  1. W124 Duty Cycle

    W124 E,CE,D,TD Class
    1) the ac was off. how i adjusted the EHA without pressure gauge(might get one soon): was running the engine at 2500 rpm, if current was going into negatives, adjusting counter-clockwise(1/8 of a turn at a time) or opposite way if current was going into positive at 2500 rpm. also: if...

    W124 E,CE,D,TD Class
    1)The pic of the economy gauge is at the idle rpm(around 650 rpm i believe). 2)The leads are reversed on purpose, so i get 70% with key in on position, not 30%(because MB uses the reverse way duty). i get around 97 HZ on 2 and 3 with this meter, which i believe is ok. Reverse gives me 30% duty...

    So, it is very much of an intermittent sort of problem, sometime it is like this(on the video), sometimes it is alright, and what i have noticed yesterday, the light in the car(dashboard and the other bulbs flicker, and turning on or off the any electrical stuff in the car causes rpms go down...

    1) #1 is connected, it has the wire, just not seen on the pic, it is the same wire as marked on the pic, according to my previous testings with the meter. I have played with it today a little, enriched fuel pressure on eha(by 1/4 of a turn clockwise) and lowered the readings on...

    The fuel was rebuilt recently, by me, and the diaphragm is in perfect condition. The accelerator cable is new(febi) Never measured the fuel pressure, don't have any pressure gauges.

    How do determine if they have resistor in it? i tried to find any information on that and didn't. I just measured the resistance of my spark plugs - 4.6 Kohms, is that what non-resistor once should have...

    I recorded 2 videos to better explain everything.
  9. W124 Duty Cycle

    W124 E,CE,D,TD Class
    I forgot to mention, if measuring HZ, between port 2 and 3 i get way over 100hz, didn't really measure that a lot, but usually get somewhere 130-150hz(no clue what that means). I tried to measure between 1 and 3 after couple weeks of trying everything to figure out why im not getting the...

    So, here is the problem with my 1989 300e: (I am not mechanic, and never had any experience fixing any cars, before bought this one in Feb. this year) When I am trying to adjust the duty cycle, and connect my multimeter( tried 3 dif. meters) to x11 port with the key in the ignition(on position)...
