Well thanks guys. ?I wasn't expecting such a comprehensive answer and I am mightily grateful. I am going to used your suggestions and even do a solder job, which will test my skills as my soldering is about as good as my welding, functional but definitely not pretty.
Avo Mk 8, yes the Toro had two 9v pp3's in parallel. It actuates a solenoid to turn on the watering system so it is a very short burst and one battery is sufficient to operate it under test conditions, so I think the two batteries are purely for longevity of operation. You are right that the mains adaptor is my own addition after the battery wires sheared off right where they entered the controller. A bit of butchery to the case has left me with two useable stumps of wires to which I have soldered extentions. We are away from the property for long periods and that is why I decided to use the mains adaptor route. It was only after fitting the adaptor I realised a power cut would reset the clock and timings, as the battery model Toro, unlike the mains version , does not have a decent back up battery, just one that lasts long enough to change the batteries, if you are quick!
I will come back to report progress, but it may be a while as I am currently in Portugal and not sure where to purchase the diodes locally. (Brexit it has put paid to Amazon or eBay, but that is another story that could run and run under discussion).
Thanks again for increasing my knowledge of electronics.
Superb help from Avo Mk8 and DPG makes this forum the best around!
