Inquiry (采购产品): sun tach magneto transmitter I have a Sun tach and a magneto transmitter. the transmitter takes a Mallory RM12R mercury battery. 1.35V. I understand these are very hard to find if not impossible. Looking for substitute or replacement. Any help would be appreciated. **** Hidden Message ***** Alan R.
