I have short in my 1992 300 se

if you have installed new components to your car, make sure you are putting together the right polarity of each wiring which is positive to positive and negative to negative from the new component to the wiring harness of your car,
if you are testing for a short circuit , the reading is zero voltage dc
but if open circuit it is infinite when you are using a voltage meter. see manual of your vehicle to see the circuit diagram. then follow the positive sign( +) and that of the negative sign (-). when testing.
always set your meter voltage higher than the voltage produced by your vehicle which is 12vdc standard source.
when you turn on your radio to the best station but still you are hearing some interference or annoying sounds or noise, then something wrong with your connections,
double check the connectors you have connected like the RCA jacks ,auxiliary jacks, try to take them off first then try listening if it is clear sound coming from your radio station.
how did you know you have short circuit in your car??? ehat is your clue??? let me know. and what are the experiences you have encountered to determine exactly what it is

Installing radio in 85 mercedes-benz

there is no amplifier. you just need to find the memory wire that is hot all the time and the 2 wires that are hot with the key on. One is for radio operation and the other is for antenna operation. The speaker power is supplied through the fader switch in the center console and the switch is powered by the head unit. Just hook up your circuit 30 and your 2 circuit 15 with a ground and run you speaker wires to the head unit or if you are installing an amp from the wires from the fader switch. That switch can be popped out with a flat blade screw driver, Hopefully i have been helpful

I need a 1992 mercedes 400 se sparkplug wiring diagram

most older mercedes benz firing orders are written on valve cover. I beleive it will tell you on one of the rear intake manifold runners. the way a benz engine cylinders are marked they read-1 2 3 4 on the l(passanger side) and 5 6 7 8 on the r(drivers side) unstead of 1 3 5 7 and 2 4 6 8. maybe this will help you good luck getting the plug sires back into the plastic troughs.
