Jamie and I pulled the whole PZT driver for both PZT1 and PZT2.
Koji and I found that each HV power supply (the left-most module) has 2 fuses. Both HV supplies (PZT1 and PZT2) have one blown fuse. The "T2L250A" measures low resistance for both HV supplies, but the "T250mAL250V" measures Open for both HV supplies.
I have ordered 10 pieces of each kind of fuse, Next Day shipping, from DigiKey.
