Dynamo spade connector

[TOMO28B]

Hi all,anyone know what size the dynamo spade connector is,as mine has corroded badly and is causing ignition light to illuminate. I must have every type of electrical connections in my box of tricks except these connectors. I done a rough size across the connector and it seems to be about 10mm in width. Any help please,thanks.

about 10mm

Back when these were made it was likely imperial?

Male or female connector? 10mm is around 3/8”

The large spade connector on the Minor dynamo is 3/8" or 9.5mm wide.
The small spade connector on the Minor dynamo is 1/4" or 6.1mm wide.
If either of the male 'spade' connectors are the ones on the dynamo it may be easier to obtain a good S/H dynamo than try and repair the connections.

It's the female connector that's corroded,the male one is in surprisingly good nick.

I'm assuming it's the Large one you're speaking of, since a voltage drop at that, being the output connector, would result in lower voltage being sensed by the Ign Lamp.
A standard Yellow 10mm is what you need, but they are best fitted with a ratchet crimp tool.
