Well if you know nothing I'd say it would hardly be a safe thing to do in
case you reassemble it incorrectly and something is live afterwards.
If you know what you are doing there is little to go wrong. I'd start with
the naff switches they tend to fit to these things. If shorting the switch
makes it burst into life, and assuming you still have your fingers at this
point then the fix is self evident. However I'd suggest at least getting a
meter of the analogue variety that can measure resistance and voltages in ac
and dc as that can be the safest way to troubleshoot dangerous stuff.

My Bosch hedgetrimmer (AHS 55-26) died suddenly the other day.

I've had it, and heavily used it, for just over two years. There was
no major "trauma" (such as dropping it): I just laid it down in the
middle of a job, and when I picked it up again, it was dead.

(having tested the cabling!) I started to take it apart, on the tried
and tested basis of taking something apart, then putting back together
again, will often fix it -- usually as a result of finding "something".

I gave up taking it apart after I'd got the 14 special screws out, to
split the casing .... it looks to be a major disassembly job.

I asked a local gardening tools place: "not worth it mate: we don't fix
'em: by the time I've disassembled it, run tests, possibly got parts,
you're going to be paying more than you bought it for." (£130 btw).

So I'm back to Plan A. Before I embark on this job, any ideas, or
advice such as "don't bother".

I had thought it might be carbon brushes, but (a) getting at them is a
challenge (b) I've never had brushes fail on me in anything for decades.

BTW I am not leccy-literate: replacing whole parts is my limit, and even
diagnosing parts would be beyond me (e.g. using meters to test voltages
etc).

Give it up before I start? Nahhhhh -- couldn't possibly chuck this into
the spares corner without first taking it completely to bits.
