brake lights don't work with AUX battery???
I finished up the auxiliary battery installation today. The lights and turn signals work fine but the brake lights don't. I can't figure it out. The only thing that I'm questioning is in the directions for the brake lights it says, "Turn the key switch on to test brake lights" Everything worked fine yesterday when I was using 2 of the batteries in the pack but now with the aux battery everything works except the brake lights. Hey Sergio, please chime in!

Re: brake lights don't work with AUX battery???
Did you connect the aux battery negative to pack negative and the aux battery positive to the OLD +16v wire from the battery pack?
if not, the +12v for the brake switch comes from the relay behind the dash on a Precedent, so You need to run your +12v from the aux battery to that relay. |

Re: brake lights don't work with AUX battery???
I disconnected the blue wire that was originally connected to batt 2 in the pack and connected it to the positive aux battery post. I then disconnected the negative black wire from the pack negative and connected it to the aux. battery negative. So I need to tie the auxiliary battery negative to the pack negative??

Re: brake lights don't work with AUX battery???
Most likely Yes.
The precedent bucket harness gets its negative from Controller B-, not pack negative, so I am not sure where that negative wire you have on pack negative is going. If +12v positive on the brake timer does not reference the aux battery negative, it will not work. |

Re: brake lights don't work with AUX battery???
I used the negative from the controller. (see Pic black wire with yellow terminal). That is where the light kit was grounded. So....All I need to do is run a ground from there to my aux battery and that is all?

Re: brake lights don't work with AUX battery???
If You connected the negative from the aux battery to the wire that used to be connected to that bullet connector, it should have worked.
If there is a chance that you have used more than one negative source for the cart wiring, connecting the two negatives will fix any issues. Just run a wire from your aux battery negative to that bullet connector that goes to B-. The main reason not to do that is if you have an specific requirement for isolated 12v power. |

Sergio, When I connected the grounds it went right to work. I just want to say how much I appreciate your help. Every time I've had a question you have always been there with an answer. Thanks very much.

Re: brake lights don't work with AUX battery???
Looks good, it is pretty visible
As far as your picture, always take pictures with the volume button pointing down and it will work everywhere. If You hold the phone in any other orientation, any part of the transfer, resize and display process for the image has to know how to read the orientation angle embedded into the image. If any part fails, the picture shows up on the "native" orientation, sames as volume button down view. |
