TACH me back to simpler times.
Calling all mechanics. I have two Perkins 6 354 turbos and the gauges were getting pretty crusty so I changed them out for new Faria's and because some were not working anyway. Problems: alternator driven tachs just sit there and look at me, nothing. Alternators tested about .5 amps. Got new Napa oil sending units but gauges peg out to 80 when engaged and stay there when started. Back to 0 when key is off. Any ideas??? Mahalo Kevin
