A quick update.
Thanks to Richard, I spoke to Paul at Smart Power and he thought my Dynamator is probably ok as it's been working for the past 5 years. My auto-sensing meter could be detecting ripples on the output, so I borrowed a simple multimeter set to Vdc and the readings were all ok:
Standing battery 13.54V
Engine at 1000rpm 14.38V
Tickover 650rpm 12.65V
In conclusion Paul said the Dynamator is a bit of a compromise between physical size and output. At high loads they have been known to overheat and cook the diode assembly.
Many thanks for all your comments and advice.
Jim

Re: Dynamator output
Excellent news, Jim, with the issue now solved hopefully; certainly seems like it from your new figures.
Regards.

Re: Dynamator output
I'm intrigued about that "auto-sensing" meter. What make and model is it ? Try it on a car with an alternator and see what it does there.

Re: Dynamator output
Hi Brian, the meter is designed to carry out all the tests necessary on an electrical installation, Megger MFT. That's what I did just before I retired
I tried it on my daily driver which has a standard alternator and it registered pure dc volts across the battery whether the engine is running or not. That's what lead me to believe there was a problem with the output of the Dynamator, hence my OP.
