[RE-wrenches] Diode Failure

[Corey Shalanski]

Wrenches,

Since my previous post (see below) we have recovered the faulty modules and
are now looking to replace the diodes in order to make them functional
again. I have had no success sourcing replacement diodes from the original
module manufacturer, Mage Solar.

Can anyone recommend a source for replacement diodes?
