BC348 dynamotor restoration PT1 initial testing
The carbon brushes on the 28V side were seized so I had to replace them. Obviously BC348 dynamotor brushes are made from unobtanium but I found something close on eBay
www.ebay.co.uk...
There are a number of sizes offered but the 5mmx8mmx14mm are a close fit if you shave a few mil off each side
The dynamotor seems to be in reasonable condition and having droved it works I will move on to restoring the end caps and electronics
