How to properly eliminate and remove an OBC???

[hsfowler]

I assume it is, and I think when [mention]TahoeDawgZ71 [/mention] wrote that it was with the intent of leaving the charger port intact. My plan was to remove both the OBC and the charging port completely from the cart, and I’m trying to make sure I don’t cut the wrong wires

The gray wire with the 3/8 fuse is not needed when using a smart charger..It's purpose is to supply the negative signal from the obc to the relay in the Powerdrive charger..Smart chargers don't need it..You can cut it out completly..

Do you know what the two larger gauge black wires are, and can I remove both of them completely if I am taking out the OBC and original charger port?

Yes you can remove them since you have a summit 2 on board hooked up...

Next question, if I remove the OBC, depin the connector and tie the blue and white wire together, where does the blue wire for the interlock coming off the charger go? Can it go to the same connection as the blue to white wire? [mention]Sergio [/mention] [mention]TahoeDawgZ71 [/mention]

Look at this thread and scroll down to Sergio's posts...He has a diagram on how to do it...

Cool, I can retask it to the power line for a Battery Capacity/Voltmeter display.

Also, from the wiring diagrams, the Brown - Brown/White to the OBC is used for the dash Battery Warning Light.
So the light/wiring can be removed when the OBC is removed?

7 - Dis-assemble the 6-pin connector that you removed from the OBC and de-pin it, leaving only the white wire and the blue wire in the connector. Put retaining clip and rubber gasket back on the plug
8 - Using a butt-connector or a solder joint, connect the white wire and the blue wire together.

I'm going to do this soon on our DS, this is great!
Am I understanding the circuit diagram right?

1. White is a +48v input to the OBC and is controlled by the Tow/Run switch.
Blue goes to the Controller telling the Controller when the charger is charging/not charging?
Is this so the controller will prevent the motor from running when charging? Blue: +48v = not charging, 0v = charging ?

2. There is a Gray +48v wire on the circuit diagram that goes to the Controller from the same tap where the White gets power.
Does the Controller use this input to prevent the motor from running when Tow is selected?

[Sergio]

The Controller lockout description You have is correct for the OEM Curtis controller.

The Gray wire after the Tow/Run switch provides the +48v power the Controller uses for Dynamic brake (roll away brake).

When the cart is on Tow that power is not available and therefore the Controller will not prevent the cart from rolling when pushed or towed.
