/takes cap off
Mind you, this board dates from 1995 or 1996. Check the history.
That's it Uwe. Now that we've sorted the esoteric bit, has anyone got a
clue about the BTS425L1?
This board has bts 425, 432, 610, and 620 devices around it in no
discernable pattern, switching lights, indicators. Did anyone ever get
such a stupid idea? the BTS range has all sorts of intelligent fets
(Some even offering condition feedback).
And the little dweebs here try to steal a car by shorting an indicator
bulb, thus hopefully blowing the fuse on the alarm when it goes off.
