Moving forward, my next project will be researching why my carts top speed is so slow? From a stand still my carts starts out with tons of torque, but quickly slows. Also when in reverse it barley moves. Trying to do my part as I did purchase my new charger from a site sponsor.

Tom,

Bypassing that OBC is just a temporary setting to test if your OBC was bad. Obviously your was. You need to replace the OBC or best is to buy and use a smart charger from now on like a Lester Summit II. If you are using your Powerdrive charger right now it is only in manual and has no charging controls at all.

2nd, your speed sensor has failed and your cart is in "Limp" mode. That is why it takes off hard and then slows down. Reverse is only 50% to begin with so now you have less than half of that..... (You can verify what I am saying by manually pushing the cart forwards and backwards, where you should be feeling a lot of resistance and also loud beeping. If you are not getting both, that proves the speed sensor has failed.) You can get an OEM replacement speed sensor here https://www.revolutiongolfcars.com/motors just identify if yours is the top-hat style or Flat snap in style. They are easily seen by looking up under the cart and the back side of the motor. That is where they connect into it at.

Cool and thank you for the information. I did purchased a smart charger to replace my power drive. Thanks for watching out for me.

Wow.
I have just spent the last hour going from page 1 to page 21 of this thread.
Great read. I am getting ready to do my own bypass of the OBC, cause
like everyone else's mine has gone bad.
After reading all this, I was just wondering, instead of spending hundreds on a DPI charger, why not continue using the same one? People keep saying that you have to keep an eye on it if you do because it becomes 'manual'...what about one of those outlet timers that you can set for variable hours and then shut off automatically?
Would this work? I haven't seen this mentioned, so thought I'd throw this out there. Am I missing something?

something like this one:

something like this one:
Without the OBC, the regular Club Car charger will not have the "smarts" to properly monitor and charge your pack. In a pinch and very short term it can be used but you will need to monitor the pack voltage and stop the charger when your pack reaches 60 volts, a timer doesn't monitor pack voltage so it would serve no purpose. Again, this is a very short term solution, you need a smart charger like a DPI or Lester or Yewy. Smart chargers have the ability to run battery specific charge "routines" that will keep your flooded batteries in top shape for many years.

Gazoo is 100% correct. You will be ruining your pack as you have no algorithm to control it. You would basically just be surface charging the plates.

Well, crap on a cracker.
How about rebuilding the OBC?
What are the chances of success?
Do any of you know reputable rebuilders and possible cost?

Not possible, not only it is a complex device, but it is also "potted" which makes it difficult to replace components.
