w123 ignition tumbler electronics
So, I've read plenty on failures of the tumbler to turn. Like it was mechanically fucked.
Today I was trying to start my car and it seems like the battery was dead. Ok, I guess I left the headlights on. There's supposed to be a warning buzzer for that shit. That buzzer and all the dash run on fuse #1.
Ok, so i put in a new battery, turn the key and the dashboard light are on. Starter wont crank.
Next, jumper cables to a prius(huge power). Now turn the key and dash lights aren't on. Full battery, fiddled with the #1 fuse.
Has anyone known of the key/switch to get electronically fucked up?
I will keep working on the fuse too.
Maybe the tumbler. I had a similar fiasco. I replaced the positive terminal connection on the positive battery lead with an aftermarket one from autozone. Mine had been eaten away. (I had a brand new battery). I tried to start the car after, and I got some funky symptoms. Wouldn’t start, lights, blah blah blah. I felt like an ass when I had to towed to my mechanic and all he did was tighten the new terminal connection to the lead on the battery post. Everything was back to normal. I suggest checking things under the hood to make sure the lead is tight and you are getting 12v into the cabin.
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?
Check the clamps AT THE BATTERY. If that shit gets invisible corrosion it won't start at all.

Ok, so it's like the starter isint even resetting or whatever. IDK, you know how you turn the key to the 'start' position and there is some physical resistance against you.
Now there is none at all. And the key just turns freely.
hold on, hold on.
I am feeling super deja vu. I feel exactly as if this has happened here before and I was asking the exact same shit here at std. WTF, this is a strong feeling. Maybe it is just need to rest for a bit. We'll see.
So to sum it up...
The problem was in fact mechanical in nature. Inside that tumble/switch somewhere. The harness is intact and all of those electric features can be run with a jumper wire. Just trying to track down a used key/tumbler/thingy

I was super lucky. I had met this guy a while ago at lowes.
He come up to me and was all like hey man I dig these cars and have got some junk ones, et cet.
Wrote down his phone #.
So I called him up yesterday and was like hey man 'im in a pickle...'
He was like $20, go out to my house and pull it off this front half of a w123/300d.
Totally stoked, back in business. My ignition had always been rough to turn and this one is way better.
From that dieselgiant how to page you'll see he says set the key in #2 position in order to pull out the wiring harness.
But my busted ignition had no way to turn to the #2 position at the back end, even though the key end would turn through the whole range.
The replacement had same part # and manufacturer but had a slightly different rear side. Hooked up just fine and works better than the old one ever did.
I wonder which part is next to break.
I have had that happen with my 83 300sd. Something inside the tumbler gave out and was unable to start the car. Had to jump the wiring on that connector block to get into a safe area to be worked on. I ended up splicing a push button switch into the harness to be able to start the car.
This car has thrown me a few curve balls but its nothing some good ol engineering couldn't fix. Lol. I lost the glow plug controller about 2 months before the key tumbler lost its start position. A starter solenoid and a toggle switch fixed the glow plug relay problem.
By chance is that guy you got that part from in the southern Indiana area. In all reality I'm roughly an hour east of where you are larsalan.
His home was actually to the west of where I'm at. Somewhere down a hick road in whitehall I believe. There were like 10 cars out there but more bmw than benz.
