Hello; my charger Giant GLI270 AA 5 pin charger has become wet.
Some resistors are blown.
I cannot read the value:
R14, R16, R15, R12, R13, R11.

Can someone help me?
Thnks in advance.

Hello.
Of course you checked the input and output fuses first... ?

 
Hello.

Yes; I did. Also replaced three mosfets (2x K16A60W) and 6N60.
 
I cannot find a technical diagram so I hope there are other options to find de resistor values??
 
Option C. Buy any 6A lithium ion charger and chop the 5 pin cable and plug off the Giant charger. The CANBUS circuit is only needed for the 60% storage feature (?)

Any 6A charger? I have Bosch 36v 6A lying around and my wife's Liv charger just died. We're traveling with the bikes currently and a replacement charger cannot be sourced before go home.
 
Yes, any 6A DC 42V charger will suffice. Connect big Black negative wire (Pin #0) and Red positive wire (Pin#1) to the respective charger outputs. Thinner yellow, green, red Canbus wires can be cut off and isolated.

Using a generic charger might create problems you don't want to have, especially on Giant batteries.


@bobbyb ....if it's still of interest

If the primary side mosfets were blown, also check/replace the pwm/pfc controller.
