Re: Beta Marine BD722 Tach kicks in after I enable extractor fan!
thanks Brian - I dont think it is a wiring problem as in idle mode (or low revs) the tach works properly!
Would this behaviour evidence itself if I have the alternator belt too tight? I dont have the tension instrument but looks and feels ok with less than an inch of slack?
You didn't originally say the tach works at idle. As it is an electric tach it has to be wiring - possibly corrosion of a connector.
