It should have electronic ignition.
The point gap for a 1975 Mercedes 450SL should be set to approximately 0.016 inches (0.4 mm). This gap is critical for proper ignition timing and engine performance. Always consult the vehicle's service manual for specific guidelines and adjustments to ensure optimal operation. Regular maintenance of the ignition system, including checking the point gap, is essential for the longevity of the vehicle.

1975 for the HEI (High Energy Ignition) system (no more ignition points)
I have a 1975 450Sl and the ICU is located on the driver's side, in the front wheel well on the fender just below the coil. It's a cast aluminum looking box. Otherwise, running from your distributor is a covered wire that holds two internal wires (I think two)... trace that back as it will lead you to your ICU. Tim
The 1975 Ford F150 4.9 L ( 300 cubic inch ) straight 6 has electronic ignition , it doesn't have points

To set the points gap on a 1975 Yamaha YZ 80, you'll want to adjust the ignition points to a gap of approximately 0. points to ensure proper ignition timing. This can typically be done by removing the flywheel and using a feeler gauge to measure the gap as you rotate the engine to the correct timing mark. Always refer to the specific service manual for exact specifications and procedures for your model.
As far as I can tell , yes ( in 1974 , depending on size of engine , there were either points or electronic ignition )
To jumpstart a 1975 Mercedes 450SL, connect the positive (red) cable to the positive terminal of the dead battery and the other end to the positive terminal of the working battery. Then, connect the negative (black) cable to the negative terminal of the working battery and attach the other end to a grounded metal surface on the engine block or chassis of the 450SL, away from the battery. This setup helps prevent sparks near the dead battery. Finally, start the working vehicle, then the Mercedes.
If the bike has a "points" ignition system, check the starter circuit to see if it has an "ignition resistor bypass" to give a hotter spark when starting. This was pretty common on cars of that era. My 1975 Triumph motorcycle is set up with points and a bypass. Check the service manual (or do a visual by tracing wires backwards from the points) to see if the bike has a ballast resistor -- jump it to see if it will run and, if so, replace it.
