Getting the electrical system put back together for testing, and things didn't go as expected. While the relay was definitely a problem, there was another one along for the ride. A bit of a frustrating end to the day for sure. And for those curious, the NC8 was just fine, no problems that we could find.

Good grief - I can't believe these guys have an NC-8 LOL. I was a 6077 in the USMC 71-75 and the NC-8 was brand new to the Navy. I spent a lot of time working on those things. Never thought I'd see one again. The sound of that thing running brings back a memory or two. Great work, gentlemen.

Brings back memories. As a Plane Captain (crew chief for non navy pukes), carrier attached A-6E squadron. We had 2 external power cord stations on aft end of the ship, that must put out a tad too much juice, so the A-6 wouldn’t accept power. Kinda like this video. We figured out , for those two power stations, we could get power on by Turning On a couple things in cockpit, usually some external lights, if it was a day launch. Very vague memory. Lol. Only 40 yrs ago. Lol. But this reminds me of that, but we knew we had a good airplane

While I only have very limited experiences with F-4's, since I was an Crew Chief on F-16 ,F-117A and later F-22's . I know enough that I appreciate the amount of work it takes to trouble shoot and rewire a fighter aircraft. The sheer amount wires stuffed into the tiniest spaces is mind boggling. The plus side was always that you always had a complete schematic TO for every system to help sort out the mess.

@Turboy65 2 ай бұрын

Current based troubleshooting: Unplug cables until the fault clears. The fault is down the LAST one you unplugged. I've used this system when troubleshooting complex F/A-18C/D simulator systems. Found a bad backup attitude/directional indicator in less than 15 minutes of work that way. Get yourself an Extech clamp-on ammeter that has both DC and AC read modes. They work very well.

@msgtdan60 Ай бұрын

Those wiring diagrams aren't as clear cut as they look all those flags are different mod numbers. You have to know which mods you have so you can trace the correct wires for the airframe you're working on. I once had to rewire the relay box that appeared under the WSOs right console on an F4E. About 20 different mod flags in that box alone. Not typically my job but I could read the diagrams and helped the guys whose job it was. My analog navigational computer was just outboard of it.

When you put ground power on did you turn on the ground power switch in the rear cockpit? It has to be on to get power to the airplane.

@DieselThunderAviation 2 ай бұрын

Not entirely correct on that. That switch (Instrument Ground Power) is a magnetically held switch that connects ground power to the Instrument AC bus. Under normal conditions the left AC bus (left engine generator) would power the instrument AC bus. That switch allows for ground power to power the Instrument bus, and since it's magnetically held when turned on (using ground power), drops out when turning off ground power or shifting over to the engine generators. Everything else not on the Instrument AC bus should turn on with ground power, including the right, left, and essential DC bus.

@robertschuler279 2 ай бұрын

@@DieselThunderAviation The ground power sw has to be manually actuated. It drops when when going to internal power.

@DieselThunderAviation 2 ай бұрын

Right, but you have to have ground power turned on first (and accepted) in the forward cockpit before the Instrument Ground Power switch can be used. That switch won't do anything otherwise if ground power isn't accepted by the aircraft.

I gotta ask-how could one get hot brakes landing on a 10,000 + foot long runway ? And anti skid-really ? Us Jugheads had NO such thing-anti skid-and at MCAS Kanehoe Bay-the pilots either engaged the MOREST gear or popped the chute immediately upon touchdown. K-Bay has a 7700 ft long runway & our rule of thumb fro hot binders was if one could get within 10 feet of the wheel/tire assy-all good. Either send 'em to the pits for a hot turn or back to the line. Anti skid........................ Same rule applied at El Toro-runways were a bit longer there-closer to 10K if I recall correctly.
