Emergency call….

Fundamentally, it was parts availability and reliability. There was a lot of stuff available in 24V that was a direct swap for many of the 24V parts. There was very little 12V stuff available.

These days, its a bit of a toss up – 24V stuff has largely been used up, so in some cases it may just be as easy to go back to 12V!

AR501 was on 12V up until its rebuild. I dont know what their plans are now.

AM design. … 24 Volt

Probably way off topic, but since the knowledgeable men are here, a question that was posed yesterday in my presence: what was the reason behind changing from 12V to 24V electric system in WW2-era RAF aircraft, such as the Spitfire? And do any of the surviving ones still use 12V?

Thanks Dave,

Indeed it did – parts found, and on their way!

Good stuff 😀

Yep I think so.

The USA won. (Yawn)

Not watching the football then? 🙂

Is there a game on, then?

Thanks Bruce!

Just been enjoying a cuppa in the garden with “the end user”.

He is mightily relieved, methinks.
