Find the 2013-2014 Service Manual. (BRAMMO-EMPULSE_service-manual)
The manual might be helpful under remove controller or whatever it says. Don't try to charge individual modules you will only cause cell imbalance and get error codes. Those error codes you have are related to the BMS. The codes are in you owners manual. You have to charge the whole pack together just like the onboard charger does.
Take off the front plastic cover and disconnect the big blue connector to disable the battery for safety. Take off the bottom cover and you will see the controller but it blocks access to the positive terminal so you have to drop it down. Look at how it is attached and remove any screws that are holding it to the bike. Don't disconnect any wires or cooling hoses. You just need to get it low enough to get the top plastic cover off so you can hook you chargers up. Service Manual 90-5 (Picture 11 With Red arrow)
The battery modules are arranged so the most negative terminal is towards the back of the bike on the upper row, probably the one you charged. (Service Manual 20-1 Battery #1)
The most positive terminal will be on the rearmost module in the lower row. The big blue disconnect just hooks them together. The positive battery cable might connect to a flat metal bar. You should be able to see the positive battery cable going up to the rearmost lower battery module. Plug the blue disconnect together and avoid touching any connection. Check the voltage between the negative terminal under the seat and the battery side of the contactor.
Your charger, plug them in and check them with your volt meter to confirm proper polarity. If you hook them up backwards you will fry the chargers.
Hook the negative of you chargers to the negative pack terminal and the positive to the battery side of the contactor and plug it in. The lights on the chargers should be red to tell you that they are charging. When the voltage gets to 100 try turning on the bike.
