Try left side, up behind instrument panel, in a difficult to get to spot.
I saw that gear solenoid up high on the left! I spend a bit of time behind the panel tonight. I still cannot find the regulator. I went through the engine side, and used an inspection camera for the hard to see spots behind the panel. No luck! I will have to follow the field wire, but there a lot of similar wires! Any other suggestions? There is no regulator in the alternator.
