Verify through Phoenix that BSI =
~75kOhm (BL-5C) and BTEMP =
~47kOhm @ room temperature
(~25C)
|
No
|
Check:
BSI: Battery (BL-5C), C100, R203,
pwb and R206
BTEMP: R100, C101, R202, pwb
and R207

|
Measure voltage on R200 towards
D200. Should be the same as
Vbat voltage
|
No

Measure Vchar voltage on V101.
Is it > 3,0V?
|
No
