Re: voltage Reducer Ground
Quote:
If you connect anything (such as the reducer) straight to the negative of the battery pack the OBC never knows about the energy that it is taking out of the batteries so when it is controlling the charger it does not put that energy back. Therefore the batteries are undercharged but the OBC thinks that they have a full charge. Because the accessories running from the reducer do not pull a great deal of power (unless you are running an amplifier or something like that) many people ignore it and connect straight to the batteries anyway. This is not really a good practice because the undercharging is cumulative and will eventually reduce the life of the pack. Given that the batteries in the pack are expensive, I believe that it is best to do whatever you can to ensure the batteries last as long as they can. This includes good maintenance and connecting the reducer to B- rather than just to the pack negative. By-the-way, the Precedent (& maybe the DS, I don't know) has a black cable with a yellow bullet connector lying behind the batteries. This is connected to the B- terminal of the controller and is there specifically so that you can connect extras like the reducer. |

I ask because I have a 2004 DS that does not seem to have the black wire with yellow bullet connector that you mentioned. Sent from my SM-G973U using Tapatalk |

Re: voltage Reducer Ground
My comments applied only to carts with a working OBC.
If you have a smart charger (either a later cart with and ERIC or other smart charger, or you have bypassed the OBC and now use a smart charger) then those comments do not apply. As the others have said, in that case you can just connect to the pack. |

Re: voltage Reducer Ground
I have the same issue as Kolassus with my 2015 rxv (navitas controller and allied 90ah pack) I'm waiting to hear back from navitas but what ever happened (I'm thinking the stock solenoid should have been upgraded but was told not needed) gave me the same thing. No click from solenoid and none of my accessories work. I also seem to have lost my voltage reducer but unclear yet if it's related. I'll reply back but were you able to get back up and running and if so, what did you have to do.
