  1. I remember when the C-130 gunships were leaving Korat RTAFB in '75. They were using the entire runway to get off the ground because they were so heavy. My neighbor from downtown was a loadmaster, and he had all kinds of stuff he was taking with him, including two huge bags of Thai hot peppers.

  2. We know two things. There is 28 VDC going to the radio, and the radio is turning on via a ground from somewhere. I don't have the connector layout for J2, but is Pin A anywhere near pin U? Here's what I would do if I was working on the aircraft. Remove the ground terminal lug from the aircraft frame going to pin A on J2. I would think that if you removed the power and chassis grounds lugs going to the chassis and power grounds of J1, pins P & E, that the radio would be dead.  

    Having said all of this, it may be worth getting a new plug for J2, and pulling all wires out of the old plug, verifying wire numbers, and repinning into the new connector. Good luck.

  3. It is the same battery. The amperage supplied is different depending on how fast the battery is discharged. I just posted the paragraph out of our newer electrical maintenance book. The USAF does not use the 1C-130B-2-7 any more.

  4. Someone just can't send you the book, it has to be requested from Warner Robins ALC. If a person sent you a copy of it, it may be out of date. If you need further help, let me know.

  5. The date's on my iPhone calendar, I'm safe.

     

    Mazurb, if it was a test installation, the wires should be orange. You may have to cut some string or tiestraps back to identify the wire number. Since the breaker is strapped, why not remove the breaker, then cap off the wire? 

     

  6. We had that aircraft in Alaska at one time. I know on the pilot's lower circuit breaker panel there were two, but marked VHF XMTR and RCVR. The regular VHF circuit breakers were on the co-pilot's upper panel from what I remember, but it has been a long time. I don't know if that aircraft was sent to Yokota before Little Rock or not, but it was one of our regular H models.

  7. I don't know what kind of C-130 you are working on, but no USAF aircraft that I know of has ever had the HF radio tied into the WOW circuit. My out of date jacking book doesn't show pulling the breakers. I remember they had to be strapped to go into a hangar to prevent the HF radios from transmitting.

    There doesn't seem to be a rhyme or reason for some systems to be secured. All it takes is one incident and the engineering staff will put something in the book to prevent it from happening again. Even if the HF wiring went through the WOW circuit wiring, there's no way it would cause it to transmit without hitting a MIC switch.

    All of this being said, I've been retired for four years. Maybe it was decided that the HF shouldn't be able to transmit on the ground at all for safety reasons. That would mean that the WOW switch would have to be jumpered to enable an Op Ck. As Natops1 said, check with your radio guys.

  8. Not sure exactly what you are looking for, Bob. I still have some old T.O.s but they don't show the whole panel. LORAN was a huge long receiver box and a green glass tube screen display next to it.
