Battery not recognized , running slow.

I would really appreciate if someone could share some information. I have a late 2013 retina macbookpro 13inch which had liquid damage. It was revived by a thorough m/b clean out. It worked for a couple of month. Now it has run into problems. Here are the symptoms and my findings-

Symptoms-

1) The computer runs very slow.

2) It suffers quarter fan spins.

3) Keyboard and trackpad no longer works.

4) Charger light turns from green to amber even though there is no battery as I have taken it out.

5) Battery not recognized when plugged in.

What I have tested-

1) Power rails- All come out normal except for the fact that G3H runs at 12.3V and not 12.6v.

2) The Thunderbolt booster circuit does not show any power beyond the source at Q3080. I assumed this could be

normal as no thunderbolt device attached but I could be wrong.

3) Resistor 7110 (Chgr acin) should be 68.1K . However it starts at at 35 and runs to 55K when tested. Its unstable. Put in a new one with same results.

4) Resistor 7102 (Chgr reset) should be 100. I'm getting an unstable reading of around 50. Changed it and still getting the same result.

5) Battery connector J7050-

Readings taken when plugged in-

All ground pins (7-18) go to ground so this is normal.

Power pins 1-12 reads up to 11v but rapidly drops to under .3volts.

SCL pin 13 and 4 reads 3.4volts

SDA pin 5 and 14 reads 1.4 volts

6) Near the SMC, resistor 5380(SDA) and 5381(SCL) both read 3.4volts . There is continuity from R5381(SCL) to the battery connector pin 13 and 4. There is NO continuity from R5380(SDA) to the SDA battery pin 5 and 14.

7) There is normal continuity from the battery connector J7050 to the SDA and SCL pins of D7050 rc/clamp. The clamp gives 3,4 volts for SCL and 1.4 volts for SDA.

Items replaced with no difference in machine operation after change made-

1) Isl 6259

2) Inrush limiter Q7180

3) Q7130 m/fet

4) Q7155 m/fet

5) D7050rc/clamp

Any clues would really be appreciated. I am at a lost and am really hoping its not the SMC. Any suggestions before I go nuclear? Thanks very much for reading this.
