Hi Guy
I wonder if anyone would be able to help me out changing over my Allternator on my 3C.

The Battery has not been charging so I ordered a working one from a company Breaking JCB in the UK.
When it arrived everything looks the same for mounting although on the back the new one has different fittings on the back for the connections.

The Alternator currently on my machine at the moment has a 10mm nut fixing the main cable and a finer wire that has a smalll round cap to slip over a fine thread, but the new one need 3 slip on connecters.
Has any one got an idea of the type of Cap or a picture of the one that I need for my newer Alternator I need.
This may be a very simple fix or answer for someone but at this moment in time I have no clue of how I wire in my newer one and can not find anything on the internet to point me in the right way.

I will try and up-load a few pictures.
Thanks to anyone who can point me in the right direction on this.

The one on the right is my current Alternator still with wires connected.
Left is the newer one with back cover removed.






Above is the Newer Alternator with Back cover on and showing 3 connection points

Hi Mick,
Simply replace the connector on the fine wire with a small push on spade connector and push it onto the small spade on your new alternator.
Then use a larger spade connector on each of the two heavier cables which are secured by the 10mm nut and push them onto the two larger spades on your new alternator.

I wouldn't mind betting that the regulator and brushes had worn out in the original alternator, that's the thing with 3 bolts and a spade connector into it. I remember paying £150 to have a alternator overhauled and all they did was change the regulator, think you can pick them up for £14

Cheers for this Fred
So the 2 larger Spade connectors do not need to be wired in any order?

No Mick, the two large connectors join together in the alternator anyway.

Simply putting it.... Both large lugs are + positive, and the smaller lug provides the feed to switch the alternator warning light on/off
