Enertia B7/B40 Error, bad battery

<< < (3/3)

GOZR:
My light on this battery is red

sunchaser:
Here's a section of a Valence (the battery manufacturer) document that explains some of the LED flashes on the batteries.  I'm also including the Brammo System Warning and Error Codes page from the Enertia manual.

It sounds like one or more of your batteries has fault condition.  Having a red LED isn't great, but it's better than no LED activity.  If you have a multimeter, set it to measure DC volts and check the voltage of any batteries that have a red or no LED activity.  Keep in mind that it can take ten seconds or so for the LED to flash in some cases. 

Also be careful not to let the metal part of your positive multimeter lead touch the frame or any other metal parts of the bike during your testing.  You definitely don't want to short anything.
