what should i check. Help please
12.3 is too low and the SMC is not talking to the ISL6259. Disconnect the battery indicator cable to rule that out as a problem. See if PPBUS comes up to 12.6V now. If not do a diode mode reading on both data lines going to the battery.
i measure board outside case on table so only magsafe is connected. so from what point should i measure to with point . i take it red probe will need to be on ground?
