Hi All,

Thank you for the mine of information which resides in this forum!

I have just acquire a Lister generator, ST3 coupled to Brush SCTF 320.
There has been an incident in the past which resulted in a burnt cable (neutral/earth) to the control box on top, However the machine doesn't seem to have done a lot of work.
Cable replaced.

Thanks to the amazing information on this site, I have now nearly worked out all its problems.
I have a replacement silicon bridge rectifier arriving in a couple of days, and can make a heat sink in a few minutes.
Also, have managed to work out which cables are which at the selenium rectifier so that I can connect up the auxiliary field coils the correct way round!

While motoring over on the starter windings, it generates some 80 volts and is sufficient to lock up the decompressor solenoid, so all is looking good so far.
However, I have a question on the auxiliary field winding:  What should its resistance be - even approximately - please?
Measuring, it seems to be very low, almost zero.  Maybe this is correct, maybe it is a problem?

If anyone has a scan of the manual for the SCTF style Brush generator, I would love a copy.  There is one vital page on this forum which has helped a lot, but the rest would be magic.

Thank you in advance!
All best wishes
Chris Vine.
