BMS trouble

I've been getting communication faults with my Elithion BMS.  The BMS plays several roles.  It is responsible for turning off the charger to avoid over-charge, disconnecting the load to avoid over-discharge, as well as doing the same to avoid any over-temperature conditions.  The faults originate in one or more of the cell monitoring boards attached to each cell.  By observing their blinking pattern I believe at least 2 are faulty, both of them are nearest the opening of the hood which makes me wonder if the elements are too much for the PCB.  In the front all that protects them is conformal coating and the hood.  

old car "stuff"

Brake booster went out.  No power brakes and drawing excessive vacuum.  Ordered an aftermarket replacement and learned that car is a 2002tii and that the tii requires a differently sized booster (to make-way for some fuel injection parts) - the tii means that it was originally fuel injected.  It was carbureted long before I got it.  So to avoid redoing brake lines the correct booster had to be found.  This turned out to be a hard-to-find part.  

A shop in town send mine to Dallas to get it rebuilt.  A week later I received it back with news that it couldn't be rebuilt.  Finally a shop in California rebuilt it for a reasonable fee.  The car was out of service for about a month.
