hi all just redoing all of ceros wiring and the cables are heavily greened and very brittle was trying to get the cables secured and safe when the negative cable soldering on to the board failed, ********** enter as many swear words as possible into there as I prob said them all gutted. I was being gentle after seeing cable.

heres the problem opened it up and to get the back of the board you have to break all the thermal joints and many other solder points ( poor design) managed to reach and get a very weak solder joint but nothing more then that,

internal capacitors are all broken loose also as the soft compound holding them firm has also degraded

is any one here competent enough to brake the board out and solder on all new 8awg hobbyking cable
??????????????????????????????

or ian watts ??????????

please help
