Good to see inside the lil devil...

My old ovr MB # 126 5404745 likely 4/82
has only 4 prongs & a plastic

30
31
87
87a/15

There is a rattle intermiitant in it

Replaced w new one made inHungary last night

not sure if its good or not but w 196K on it it might be getting old?

If its just a fuse as has been said why would it cause all those problems?

Anyway got a new one & hope its a good one...

So, on a 300D (w123) where exactly is this lil' bugger located?

OVP WOW!! Little **** sure does alot..
 

I can't get over how many people and how many headaches this little device causes. I hate to beat a dead horse but....

How does all this information apply to a Diesel? 87 300D - I found my fuse blown, replaced the fuse but can't really see a difference. My Tach and CC are still inop.

All those that sent help via this forum! Wow.. I'm impressed and thank you very, very much. This is my first Benz and as a seasoned mechanic but having never worked on a merc I must admit that I'm not only impressed with the so called over-engineering but I'm absolutely in love with these cars from a mechanics point of view. There's few parts that can't be fixed with a little know how and some help from what seems to be a very enthusiastic brotherhood.

Stecebfl,


Thanks for the extremely informative post on the early lambda controls, closed loop operation, etc.. Good stuff, man!
