As you can see... the 034 and 036 battery areas are completely different.
I'm not sure if the factory had the battery vent externally or not. The simple solution today is a sealed AGM battery.

They did NOT have a venting tube arrangement from the factory.


So I miiiiight be imagining things... but the car seems much more responsive at part throttle with the new harness.
#placebo
Nice to see the upper harness done. Mine is parked in the garage for some time now and need to get some work done now that weather is warming up.
So Klink... since these didn't come with venting capability from the factory... am I worrying about corrosive gasses eating away my trunk for nothing?![]()
Yeah, pretty much. The biggest thing that contributed to trunk rot was people overfilling the batteries. The next biggest contributor was leaking batteries, and/or non-DIN spec batteries with poor vapor control. The third major factor is people over-charging and “boiling out” the electrolyte by using dumbass chargers and dumbass methodology. The factory started adding the exterior venting as a safety measure to prevent accumulation of explosive gas is during an overcharge the situation, such as with a defective a voltage regulator. The first Mercedes-Benz to have it, in my experience, was the 210, which had the battery under the rear seat cushion, and this good practice persisted with each new model introduced, The only exception being the 170 SLK, which had the battery mounted under the hood. Interestingly, those added a tiny vapor/droplet catch tank on one end of the battery, and a blocking plug on the other. Regarding that plug, let me point out that most people COMPLETELY BOTCH a battery vent install like this by not installing an appropriate PLUG in the opposite end of the battery housing! It is omitted by careless and/or lazy ne’er-do-wells during most battery replacements. Even on most cars with factory venting, you will find that if the battery has been replaced, there is no plug in the opposite end of the battery, even though dealer batteries are conveniently supplied with a plug which can be easily snaped off of the shipping cover for the positive terminal. Without the plug, there is no particular reason for the gases to not keep just venting to the interior. But to repeat, when everything is OK, there are no acid vapors to be concerned about. Don’t overfill the battery, and don’t overcharge or overheat the battery. If the battery happens to leak, the venting does you no good, anyway.
*salute*
You’ll be happy to know that did install the plug on the opposite side of the battery
Thanks for the background!

What brand AGM do you have, Louis? I looked at photos of my Die Hard and Delco AGM's, and neither appear to have provision for a vent tube, on either side. I thought all true AGM's were sealed and ventless...? I'll check a couple of my OE MB AGM's at home for grins.mine vents (AGM) and is plugged on POS side.![]()

I see some resemblance with GSXR....

Ahh. One awesome experience i had this morning that I forgot to relate.
Got up a little early to grab us coffee. Headed out in the 420 since it was the only option (probably would have used it anyway) get there just fine, grab the brew, head back to the car, unlock the doors, stick key in, turn. NOTHING. I mean absolutely nothing. No buzzer, no slow crank. Dead silent.
After a small meltdown/panic attack at the good luck of having two cars go tits up within two days after selling a perfectly good one... i remembered the battery tray work I did a week or so ago.
Popped the trunk, removed the battery cover and touched the negative terminal , which seated the cable more firmly on the post. Turns out this bozo didn’t tighten the cable bolt, and it had come loose just enough to prevent any current from flowing.
Car started right up. Crisis averted. *phew* :releived:

I think this is in the Idaho driver training manual, since every car on the road appears to purposely do this. It's like they're trying to encourage road rage.... coupled with a population that can hardly handle their cars on a bright sunny dry day makes for some awesome motoring. (seriously, this is one of the only places on earth that the left lane is guaranteed to be blocked with someone driving the exact same speed as the guy in the right lane, acting completely oblivious to everything going in around them. Made all the more frustrating by the fact that they’ll drive at slightly different speeds inconsistently, giving you a sliver of hope that they will pass or fall behind the right lane enough for you to get around, but don’t worry... it will never happen)
Bonus! And, your exhaust pipes look immaculate, much better than most IMO. The heat shields & bolts usually have at least a little corrosion.Got the lower panel off and was surprised to find an almost new oil pan!!
LOL. Yeah, it's not good, but I've seen waaaaay worse. When there's no insulation visible at all and it's just bare copper everywhere, that is toast.The lower harness is TOAST!
I think the spec is correct, it's a pretty large diameter bolt thread. I must admit to not using a torque wench on the pan bolt though, but Klink calibrated my arm via Teamviewer so it's all good.Oh... i think the FSM is wonked on the drain plug torque spec. 40nm seems awful hefty for that small bolt and pan!!! Am I crazy?
Nice post. I feel your pain with NW drivers antagonistically hogging the left lane just because they can. I can also relate to that feeling when you turn the key and nothing happens. Not a good one.
...If I ever meet this cop, I'd like to buy him a couple boxes of donuts and all the coffee he wants! (Skip the first 30 seconds.)

I know. And in my case, its usually successful!I think this is in the Idaho driver training manual, since every car on the road appears to purposely do this. It's like they're trying to encourage road rage.
Thats great to hear. Steve had similar comments when he did the alignment a week or so ago. The car lived most of its life in CA, with a short stint in the Houston area of all places.Bonus! And, your exhaust pipes look immaculate, much better than most IMO. The heat shields & bolts usually have at least a little corrosion.
Ok! I just felt i was starting to strip the pan out before i got to 40. Maybe I was just being overly cautious. I ended up giving up on the torque wrench and just snugged it up by hand. Went for a drive and they’re wern’t any leaks, so I think its OK.I think the spec is correct, it's a pretty large diameter bolt thread. I must admit to not using a torque wench on the pan bolt though, but Klink calibrated my arm via Teamviewer so it's all good. [emoji3]
God. That is great.If I ever meet this cop, I'd like to buy him a couple boxes of donuts and all the coffee he wants! (Skip the first 30 seconds.)

No one pays attention to the signs on Washington Highways that read "Left lane for passing only".
If I keep moving East, Bermuda will be my next residence.

Welcome to the DarkCISide. Another convert in the makingI had never been in a 126 before, and color me impressed! Nice door thunks, and totally quality materials. Definitely a bit more of a retro feel than the 124, but wow. I LOVED the seatbelt presenters in the SEC.. And the reclining & heater rear bench in the SEL. Very neat!
They are rare, quite rare. In 5-6 years of going to the yards in the Houston area pretty diligently, I saw a grand total of about 5 E420s and 400Es, and 1-2 "Sportline" pedestrian W124 sedans.I love the trips to the pick n pull. Such a fun afternoon digging around and just picking up what you want. I wish we had more V8s in the yards up in Seattle.
Bummer! This is a common problem, unfortunately. Some colors are NLA, and all are $$$ new. A good used one is generally fine, the trick is getting used ones with the center tab (screw cover) intact. Same clip is used on 123, 124, and 201 chassis which helps locate donors. There are cheap Chinese copies on eBay but I don't know how long they last.Eep. Drivers side sun visor clip just disintegrated!
Hello Guest !
We wanted to let you know about a new resource that is now available to all 500Eboard members. This is a comprehensive database of all US-market (and soon to include Canadian-market) 500E and E500 models delivered for the 1992 through 1994 model years.
Data for this resource has been compiled continuously since mid-2003, and much of this information is seeing the light of day for the very first time ever. This new resource will allow you to utilize 500Eboard research and resources to track specific cars, their sale history, documented modifications, and other information that has surfaced over the years.
We are also providing analytics about the cars' production. This means that if you are curious as to how many "Signal Red" cars were produced for the US market with a black interior, specifically in Model Year 1993, you can now easily find this information. You can also find aggregated information -- for example, how many "Black Pearl" cars were imported into the US over the three-year span.
You can always find and enjoy this resource by clicking here (bookmark the site for easy reference!), or by going to the “500Eboard Registry and VIN Database” sub-forum below. You can also find a VIN Database button at the top of your screen, for easy access.
We hope you enjoy this resource. A LOT of blood, sweat and tears over nearly 23 years have gone into its creation.
Cheers,
500Eboard Management
