Maybe someone owns a CCS can take it apart and find out what's the cause for the failure from design point of view? Funny N.

If the vulnerability is particular the the CCS units, then "something else" would seem to be the answer. I have abused my ICD2's in most of the ways you described (miswired cables, power applied at inappropriate times, etc., though no high voltage arcs), and I've never had one go bad. I've had more trouble with the PM-3 (which is not under my care). But the fact that Microchip will repair or replace these devices (no time limit that I know of) suggests that they put some thought about these problems into their design. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
