44GPW Posted April 3, 2016 Share Posted April 3, 2016 Hi guys Struggling to find a replacement for my faulty CAV control box so have been looking at the possibility of fitting a Dynamator. Has anyone done this on an MW or similar or does anyone have any thoughts on it? Thanks Richard Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted April 3, 2016 Share Posted April 3, 2016 Hi guys Struggling to find a replacement for my faulty CAV control box so have been looking at the possibility of fitting a Dynamator. Has anyone done this on an MW or similar or does anyone have any thoughts on it? Thanks Richard The electrician I used has converted many of these CAV units for me, to a later control box by transferring internals. He then sets the box up to the dynamo on a test rig. Sadly he is not available to take on work now, but any good auto electrician could do this. Quote Link to comment Share on other sites More sharing options...

44GPW Posted April 3, 2016 Author Share Posted April 3, 2016 Thanks Nick, that certainly looks like a really good possibility? May even fit inside the housing of the original CAV control box? Does anyone know the exact make and model of an MW dynamo? I believe mines an original. Thanks Richard. Quote Link to comment Share on other sites More sharing options...

Hi, Chris Morter has reconditioned control boxes fitted with modern internals available off the shelf for around £100 exchange. If the dynamo is the same as on the OX it is a CAV one, but not sure of the exact model. Regards, Mike Quote Link to comment Share on other sites More sharing options...
44GPW Posted April 4, 2016 Author Share Posted April 4, 2016 Hi Mike, Well that would be perfect if it's the same. I will give him a call today. Thank you very much for the heads up!! Cheers Richard Quote Link to comment Share on other sites More sharing options...
wally dugan Posted April 4, 2016 Share Posted April 4, 2016 The dynamo fitted to the two MW here at the moment are both CAV type D46DH81 if that helps Quote Link to comment Share on other sites More sharing options...
44GPW Posted April 4, 2016 Author Share Posted April 4, 2016 Hi Mike, You are correct!! John Mortor does them £105 plus the old unit in exchange. Only difference is that it needs to be wired Negative earth. From the outside they are original CAV's, but have modern internals. Perfect solution.....thanks for the heads up.

Cheers Richard Richard, Negative Earth is correct for a Bedford MW anyway. Quote Link to comment Share on other sites More sharing options...
44GPW Posted April 4, 2016 Author Share Posted April 4, 2016 Really?? I Wonder why he thought it would be Positive earth? Oh well, even better. Thanks. Quote Link to comment Share on other sites More sharing options...
44GPW Posted April 5, 2016 Author Share Posted April 5, 2016 Here's the converted control box. Not much to look at inside but hopefully the end to my charging issues!! Quote Link to comment Share on other sites More sharing options...
GeePig Posted April 6, 2016 Share Posted April 6, 2016 Here's the converted control box. Not much to look at inside but hopefully the end to my charging issues!! Nice! So you now have a control box resembling one of those Russian dolls, a box within a box... trev Quote Link to comment Share on other sites More sharing options...
