A couple of dumb questions. 1. What truck is this on? 2. What kind of system are we looking at (neg ground, pos ground)? Maybe, if we know about what you're working on, we can help more. But, here are a few things to think about. Sometimes, the best way I have found to troubleshoot electrical systems is to start disconnecting individual systems/circuits (regulator, generator, ignition switch, etc.) and see if the situation changes. I have seen a bad voltage regulator bleed one dry in no time. Disconnecting it stopped the bleeding. Maybe you can disconnect a terminal at a time from the junction box and see what happens?

Passed a Transtar Eagle cabover this morning. Tried to get the camera out, but was too busy negotiating traffic. Decided to just take a mental snapshot. Click.

That's kinda interesting! Might need taller rear gears? Depends on how fast you wanna go.

Did you ever figure this out? I have never swapped a generator equipped piece from pos to neg ground, so I am not sure if that would work or not. But, my R just had an alternator put on it (integrated regulator). Cables were swapped and it worked. Only thing I had to do was replace the volt meter. Original was a single post, so there was no way to "reverse" it. I put in an aftermarket 2-post unit, so I could reverse the polarity at the gauge. I'm not sure, but there should be a way to either make that regulator work or there should be a similar neg ground regulator that would work. Curious what you figure out.

ENDT-673 was absolutely offered that late. ENDT-675 was introduced in mid-60s as an option. If it has a factory Quad box, it SHOULD NOT have the 675...not from the factory at least. 250HP ENDT-673 with the Quad was a common configuration. Oh, on my '70 R600, it was stamped "T-673C" on the RH side of the engine, on the gear case. That made it the ENDT-673C engine. It was marked 250 HP on the tag on the valve cover. Also, this engine was standard on that particular model number: R611. The R611 was a Thermodyne powered model. The ENDT-675 mentioned above (237 HP Maxidyne) would have come in the R685. So, check the serial number stamped on the RH side of the frame, near the rear hanger for the front spring. The one on the door may be right, or the door may have been changed. Lots of good info on here about what the various model numbers told you about the truck. Hope it works out for you.

Yip. It's not the "demountable rims" that make them wobble. It's the guy putting them on. It takes a little time and patience to put Daytons on correctly. Good wedges are a must, and are often overlooked. I liked that a Dayton spare was lighter to handle, and that you didn't need a gorilla to break them loose. A few years back, there was some good discussion on here about techniques for getting them on not only straight but tight. Usually involved a sledge hammer or a hardwood maul! Funny, but when I was just a little one (4 or 5 years old), I always associated the sound of a diesel with the look of a spoke wheel, and the sound of a gasser with discs. That's because every Mack we had came with diesel engines and spoke wheels, and all the C60s and F600s came with gas engines and disc wheels! That's just how the world was! LOL!

Congrats!

I have also seen worn out kingpins cause a shake.

I know all of the ones we had were 12V positive ground, but some had a 24V starting circuit.

That reminds me of something I saw in town when I was a teenager. My buddy's dad ran an auto parts store in town. We frequently used the alley behind the store to come and go through the back door. Across the alley, there was a small textile plant. In the middle of that alley, the textile plant had a loading dock, coming off the alley in a "tee". There was a wide spot there, but nowhere near enough to back a trailer into...or even pull it out. Occasionally, we would see a "pup" trailer at that dock. But, we could never figure out how the driver got the trailer in there, as there was not enough room to swing the tractor nose within that alley. At best, we figured you could only get about 75% of the way in there. One day, we caught the driver swapping out the trailer. Was the coolest thing I had seen (to that point!). He backed the rig down the alley, and kicked the trailer into the tee as far as he could. The tractor was pretty much against the opposite wall. Then, he unhooked from it and drove around the block. He would then back down the alley from the other direction, and re-hook to the trailer...at an almost-jackknifed angle. When he pulled forward, the trailer squared up to the dock and just touched the wall. To remove it, he did the opposite. He would hook to it from the 2nd side and back up as far as he could without the trailer hitting his cab. Then he would back in from the 1st side, re-hook, and ease ahead. Have no idea how they figured that out the first time, but he made it look easy! Wish we'd had camera phones back then!

This guy has some awesome stuff on his website. Check him out, if you don't already know about him. https://mackmacktruck.com/mack-truck-restoration-by-mickey-delia.html I love the yellow/black R-600 he did for Stavola Brothers. That's the paint job I always loved.

This one lit up out behind the plant a few years ago. What alerted me to it was 2 big "booms" when the front tires popped. Nobody hurt, thank goodness.

What the...?

From the Baltimore Sun some time back. Luckily, no injuries.

That's for "power steering"!

I think it's the retro-entabulator holding it up there! Or, maybe the hypoofenator!

Years ago, I was working at another of our facilities. One of the guys who came to work there with us had been and owner-operator, and had recently hung it up to be able to stay at home more. Pretty cool guy. We had lots of talks. Lots of them centered around trucks, naturally. Anyhow, I had been on a recent road trip, and had passed by an older cafe on the way. It was a place I had passed numerous times, but I had never had stopped there. I noticed it was now permanently closed. So, I asked that guy if he knew the place. He said he knew where I was talking about. He then proceeded to give me a real history lesson! Apparently, he had encountered that same cafe on a particularly tiring trip. He wanted to rest and get a bite to eat, so he finagled his rig into the rather tight parking lot and went inside. He sat down at the counter, and waited for a server. Nobody ever came over. Nobody ever brought him a menu. So, he finally moved over to where a man was sitting at the counter talking to the woman behind the counter. He asked the woman if he could get some scrambled eggs. She said they didn't have any eggs. So, he asked about getting a cup of coffee. The woman got a little irritated and said, "There ain't been a cup of coffee poured here nor a chicken laid an egg in 20 years. Do you want some p...y or not?" He decided just to ease on down the road! The way he told that story was great, and I laughed till I almost cried. I still lose it when I think about him telling that story! That place is long-gone, but that memory will live on as long as I do!

Before I started using Opti Lube, I did actually use 2-stroke oil in the old R600. It did show a noticeable improvement in lubricity in the study I have referenced before. But, the Opti does more than just that. A lot of the available additives didn't do much for lubricity, and some stuff actually made it worse. I guess it depends on what you are asking from an additive: anti-gel, lubricity, cetane booster, water separator, etc. I mean, if somebody gets what they want by putting a dead possum in the tank, go for it! I don't judge!

Check out these guys. They have at least SOME of the ones that match up with factory stuff. The bullets they have matched up with the ones on my old R. EMTS parts used to have some also, but they don't appear to have too much any more. Not sure if any of this will help, but it's all I've got! https://www.slclighting.com/search-results-page/marker%20lights https://www.slclighting.com/product-page/cab-marker-chrome-high-impact-amber-incandescent Also check out this conversation from a few years back...

Yeah, I believe it has been raised, and none too soon. But there are still plenty of videos out there of The Old Can Opener!

But, isn't it still nice that SOMEBODY noticed, and took the time to acknowledge, the skill required?

The driver sure was lucky in that one. A foot or two sooner, and the whole rig would probably have went straight down onto the lower level. Could have been VERY bad. On some of the others you guys posted, I sure hope nobody was seriously hurt on those. Abrupt stops and "unintentional convergences" with bridges can be hard on people as well as equipment. Do you guys know this website? http://11foot8.com/

Nicely done.

Good to know. Didn’t really plan to order from them. Just thought the shirt was cool. But, again, thanks for the heads-up.
