I have a mark II diesel engine fire pump controller. recently the pressure transducer started giving false readings causing the controller to start the pump. after troubleshooting we found the controller was not putting out enough voltage for the transducer to work properly . our firetrol vendor informed us the mark II controller could not be repaired due to being used in life safety equipment . we purchased a new one as the warranty on the old one was out for one month ! we would like to know if this can be repaired so it could be used as a spare . thanks !
