Does anyone have a wiring diagram for converting an old tractor wiring
system from 6v (dynamo) to 12v (alternator)?
Thanks

Why do you want to do it twice? ;-)

No, because just about everything will change

- the ignition system will need a new coil, if its petrol
- all the bulbs in it will need changing
- the starter motor will need changing
- if its diesel, the glow plug(s) will need changing.
- the dynamo and regulator and battery will need changing.
- most of the fuses will need looking at.


If there is anything else electrical on it, apart from tehe odd switch,
that will probably need changing as well.

You haven't said what tractor you have, but I converted a BSA 3wheeler
without too much trouble.
You will need a new starter motor, finding this may be the hardest part of
the conversion.

The dynomo will certainly use one of those old electro mechanical
charge two or three bobin regulators. That will need to be removed and
the wires isolated. Modern 12v alternators are all pretty much the
same...

Built in rectifiers and regulator. A ground terminal/casing, a warning
light output and the main +ve output. The later needs to go to the
battery +ve.

Battery, starter motor, ignition coil, all lamps, instruments etc. will
have to be changed to 12v versions. It might be possible to have the
starter motor rewound to suit 12v, lamps should present no problems. It
might be possible to get instruments to work correctly by inserting
resistors into their 12v supply.

Other than the above, any modern car circuit diagram will provide
enough clues.

Because he wants to fit a stereo ?

You can usually use a 6 volt starter on 12 volts.
