Morris Minor Owners Club

my car has had an alternator put on at sum point and the past owner and left the old wires, can i just remove these also can i remove the box next to the fuse box

thanks tom

Look at the wiring diagram for your car and work out what they should do and check if they are live before removing them. When fitting an alternator the control box is rewired so that it acts as a junction box.

okok thanks ill have a look and could i just connect the wires on the control box and remove it

thanks tom

Depends if they are being used or not - the 'clever' way to fit an alternator just uses the original wires - connected slightly differently of course.

There should be a diagram on here somewhere

Here's one - instead of 'new wire' - you can just use the original D and F wires, and connect them as shown.

So, unless you want to retain the old control box, surely you can just remove it and join A and A1??

well i blew mine and i have a wire conneting the termials i know its not gud but as said above can i not just join them and remove it ??

Yes - just join A and A1. Some like to keep the box - for originality! The point being - the wires in the harness that went to the dynamo can be used to power the alternator. No 'new' wires required.

not to bothered about orignality , gettin resprayed black in 2 weeks with a line of checkereds down the side like an american taxi

That sounds nice Tom
Was the voltage regulator only to even out the votage from the dynamo? I too am fitting an alternator and have removed the whole loom to tidy it up and would be very keen to remove the voltage reg if I can, so it's just simply a case of joining A and A1? Can the rest of the wires just be removed?

The Volts Reg does exactly what it says on the box! It regulates the dynamo charging voltage - and also disconnects it if it's not going fast enough to generate a charge. All this is taken care of electronically inside the alternator - so no need (in most cases) for an external regulator.

Right on, definitely coming out in that case. Can the rest of the wires (i.e. other than A and A1) be removed?

There only are D and F - not used with an alternator!

Gotcha, cheers

removed the old wires and looks a lot better just need to join a and a1 wires now

I have been following this thread carefully. Thanks for the clearly explained wiring diagram. I am thinking of ordering a new wiring loom for my pick up and as I will be fitting it with a 1275cc Marina engine complete with alternator, I will order the loom with alternator specification, thus I assume this will do away completaly with the dynamo control box. Is there anything else I should look out for when doing this conversion to alternator?

Thanks

New loom
Make your list of all the "additional " pieces of electrical equipment you need/ want ( now and in the future ) on the vehicle,
e.g.hazard lights, rear fog lights, spot lights, clock, etc.
In relative terms it's best to get these incorporated now rather later ( adding loads of extra untidy wiring ).
You can leave some connections "unused" until you find the necessary funds to buy an accessory
Alternator
The longer the above list gets ....the greater the electrical load becomes for an alternator to power.

Really no great need for an alternator - unless running lots of extra lights ............ Be sure to go to negative earth though - if you DO fit an alternator.
