Three-Phase posted:I just wanted to take a moment to say the unless you're in an explosion proof area that brushless exciters on large synchronous motors (>1000Hp and voltages >600v) are a tool of the devil. Maintenance wise it is a pretty dull job taking care of them despite the name. Brush gear is a fun weekly job. When our units are loaded there is about 2800 A flowing though those rings. Works out to around 60 A per brush.

I think that's the rear output but I could be wrong. Looks like the transmission crossmember failed and everything flopped down.

When I was a kid I was riding with my dad in his hilux down a dirt road when the driveshaft let go of the transmission and the rear end of the truck did a credible pole vault.

Holy poo poo, yeah. That's not gone well at all. Looks like the transmission extension housing snapped off just forward of the flange that attaches it to the transfer case  (pictured on the right side of your photo with 90K TESTED written on it)

ExplorerWhen I was building transmissions I saw a few failures like this. 99% time they came in on the hook fresh from whatever mud bog the driver was plowing through for kicks. So completely encased in mud. In the postmortem the case usually just ahead of the transfer case adapter and the bell housing were both broken. This can cause a lot of, "how is all that broken poo poo even sitting at that angle?" moments. But never on an explorer. Why? How? Who would even do this?

A Vanagon is the original VW bus, but "80s-fied" from the ground up. lovely vacuum and emissions systems, square plastic grilles that don't do anything, Atari-style wood paneling, high-profile tires, and a propensity for rolling over. Peak malaise. Further advancements in technology meant that all but the last feature was bred out before the Explorer was released into the unsuspecting public.

 More photos here quote:I built this aerodynamic modification for a Nissan Versa. It improved gas mileage from about 40 mpg to 55 mpg. It attracted a lot of attention on the road. I was going to drive the car to northern Quebec to Hudsons Bay. On the way, I was testing the mpg at 85 mph, and passed a truck north of Howard City, MI. The wind buffeted the car and somehow the tail exploded with a bang and was ripped off the car, along with the electric wiring and my license plate. I tried to go back and find it but it was gone. Since I had no license plate, I could not go to Canada and went back home.

All I need to know about hypermilers I learned when I read a post from someone who suggested that, when parking your car, you shouldn't stop at the first/most convenient parking space you come to, but coast around the lot in neutral until you slow down to bleed off that extra gasoline-energy you'd already burned. Then you line up with a space and kill the engine, hopefully coasting to a stop in the space without using the brakes. If you had to use the brakes, it means you didn't coast far enough earlier, and gave up some precious "mileage!" Because, you see, it's not actually about saving gas, but growing that miles per gallon number by any means possible.

To be fair to the hypermorons, the original, useful advice is to coast to the highest point possible (because parking lots are often times not completely flat...?) as to convert kinetic energy to potential energy. Still dumb.

I actually did this a lot when I still had my bug, the last quarter mile or so of my commute was super predictable and had zero traffic so I'd just kill the engine and drop it into neutral. I wasn't trying to save gas though, I just thought it was fun to see if I could find a spot before I ran out of momentum. Now my prius does it for me automatically even if it's in gear. Technology wins!

I sometimes coast into my spot from the entrance of the parking lot just to see if I can start with exactly the speed I need to land perfectly in the spot without putting it back in gear or using the brakes, but only if no one's behind me and I feel like it. Occasionally I also leave the tollbooths on the way to work in neutral, rolling downhill, because there's a traffic jam where it goes from 8 booths to 2 lanes and everyone's being an insufferable dicklord, so it makes it all the more amusing to simply manage my momentum and glide in in front of someone effortlessly without even being in gear while they alternately slam the gas and brake to try to prevent me merging because how dare I get in front of them instead of behind them  On the horrible mechanical failures front, however... I'm going to have to tear down my old 5MT from the Forester when it comes out sometime this week. Fourth is 100% gone for acceleration (it just makes ratchety noises over 10% throttle even when you hold the shifter back hard), only stays in gear for engine braking for 30 seconds or so, fifth pops out of gear about every ten miles on the highway, and 1-3 are making a loud raspy rushing noise, second also has a rhythmic clickclickclickclick overlaid over it. Betting that the dog teeth are about blown off of the 4th gear hub, fifth is worn badly enough that the back-cut on the dog teeth is mostly gone, most of the bearings are likely trash, and second is probably missing some tooth chunks or a whole tooth to sound like this. e:

When I lived up in the mountains in Colorado, I'd shut my car off at the top of this HUGE hill leading into the next town. This was about 3.5 miles. There were 5 traffic lights in the town. If they were all green, I could easily coast all the way to the other side of the town. I only actually did it twice, despite trying every week day for two years. It was all more about the traffic lights rather than MPGs. Another good one is when you drive down Pikes Peak. The downhill from the summit is rather steep. They stop you part way down to make sure your brakes are okay by measuring them with an IR thermometer. If you're over 300F they make you stop for one hour. My temperature last time? 60F - I only had to use the brakes once. Everything else was engine-off engine braking. What did I get? A pack of smarties from the ranger. OH YEAH! (Fluke actually uses the Pikes Peak brake check as a case study for their IR thermometers on their website)

There were 5 traffic lights in the town. If they were all green, I could easily coast all the way to the other side of the town. When I was 14 I had a hardship license and a 25 mile commute to high school. I did a lot of dumb poo poo but was a pretty experienced driver by the time my peers all got licenses 2 years later. One day my LeCar was exactly halfway between podunk and nowheresville with the gas gauge showing half a tank when I ran out of gas. After a particularly brutal soccer practice that afternoon I still had no option but to lace back up my running shoes and flip a coin whether to head to podunk or nowheresville. I jogged about 7 miles before a van stopped and gave me a ride into podunk. I bought a gas can and some fuel and jogged about 4 miles back towards LeCar before I caught a ride on a tractor. Long story short, I got really fuel paranoid in that car which leads to the relevant party of the story. I got into a primitive form of hypermiling and on the trip home there was a point where you could coast about three miles. One day I was getting close to empty so I turned the engine off instead of just idling in neutral. The problem was my reflexive action after turning off the ignition was to remove the keys and toss them in my backpack, which I did. Unfortunately, my long coast downhill had a turn and I entered it perfectly lah-di-dah until half way through my steering wheel locked up and I couldn't disengage from the turn and went bonk right into the ditch.

I-5 in Oregon.. was driving a different beetle, but I did the same thing I did for parking.. kill the engine, put it in neutral. There's three passes along that road if I remember right, and I could bomb down them at 75+ which is probably the fastest the bug I was driving at the time had ever gone. The elevation changes weren't super steep, I think the max grade was 5% or so, so you could coast fast without needing to touch the brakes. Don't do it in the rain though because that road is legendary for people wiping out while speeding.

You say that like I would want to be in an RV in the first place. When I'm on the road for more than 150 miles, I want it to be just the way it was when I was doing family road trips as a child; cramped, uncomfortable, and with as few breaks as humanly possible Also, how do you gently caress up power locks? They've been around for as long as 3 point seatbelts... which also got hosed up. Go Mercedes!

Killing the engine like you did works (beware of losing hydraulic assist, of course), but sometimes people think they’re saving gas by putting the car in neutral and idling the engine, and that’s simply not true. You’ll coast faster, but the engine has to burn fuel to keep turning. If you coast in gear, your kinetic energy keeps the engine turning so it doesn’t have to burn any fuel. It does slow you down a little, but on many grades that’s fine or desirable.
