" wire in the original generator wiring.
By wiring the #1 alternator exciter terminal to the stock gen light,you not only have a working charge indicator in the dash,but the gen light serves as a resistor to limit return flow from the alternator back into the wiring harness. This eliminates the need for the diode.

In most cases,the "one wire" alternator will work the same as a stock "3wire" alternator,so no need to replace the alternator or regulator if it is in good working order.The last box of "1 wire" regulators I bought had instructions saying that if you wanted the alternator to excite at lower rpm,or wanted a gen indicator light,to hook it to the #1 terminal which normally has nothing connected to it on a "1 wire" alternator. just buy an alternator regulator plug replacement kit from an auto parts store for about $2 and connect the #1 wire to the JD gen light wire in the stock harness. It is your option to also connect the #2 regulator wire as shown in Bob's post,the "1 wire" regulator does not need it,but If you ever replace that special "1 wire" regulator with a stock one,then the #2 wire needs to be in place. The only difference between a stock 10SI Delco and a "1 wire" conversion alternator,is the regulator.

The "1 wire" alternators have their place where the exciter wiring would be a problem to install,and a volt or amp guage is in place to indicate charge.
One tip that helps on a "1 wire" alternator conversion where it does not turn the alternator fast enough for an easy light off,is to use as small an amp output alternator as will carry the electrical load. A "1 wire" alternator with the 27 amp stator installed will excite at aprox 1/2 the rpm of a 61 or 72 amp stator/alternator.
