I have a little more homework and Info for you guys. Over the years we all have had issues with setting and adjusting the boom speeds, either to fast or to slow, the function can feel rough or jerky or even black and white. Some have tried to repeatedly adjust the boom speeds with the Teleteach buttons or battery to no good result. If you need to constantly teach the remote you generally have a remote issue, other than oil temp variance the settings should stay relatively the same, week to week. But there is another option you can easily look at for these types of symptoms. The joystick is communicating to the coil on the boom valve, the coils can wear out, as they draw more Amps the range of motion changes, thus the need to adjust from time to time. The plunger spool’s that the coil’s drive can also get sticky or gummed up over time. The images below will show you how to remove and clean the spools, test the coils, and look for issues. The coils are the same from valve to valve, so they can be moved around. BUT BEWARE, on units equipped with EBC this is not advisable, the computer is set to work with the coil and valve matched, adjustments to the EBC programming might need to be reset if coils are changed or moved around. The leading problem we have with Mother Boards on 24 V systems is over Amping the fuse. If an outrigger or Boom coil is bad it can draw high amps and blow the fuse. DO NOT PUT IN A BIGGER FUSE, RUN THE FUNCTION MANUALY AND FIX THE ISSUE. Other issues that can give you problems with these spools and other components on the unit are cheap oil, dirty oil, water in the oil, and high “TAN” numbers. These all lead to corrosion and sticky components all over the unit. Phantom issues that come and go are usually related to the oil and its condition. Do oil sample testing to ensure the condition of your oil. Oil that has water in it looks milky ONLY after it has become saturated with to much water, clear oil in the sight gauge can still have to much water in it. The only way to know for sure is to have it tested. I hope this helps and brings out even more questions, please feel free to ask online or call PM CSG at 1-800-890-0269, or myself at 360-600-5695, or reach me by email at woodsa@putzam. As always, be safe and keep the rubber side down. Travelteck
