Subject:      Update on the alternator story
Content-Type: text/plain; charset=us-ascii

So I just found a note on busboys web site that might explain the short life of my replacement regulator.

Here is from busboy's site: ------------------------------- http://www.bus-boys.com/charging84diesel.html Y. 070-903-803A Bosch Internal Voltage Regulator, Rectangular Housing with Brushes (30062), 1981 $18.00

Z. 068-903-803B Bosch Internal Voltage Regulator, Round Button Housing with Brushes (30091), 1981 to 1984 $53.85

NOTE: Voltage regulators must be installed like for like. Do not install a round button housing regulator into an alternator originally equipped with a rectangular housing regulator or vise versa. Damage will occur to both the regulator and alternator if these parts are mis-matched. ------------------------------

The Bentley manual of course said nothing about this. Bentley only said that a condensor should be fitted when replacing with a newer regulator if not already there. But I had that.

There seems to be a zillion different part numbers for the Bosch regulators, many which are likely compatible. Some that are not. Would this be the right replacement for the 65A Diesel alternator?

I agree with Dennis and others that it's time to start saving for a rebuilt. But I should have a working spare voltage regulator also. And that is a small thing that can be mailed to me quickly. Figuring out where to best buy (and how to ship at a reasonable rate -- I'm in Edmonton, north western Canada)

Another alternative is to look for a used alternator in low milage junk yard cars.

Do the alternators from any of the newer VW or other cars fit the Vanagon Diesel?

I understand that a lot of the 80's VW had a similar alternator housing to the Vanagon Diesel, but I may need to change the sprocket. However these are likely to have alternators as worn as mine.

Thanks, Martin (and Poppie '82 Westy 1.9TD)
