The only time I have come across damaged electronics after a jump start is on two separate occasions when the owner of the vehicle with the faulty battery has tried to swap the faulty cranking battery with a replacement battery, while the motor was still running.

I have no idea why they did what they did but in both cases, they stuffed their alternators.

Thanks for the follow up

Clears up my main concerns & I'm happy to carry on jump starting as required
