Hello, my SL 600 V12 is 14 years old. I only ride a little bit in the summer. That’s why it only ran 12,000 km and is visually and technically there like factory new, also the whole engine. The only problem is because of the long service life over winter (6 months) the two batteries, which I have to charge again and again and have also renewed twice. Recently I charged both again, then removed the chargers and during the voltage test with a Mu ltimeters had both batteries full charge. Problem I can not start the engine. If I turn the ignition key on start, there is only a quiet buzz in the engine compartment and the starter does not move. But on the engine incl. starter everything is in best order and I am sure that the starter only gets no power. With digital technology I unfortunately have problems. Does anyone have an idea? Friendly greetings Jink
