OK. Reheat the TAHVO IC (N2300) and the RETU IC (N2200). I'll help you a little bit with a picture:

1=tahvo (charge ic)
2=retu (power ic)

check out the shorting ohms between the positive and negative battery connector, check out without on the set, if there would be simple lekage shorting between to polarity it may your pa damage.
