93 Sl500 no start issue
Hello. I have an issue with my father's 93 SL500. I replaced wiring harness and changed the fuel filter. After the work was done i started the car with the rear part of the car raised to check for any fuel leaks. Car started with no problem at first try and run well. After few minutes i shut it down to put the wheel back and to lower it back to the ground. Unfortunately, the car does not start anymore. All it does is beeps 4 times when I turn the key into the start position. I checked all fuses, fuses in the overvoltage relay. It does exactly what the car in this video. I am located in the Harrisburg PA area, maybe you can recommend a mechanic who specializes with these cars. Preferably someone who could do diagnostics in my garage.
Here is the link to the video showing the issue,

The starter circuit goes battery -> ignition switch -> K38 alarm relay -> neutral safety switch -> starter solenoid. I'd have someone turn the key to the start position while someone checks for voltage at the neutral safety switch proceed from there.
