No, Pic does not write to EEPROM. ( would it help??).
Why is welding without disconnecting batteries so bad??
Any input here will be appreciated.
Also, there are a few ways to isolate circuit board, (relay, opto isolators, etc...), but if disconnecting batteries is only option, then maybe that's what we will have to do.
Please just explain why this welding procedure of disconnecting batteries is necessary. I have pretty good idea why, we probably were taught this in college, but that was years ago(18yrs to be exact), and I haven't had to think about this.
I know the batteries can explode, but only if hydrogen gas is present.
Help me out, or maybe I will dig out the old engineering book of mine.
Thanks for any help.
