My trim up function stopped working earlier this summer. But if I use the overide switch for tilting its work fine, trim down works without problem. I have a Volvo Penta 4.3 Gi with DP-S drive with trim limit. When a press trim up there is a yellow lamp lightning at the trim limit but nothing happens, but when pressing both trim up and the override switch (a red lamp lightning at trim limit) the drive comes up. Is there something wrong with the trim limit and I need to replace the hole unit?
