I hope I'm not parading my stupidity too much with this question. Apologies if I am.
Anyway, I've read in a couple of places on this forum that when reconnecting the battery negative (assuming that the positive hasn't been disconnected) then I should set the ignition swith to position II BEFORE connecting the negative.
Why is this?
I recently replaced the siren on my V70 and didn't do the ignition switch bit when reconnecting the batery. I haven't seen any ill effects so far but maybe I was just lucky.
Cheers !
