When I originally got this boat & set up the trim indicator worked, now it doesn't what is the logical sequence of trouble shooting this? I bought the OEM manual but it doesn't have any info on the digital gages can any one help, Ray or Rodbolt, please? All other indications appear to be working, best I can tell. I can't really see the dip switches mentioned in other posts, unless they are under a flush rubber boot which I haven't yet peeled off!
