windscreen wipers suddenly came on by themselves

[Johnno]

The windscreen wipers on my '81 244 came on by themselves yesterday, and stayed on.

I experienced this once before in a Mitsubishi van years ago, and the problem was a stuffed battery. So I turned the lights to park to reduce current drain (daylight driving lights are then off), and about 15 minutes later, just before I got home, the wipers switched off.


I checked the battery (less than year old Century), and it's holding 12.2 volts, checked with engine running and alternator is charging at 13.4 volts.

To be safe I put the battery on charge for a few hours, but when I turned the ignition key on, the wipers started up again ??

Any suggestions on what's wrong ??
