I'm working on a Mata Hari. TP5 on the mpu should be 5vdc. But, I'm only getting 4vdc. On the rectifier board, I re- pinned all connectors and get the same result. TP3 on the rectifier board should give me 12vdc but I'm only seeing 10.5vdc. Removing JP3 from the mpu should give me a higher voltage reading but I'm not seeing the same 10.5vdc reading. I thought maybe BR2 was giving me the lower voltage so I changed it. Again, same reading, 10.5vdc on the rectifier board at TP3. This is low. I then thought it may be the fuse holder in line with TP3 on the rectifier. I changed this too. I'm still getting the same result. Anyone have any ideas? On the mpu the red LED is stuck on. No flash or flicker because It's not getting 5vdc.
