OBC Bypass fail... Need Help.

[hawgsalot]

Ok 2008 Precedent Alltrax XCT 400 Amp..

The steps I took

1 Unplugged 6 wire OBC plug, spliced and connected the blue and white wires on the cart side.

2 cut and spliced the 10 gauge black wires going into the obc. One comes from the charging receptacle one goes to the controller B- but a plug on the controller.

Cart fires up won't move it's like the solenoid doesn't activate, no click. Where did I go wrong?

Did you check this out already?

Did you put the Tow/run switch in Tow and disconnect the battery pack before starting to cut wires?
Checked for any blown fuses? There is usually one in a weatherproof in-line fuse holder near the solenoid.

Yes put in tow before disconnected the negative and positive before I cut any wires? Should I take the 10gauge wire directly to pack instead of B- on Alltrax? I read the OBC bypass thread, doesn't seem anyone has this issue... I also don't have an inline fuse going to solenoid. One side comes off controller positive on side off positive. Then I have two small wires connected to the bottom of the solenoid, I think blue and blue and white one.

Headlights don't work either if that help track the issue.

shameless bump

What is the best way to check if the controller is sending the negative to the solenoid? Is there a way to check in the xct app to see if it's getting and receiving the right signal?

The 10g Black wire doesn’t matter for operation.
That is only negative from the Charge receptacle to B- for charging. As long as it is connected to B- terminal at the controller then that’s fine.

The early IQ carts the fuse may have been near the Tow/ Run switch.Cant remember exactly.
If your lights don’t work then you have a blown fuse or connected the wrong wires together.
Can you post a pic of the white and blue wires you connected?

Hope this shows up if not maybe a direct link works

I looked for a fuse and have nothing at tow/run switch just two red wires coming in. I definitely connected the blue and white wires and I suspect you're right about the 10gauge negative, because the new smart charger worked perfectly. So now I'm down to the blue and white wire connection, maybe somehow I got a bad junction or maybe a seting in the xct, I'm at a lose. What I do know is the solenoid no longer clicks, the reverse buzzer works. This easy job now is a pain in the ***.
