Those units are notorious for the module going bad. I have a Mallory dist. and mine went bad not long after I had it. 
Make sure you read all their warnings about what NOT to do with them.  
Jump starting your battery with the module hooked up will GUARANTEE spiking the module! 
I recommend also buying Mallory's spike suppressor. It's cheap insurance against failures!!
