w126 electrical gremlins.
I've just got my w126 on the road again, and I have some problems. It's been sitting for around a year now.
Fuses are new, and none are blown; voltage regulator is new. Tach is jumpy, and insterment lights wont turn on. Wind Shield wipers are also slow (and useless) It just seems like there not enough voltage to run everything. I'm going to get the battery test/replaced here soon. What else could it be?

Check all grounds; there is a major grounding point immediately behind the instrument cluster, for example. Good battery is also necessary. Good belt on alternator, not slipping.

If your going to have the battery tested ask them how many volts you are getting on idle. Make sure your battery connection are clean and tight.

I have a 380se, W126 chasis, and am having similar issues with major dash functionality problems. Erratic tach, speedo jumping around at a dead stop, turn signal intermitant functionality, surging cruise control while it kicks in and out, all gauges bouncing around. I am think for this much to be going TU, there has got to be a ground problem.
Just how hard is it to get to that major ground point behind the dash? Are we talking complete dash extraction? Or pull a few screws and viola? Many similar symptoms Thanks. |

relays also
I found pulling and reseating some of the relays in the fuse box also helped some electrical gremlins.
