Have a 6, 12, and 24 volt charger

[gmjunky87]

I have an m1008, the batteries were dead, how can I use the 24 volt setting on my charger to charge the batteries rather than unhook everything and do 12v?

To charge with charger on 24 volts Positive charger cable to positive post on rear battery, negitive charger cable to front battery negitive post. If only one battery needs to be charged with charger on 12 volt mode connect positive cable direct to positive post and negitive cable to negitive post no need to disconnect battery cables just remove BOTH crarger cables off one battery before connecting to the other one Gary
