Have a 2017 310SL It’s a tier 3. Has around 1500hrs on it. The other day my operator called me to inform me the hand throttle quit working and would not rev up the motor. But the foot throttle was working properly. The throttle ended up working intermittently for the rest of the day. He managed to finish the day and floated it back to the shop. When he got back I unloaded it to put it in the shop for the night. It was late and decided to look at in the morning.
In the morning I started it up and a code came on right away. High voltage. It was producing around 17-18 volts. So I had the alternator rebuilt. Throttle was still the same. So I replaced the hand dial switch thinking the high voltage damage it. It did not fixed the problem. Hand throttle still worked intermittent.
Any ideas where to look? Could the voltage have damaged the ECM?
I have a 2018 310SL. Basically identical machines. Could I swap ECM to see if that is the problem.
