CAV 24v Generator

Question

Can anybody tell what this generator fits please. It's new old stock in a crate and I suspect it's an underfloor generator for an Austin K9 or similar for charging batteries, but I'd be glad if someone could confirm from an old CAV parts list or similar -- thanks

Unfortunately this dynamo is not listed in 1955 edition AP1086 Section 16E (RAF MT Electrical items) as it does list applications.

 

In general Army catalogues & EMERs rarely list applications.

 

Looking in EMER POWER O 122/2 it lists G7A24/7X & G7A24/22X. They are similar except that four dowel holes are provided in the yoke for alternative mounting positions & the dowel pin is not fitted. This change is indicated by the advancement of the number 7 to 22 in the type code.

 

It has an output of 27v 55A at 1,450 rpm cutting in at 1,150 rpm. Two 0.5mfd capacitors are fitted for RF suppression indicated by the letter X.

Thanks for the reply Clive. Would you say that the outputs are the same and the differences are just the positioning of the dowel pin holes? If so then I guess it would fit in the brackets under a K9 if the dowel pin was left out. Would you know if the electrical connection is the same?

 

Thanks Armoured Farmer for correct part number for the K9

 

This dynamo is for sale if there is any interest
