444 generator wiring

2 old for this · 03-03-2022, 09:05 PM

Customer supplied a non bosch voltage regulator so I don’t have a diagram on how it is wired. Any ideas?

Is this for a 6V generator?

Can you post pictures of the connections and markings on the regulator?

Generator was upgraded to 12 volt. ? I don’t know how.Thanks for your help. Regulator info tomorrow. Any luck on the wiper pivot bushings?

FYI: Greenbook TP10867-1_1974_140_section_3_electrical.pdf (ozvolvo.org/archive/) has wiring info for several different alternator and external regulator combos. Maybe one of them is close enough to your setup.

Regulator is a Niehoff. Left terminal is ARM center is FLD right is BAT. There is also a large black wire with a eyelet. It looks like it could connect to the ignition switch. Thanks for the help.

I'm not familiar with Niehoff regulators for a generator, but I'd guess the connections should be:
ARM (armature) to generator D+ bolt
FLD (field) to generator DF bolt
BAT (battery) to battery +12v post directly (not through ignition switch)
Black wire to regulator mounting bolt to chassis ground (clean the paint off and/or clean the bolt head)

I don't know where the dashboard generator light connects.
