[ROVERNET - UK] Re: Need help - Cyclops voltage regulator

[Paul Smith]

It sounds like a high resistance in the cutin coil, I don't think I have one to measure (they didn't really change the design for many years) but shall check tomorrow.
In the event a later reg will do the job, I do not know if the connections are the same type (used to RB340s now).
The voltage should be around 13.5 when everything is connected and running.

It doesn't engage as the RPMs increase, allowing the voltage to climb
unrestricted.  If I manually engage it, then it works and keeps the
voltage in the 15V range, but then it disengages as soon as the revs drop
back to idle and will not re-engage.  I've cleaned all the contacts and
played with the adjuster screw but none of this makes any difference in
its behavior.    

I just had the generator rebuilt, and I think the voltage regulator
failure was what damaged the generator to begin with.

Any ideas?

Thanks - 

Geoff
