Default Re: Voltage reducer problem

What ogre said.

I think some 97 DS had a run/tow. Either yours does or it does not.

I never understood the drawing above, I'm sure it works but it looks to me like there is only 36 or 48 volt negative.


You have 2 inputs 48v, 2 outputs 12v. You also have "trigger" wire to "start" the reducer when key is switched on. Some say to hook 48v negative input to reducer not from pack negative but from B- at the controller so the OBC can monitor what the reducer is doing and charge the pack accordingly.
