Hello to the forum, I’m relative layman and have a problem with a stacker where the battery is not charged. I changed the alternator, the control (is external) and the battery. Unfortunately, the battery light is still lit and the battery is not charged either. The alternator and the controller are equal to the old parts and the occupation of the cables (at least the color coding) the plug is the same. If someone has a tip as I can find the error or w Since a forklift can unfortunately not simply be driven into the workshop I would be happy about every tip. Would it be possible, for example, that the polarity on the controller is wrong? Or can a simple “cable break” be the cause. Since the forklift is already older, it can not be due to any “electronics” – since none is available. I am happy about a feedback.
