So that wire can be removed as the obc is no longer needed correct?

Upgrading to Lithium batteries and will wire the new charger directly to the pack, do I still need to bypass my failed OBC?

It's a 95 DS Series cart, and I just want to make sure the failed OBC will not cause any performance issues.

You need the Yellow wire at the OBC that runs to the small post of the MC to be cut and then cut the Black 10g wire at the OBC that runs to B- at the controller. Butt connect them together and that will supply you the Negative needed for the Main Contactor's (solenoid) activation circuit.

anpgator, Nole is the master of this procedure and knows what he speaks of.

To avoid confusion as many have made a mistake doing this, look at the last wiring diagram in the "stickies." (as of 10/2019)

Make sure you do not confuse the Large and Small yellow wires. Also, do not run the wire from the OBC to B-. You will run (connect) the wire from the small SOLENOID post to B-.

Newbie here. Read the note about starting new threads but the post from NoleFan4Ever on 05-20-19 a few posts back is where I am with this. So if a new thread is in order I will pursue that. I have read all 27 pages btw.

Picked up a 1998 Club Car DS (Series I think, no run/tow), new batteries, 5 cables, lift kit, repair items etc, plugged in the old Power-Drive charger and nothing. Relay getting pack voltage but not closing. Needs a new relay, no problem. Bypassed relay under close supervision and watched the output signal from the OBC to the relay in the charger, charger works great but the OBC not stopping charger. Watched amp meter and used good DC voltmeter etc. Boiling the crap out of them but still getting full voltage to the relay coil. So I determined the OBC was bad and not shutting off the charger when it should. Ordered a new Lester Summit 11. In the meantime have been driving it around this week and recharging it manually by watching the DC volts. Runs great. Received new charger and mounted on-board. Thinking I knew everything, I completely removed the OBC and have performed all of the wiring changes I have read about. Main cables back on, solenoid seems fine. Plugged charger in and appeared to work fine, however the resistor on the main solenoid lugs started getting very hot after 30 minutes. Immediately disconnected. Something is wrong.

With black wires connected to pack and red (+) disconnected, when I touch the red charger wire from the output of the charger to the battery post it arcs a little. The charger does not have 120 volts to the primary side (not plugged in). Is this because it is "Charging" the secondary side of the charger transformer? Like a capacitor if you will. There may not be a transformer per se', at only 8 lbs it could be mostly heat sink I suppose. I don't have a DC ammeter but could use 1 amp, 3 amp, etc fuses to determine the "arcing" amps. Have left it disconnected for now.

I have another issue with voltage on both sides of the solenoid but will wait to see what replies I get before going on. I may not be handling this correctly. Maybe needs to be in the solenoid diodes arena. Or a new thread.

Thanks.

Wenona this is a "sticky" thread dedicated to OBC removal. While you have some issues that may be OBC related I would start another thread in the Electric Club Car section.

It may take several pages to iron out what you have going on.

Thank you. Will do.

Being a newbie, can you give me insight to "sticky" versus thread?

Just go to: "Home" then "Electric Club Car" then " New Thread."

Post your question with as much detail as you can and someone will help you.
