Are the two regulator types interchangeable?

Indeed. However, as I lack the proper test cable or access to such, I am forced to improvise. Your PDF file is extremely helpful and very much appreciated. Reading through it again I see that I stopped one step short. I have now completed the testing on page 25. I get 4.2v as described in step 4. However, at step 6 I detect no voltage. I still need to test the cable before concluding that the alternator is defective. Thank you, mdh

Well, I finally got a few moments to do some more troubleshooting. I decided to see if the alternator is actually providing voltage to the distribution box. After studying the system I decided to disconnect the large cable at the distribution box. I then fitted appropriate wires to the pins and inserted them into the sockets being careful to maintain the correct routing and leaving the pins exposed so that I could attach a voltmeter. I assumed that the main charge would be from the two very large pins. With the engine running at approximately 1500-1800 rpm I measured only 4.2v. I also measured every possible combination of plugs and ground. I got 4.2v at a couple of places and 3.1v at another couple and nothing at the remainder. Does this indicate a bad alternator or cable from the alternator or is my major premise of 28v at the large pins wrong? Thank you, mdh

I am going to attempt to attach a pic of the plate attached to the hull. However, i am unsure if the size is small enough to be allowed. If you are unable to read it please let me know. Underneath the plate the hull is inscribed with 2126 9 59. JUST VIEWED THIS REPLY AND REALIZED THE PIC IS UPSIDE DOWN. Let me help... CAR SCOUT RECCE FV701H MK2/3 MODEL B 1952 CONT. No DAIMLER VEH. No 76MS83 CODE No CLASS OF REPAIR DATE WKSPS. No INSPECTION REBUJLD 23BW 7/72 2126959 mdh

Thank you again for the assistance. Will check out Mark's site. mdh

Will get the hull number in a few days. At the moment I am away from home base for a bit. mdh

Thank you. That does indeed help. I didn't realize that wild cards were allowed. mdh

A thousand thanks! That is an extremely useful link. Just what I was seeking. Hopefully I can find a counterpart for the Fox. The number stenciled on my Mk2/3 Ferret is 03CC37. However, I have discovered that number is also on another Ferret in the UK. Again, thanks for the help. mdh

I have most of the necessary manuals for my Ferret and Fox. However, they are poor quality reproductions and many diagrams and photos are extremely unclear. Is there a source for GOOD quality manuals out there somewhere? Thanks, mdh

I can't seem to get the search function to work properly. Specifically, if I search all forums and posts for "fox" nothing is found. However, I know that there at least a few posts containing "fox" because I have made them and have received replies containing "fox". It's probably something simple I'm overlooking, right? mdh

I did find a few connections that were partially broken and resoldered them but that wasn't it. mdh

Not a stupid question at all. Unfortunately, the belt is intact so it's not that simple. mdh

Wow! Fantastic resource! I have downloaded it and will study it carefully. A million thanks. mdh

Well, I pulled the distribution box and opened it up. There seemed to be only a slight bit of corrosion on the contacts of the big relay. I gingerly cleaned that up. There were several smaller relays. They seemed to be fairly clean so I left them alone. I then replaced the box but nothing has changed. The alternator light is still on and the ammeter does not move. A VOM shows no charge delivered to the batteries. With the engine running I applied a battery charger to the batteries but the light did not go out or dim and the ammeter did not move at all. Does this give you a clue as to what might be the problem? I'm going to remove the box again this weekend and see if the main relay will operate if i apply voltage directly to it. Thanks, mdh
