Default OBC Bypassing

I think the White and Blue work better for all years IQ and Excel carts.

For the Regen-2 and other Model Years where the Blue wire was connected to the harness instead of the controller, the OBC provided power directly to the electrical system.
If the White and the Red/White wires going to the OBC are the same gauge, I would still use the White wire, but add a 10 amp inline fuse.

If the Red/White wire is a larger gauge, then use the Red/White on the OBC side of the connector and keep the fuse.

I like the idea of not having any power going to the Controller connector when the Tow/Run is on Tow (which is how the OBC works).

Using the Red wire would also provide non-fused 48v power at the controller connector.


The above information is for Sepex only systems.


All model years of the Series carts, the OBC provided the negative side of the Solenoid on the Yellow wire.

For the Series carts You just have to disconnect the Yellow wire from the OBC and run it directly from Solenoid to controller B- (or other negative source like pack negative).
