Adam the reason the oem diodes blow is they are underrated for the job (surprise surprise). You need to buy some high speed high current (>20A) diodes to replace them, and also add in a few protection diodes to the underside of the board. There are several different versions of the board - I have never seen the one you have and I've seen three different versions in addition to yours!
