help roboteq

[adz600]

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

no relpys ??
anyway started the repair today might as well give it ago,
opened up the roboteq and removed all thermal bridges, back of the board is in a bad way lots of solder furring from the lead free solder and also lots of bad soldering joints from new,

plan is to clean the whole board with alcohol and tooth brush, refloat all solder joints and replace all 4 battery cable inputs with new cable, re secure all capacitors with a hot glue gun and over the new and existing large size cables, this is standard practice on many board as it adds strength. Note bad design very little clearance on main power cables too heat sink, ie less then a rule thickness this would cause short circuit in heavy impact. applying a thin layer of ptfe self adhesive plastic to inner heat sink body to avoid this risk.

wish me look should be done by weekend will include photos then,

All new cables attached and all joints refloated and full board clean, insulation fitted to rear of board heatsink.
Looking to finish and power up test tommorrow, used 10awg wire as 8 won't fit in board they had trimmed it to fit !!!

If it works, you may have a job for life!

some photos off the job and the many problems with the controller, fitted all the thermal bridges and fully secured the board partially tested also lights and control screen work with 12v input yay.

just motor testing left over the weekend fingers crossed for the last test
