While testing things I noticed my battery voltage was very high (I'd
just been running the engine). With the engine running the charging
voltage is about 19v. A new, probably more serious, problem. It's a
bit of a coincidence, so I'm wondering if they are linked. Could the
high battery voltage have caused the motor to fail? I'm familiar with
low or no voltage from the alternator, but I don't know what can cause a
high voltage.
Assuming your DVM hasn't failed - it is reading some 12.5v from the
battery with the engine stopped? - the alternator regulator has failed.
This is usually internal to the alternator but can be replaced for about
£30 if you can be bothered finding one.
Unless the rear wiper was in use for a long period, it's unlikely this
high voltage will have caused it to fail.
