Having read the manual for the MCR2 I feel confident to set one up. I'd put money on it that the one I took out of the box, if re-installed will work if set up properly, provided the field coil series resistor is ok. The manual doesn't say what the resistance value is. Does anyone know?
The problem I'm having with the electronic regulator is that it doesn't seem to be switching on and therefore no current is passing through the field coil.
I am interested to see that Peter also had problems with a Wassel.
It is interesting to note that the Wassel requires that the field coil polarity be reversed and connected to the dynamo output terminal 'D'. The field coil is then pulled to ground, via the 'F' terminal, to get current to flow through it from the dynamo. Because the regulator is electronic there will be some sort of device (power transistor) that will first need switching on, so, maybe my dynamo just isn't outputting enough voltage without a field coil in circuit to ever activate it / switch it on? Sadly, there doesn't seem to be any technical support / help desk for these devices.
I'm pretty certain that my dynamo is ok though. It easily powers a 21 Watt 12 Volt bulb at low revs!!
The electronic regulator should, in theory, give as good if not better results as a mechanical device, and is essential if you want to run 12 volt electrics (which I want to do with my NH project). I also parted with £30 odd so I'm reluctant to just throw the Wassel in the bin without a fight!
