Anyone know if a 1966 A/C HD16DP charging generator... even used... can be had? The one on mine has never worked since I have had it and I am just getting around to addressing it. Also... if the specs... i.e. output current and voltage is known that would be greatly appreciated. I know the system is 24 volts but I have to believe the generator output is a bit higher than that. I know there is a regulator involved as well.

I converted a couple of Caterpillar bulldozers to the bigger Delco 24V alternators, it was a fairly easy switch, also eliminating the need for an external regulator. If I were you I would do the same on the HD16.
Currently- WD,WC,3WF's,2 D14's B. Previously- I 600,TL745,200,FL9,FR12,H3,816 LBH. Earth has no sorrow that Heaven cannot heal!

Eric is 100% right... Get rid of the generator and regulator problems and go with an alternator with internal regulator...

capacity wise, most of the generators in that era were 30 amps MAX... Unless you have a bunch of headlights on the tractor, 30 is fine... If you go with an alternator it might be 30 -35 or 60 amps... all are OK.

Something like this... you have to figure out the mount and pulley / adjustment is the biggest deal..... Make sure the SPEC says "IR"  Internal Regulator... Some dont..
