I'm sure there's a post somewhere but I can't find anything . (Google is not my friend either ) I am getting a one long beep warning it's not continuous and it's sometimes random . Sometimes when I'm idling sometimes when I'm running but it's driving me nuts. It last for around 5 seconds . thanks for any help .
Couple things, there's a forum dedicated to the 3L and you may find more info (be sure to include your serial number). There's a great FAQ at the top of the 2.5L & 3L forums which is better than Google for your Optimax. Lastly, here are a few topics from the FAQ you may find helpful:
Recommended Annual Maintenance or Winterization for Optimax Engines
Compressor STRAINER Cleaning
Proper Warmup and Cold Water Operation
Engine Shutdown Precautions after a HARD RUN (Especially in cold water)
