If you have multimeter read voltage on 5th and 6th pin of the M92 chip. should be 3-5v charger plugged in.
Check caps near BQ on shorts without a battery connected.
I had 0amps on charge when BQ is completely dead, usually it burns a fuse also.
Check battery voltage when it's plugged in to the switch and it's works, check voltage on battery unplugged, it might be a controller inside of the battery itself, try other one of u have it.
There are resistors right on top of the BQ those are might be faulty also, check if u can read resistance across all of them. Be aware that in circuit they might have different readings +-.

Hey I just checked the voltage on my board if I bridge those two pins does it fry the chip, I had my multimeter set to voltage in the up 20 range and I placed one probe end on the capacitor and to it's corresponding pin on the m92t36 chip, so what occured was I was getting no reading on capacitor on pin 5 to pin 5, and capacitor pin 6 to pin 6... I didn't know what I was doing so I started tapping other pins and a lot of them said 3.3v... anyways I'm guessing I bridged pin 5 and 6 with the probes because now it doesn't charge at all...

Though, one big thing I want to know is if no voltage reading was coming from the capacitors to their correpsonding pins does that mean that the M92T36 chip was faulty?
When checking for voltages when the system is running you should place black probe on ground and red probe on the pin or cap or whatever your testing, in effect you were testing for continuity which is normaly done with the systems of and the battery disconnected.
I'd say the chip was probably ok but you've possibly just caused a short.

Voltage in those pins aren't coming from caps it's going to caps, if you didn't had readings on one of them mostly one of the power rails was in short. Checks caps around. if they are shorted to ground.
