Converted my Rev 2 turbo alternator to a round plug using a N/A alternator and bracket

Car decided to have a paddy today and the alternator stopped working.

Ah I thought I have one still attached to my N/A engine I will use that.

So I go and take it off and do a comparison, its slightly smaller and the plug is round instead of oval, right I thinks this shall not stop me so I proceded to take the top section of the alternator off and swap it over.

Was a very simply job in the end except the that I had to change the bracket aswell.

Anyway the point of this post is that if your alternator decides to go t1ts up and you can only get your hands on a round plug and yours is oval (or vice versa) dont dispare as they can be swapped easily, just dont try and use a N/A alternator as you will have to swap the bracket over to and thats a PITA.

How to.........

Remove 3 nuts to take cover off.

Remove 4 screws around edge (easy ones)

Remove 4 screws (use a good screw drive as they will round).

The reason I seperated these to section is because the B+ connector was different between the two, may vary depending on type but you will see when you do it what I mean.

Finally I had to cut a small section out of cover to allow room for oval plug.

Good luck.

good idea ,But the bit you are changing ,the regulator ,in some cases will be the defective part

Of course you are correct but if someone where doing this job I would expect them to know the actual alternator was defective and not the regulator.

Not everybody will know which part is defective though so guess I best make a amendment or maybe you could. [Laughing]

Have a look in the BGB mate.

Check out the alternator section.

http://www.mr2-tech.com/bgb/mechanical/volume1/charging_system.htm

This gives you a idiots guide to a almost full check of all alternator components.

Unfortunatly it doesnt show any values/readings for the IC regulator but, it does tell you the values/readings you should get from all the other components.

So all you need to do is check the other components and if they are all within specified limits then you know its the IC regulator.

Hope this helps, and maybe 3sgte will be along with the correct values/readings for the IC regulator as he was the one that mentioned it. [thumleft]
