EPIC Lithium Converstion

[danbury]

I have Lithium Conversion experience with almost every brand of golf cart but this one has me stuck. (It's a 2020 E40.) After installing the Lithium battery the golf cart won't go. This issue is typically caused by a Charger Lockout. But I can't find it so that I can override/bypass. Need help.

On other Icon models people either programmed the charger not to "lock out" cart moving (believe line 5) or made a Jumper:

"...The trick to removing the factory charger is a two wire cable from the charger that supplies on/off logic to the motor controller so that you can’t drive off with the charge plugged in. A jumper across that connector fools the controller into thinking that the charger is disconnected and the cart will run..."

I found a red wire coming from the multi-pin connector on the controller that wasn't connected. SO I connected it to the B+ on the controller. Now it runs.

Out of curiosity, and so others can be helped, please elaborate. Did you disconnect this wire when puling old battery, was it a loose wire in connector, and if so, why did you need to reroute it? Did you have to make the other changes people did (reprogram, jumper) pulling factory charger....

Thanks.

If you do experience charger lockout, you will need a jumper on the 2 wire plug seen in the picture (solid orange wire and yellow wire w/green stripe) This is coming from the cart harness and plugs into the factory charger(red and black wire)
