Error E71

hello, error e71 has appeared, which indicates either an increased current in low circuits, or a short circuit in them. I can't figure out what the problem is. after switching on, when trying to move, everything turns off and you have to restart the loader. after some attempts, he still agrees to go. immediately, on the forum, on other atlet loaders, with the same error, they offered to put a resistor between
the key relays are k5 and k3 (in my case k3 and k6), as well as the replacement of the hydraulic motor sensor bearing helped someone, but I have this error even when the hydraulics are not involved. the battery is brand new and charged, which eliminates the occurrence of errors due to low battery charge. please help with this problem

Hi error code E71 is height- low voltage that could be anything from the computer to any wire harness, but if you try to drive and loose power on the display first thing to check is the battery must have 48v or no less then 42volts when is driving put your multimeter on the battery cables and look at the meter what is the voltage! try to press on the accele, very slow look at the meter shouldn't go lower then 42 volts, the error code will stays on until is clear of throught atlet service manual, but the unit should work, what the model and serial will help? My guess is your battey!

If you have a box with 4 red leds you don,t need the resistor, the box with 12 red leds needs the resistor.
sometimes inside the box there is a small relais that needs to be changed, you can check this by gently tapping on top of the box while slowly lifting, if it falls off then the relais is wornout.
