Yes.I've cleaned the area all around U8 and Q17&18 with an electronics cleaner and..., didn't make any difference ...Can U8 be replaced with another LM324DG ? such as this one: @uk.farnell.com...
I presume "licked" ought to be "leaked", correct?dan1976 wrote:... It looks like the battery licked over capacitor C112.
I do not know its capacitance. However, like so many other such capacitors seen on these PCAs I think its function is to absorb some of the local electrical noise to provide a more even, or smoothed signal to the MCU. Its value is probably in the range: 0.001 uF to 0.01 uF.I removed the capacitor expecting it to solve the issue, still the charging error repeated it self.
Few questions:
1. Are you familiar with C112 capacitance number?
No. But, if the fault just happened to be associated with conductive salts--deposited around & under C112--from the leaked battery electrolyte; and if you failed to clean up the board space between C112's two solder pads, then residual salts could impact signal level out of U8. I'm tending to recall that the C112 end of U8 processes "temperature", which is not an err3 threat.2. Do you think the problem is reoccurring because of the missing capacitor?
Have you read enough reference posts to understand how U8 (and its peripheral components) relates to the charging-err3 fault? You should have discovered this viewtopic.php?p=120477#p120477 as you read page one of this thread.is there something else I'm missing? ...
