Have had problem last 2 years with port side tach on my Albemarle 280 Express powered by twin tamd41-p's. Upper station and lower station gauges are VDO. Port side tach wont work until throttle is revved up past 2500 rpm or so then it "breaks free" and works rest of day. I replaced port side alternator but nothing changed. Connections all look good. Lower station tach is parralled (I assume) to upper station tach and same problem with upper station. I'm at a point where i just want to replace all 4 tachs but not sure what I can or can't use. I dont want to break the bank but I know 4 new tachs won't be cheap. Also, are they hard to set up once installed, ie calibrate? Any advice from the Volvo Diesel gear heads out there?
