Following difficulty with our own Willys Jeep dynamo charging system we ended up developing a 6 volt to 12 volt conversion for the standard Autolite Dynamo regulator box as fitted to the wartime Willys MB and Ford GPW jeeps.

This conversion allows you to retain your original Jeep dynamo but running at a charge rate of 12 volts instead of the usual 6 volts.
The benefits or converting to 12 volts are greater cranking speed for better starting and probably more importantly 12 volt headlamps so you can actually see where you are going at night.

Details of the conversion:
The internals of the existing regulator are removed and replaced with modern electronic control. After conversion the regulator box looks exactly the same as it did and all electrical cable connections are still made to the original terminals on the regulator box.

What you will get :
Original dynamo regulator control box converted to run at 12 volts with a max charge rate of 20 amps (perfectly adequate for a Jeep)

What we need from you :
You need to supply your original control box for the basis of the conversion, this need not be working but it must be complete with base, lid and internal circuit board onto which the terminal lugs are fitted.
Later on we hope to have a supply of regulator boxes so that we can sell complete units but until then we can only convert your own existing parts.


When you pay with Paypal you will then need to post your existing control box to use for conversion.


Typical turn around time from receiving the control box is 3 to 5 days but at busy periods please allow a little longer, we will send out your converted part as soon as we can.

As always please CONTACT US for more information
