Alternator restart - Page 2

The small diodes are 3AF4. I bought them through Radio Shack and can be found through some Cessna parts suppliers. Last year I rebuilt this whole board and replaced the 85HF20 diodes (www.newark.com).
Attached is a drawing with part numbers.

Dan,
Rename the file without the spaces, and reload it. Even though we have the thumbnail, the file itself doesn't load.

Thanks, Dan.
It will be a great help to all.

Dan,

I assume the 300 884 number applies to the reed relays in each lower corner of the board. I can't locate this part number at Newark. Can you kindly provide more details as to where you located this specific part?

Thanks!

Scott

My alternator failure board is missing the relays altogether. Are the left and right relays the same part number? The printed board looks like the relays might be mirror images of each other.

I did find a few 300-884 relays for $116 each (and up!). I suspect this low-current relay is an industry-standard, inexpensive part, if anyone knows the specs or equivalent part number.

Scott,
I can not locate where I got these relays from?
Try part no. JRM-10631.

I found them at Computer Components, Inc. in East Granby, CT for $35! PN is 300-884.

Resurrecting this thread since I may be re-building my board soon -- would anyone tackle the task of figuring out what these components are called today? Perhaps then post a "shopping cart" from a popular site like newark.com or mouser.com with the modern equivalent of these items?

Like everyone else looking, I haven't found 3AF4 diodes in any search, nor the 300-884 relays.
