I've got a boat, a very nice boat that I want to put in order. In this boat there is a generator. It is a Lister BS 649 and the generator is a Crompton and Parkinson 3 phase 7,5 (or maybe 6) kVA.
The generator runs at about 1000 rpm when it should be 1500. I do, however, have 230V and when I increase the rpm, the voltage rises. I opened the generator and found a broken resistor together wit som rectifier bridges, could that be the regulator? I will try to upload images of these items.
The boat is very well documented, but I only have wiring diagram of the 12V circuit, the rest is gone. The boat was built in -59 and maybe this have been in the boat from the beginning.
Questions:
How many ohms and watts is this resistor?
Is the resistor a part of the regulator?
Does wiring diagrams exist?
Is BS 649 a proper type number?
