Beech F33A Electrical System Repairs

The F33 has been plagued lately with a problem of the low voltage light coming on accompanied with an ear-piercing squeal through the speaker/headphones. The only way to stop it was to turn the alternator off, then back on again. The ammeter didn't work, but the pilot thought there was no problem with that because he had a JPI. What he didn't know was that the JPI shows buss voltage only and not amp load. The only way to tell if the alternator system was working was to see if the buss voltage dropped. So, after further investigation, here is what I found. I don't believe that you could burn this shunt worse if you used a torch. 

 So when I replaced the shunt, I noticed the terminal block and the fuse holder looked like it had been down 40 miles of bad road, so I opted to replace these at the same time. Used new wiring and terminals since the originals looked like crap. So here it is all wired up and ready to go. Got it in and everything seems fine now. No squeal, ammeter works as advertised, etc. All in all it came out pretty good !
