Help. I am a newbie here and thought someone could help me. Years ago I bought the Allegra M 816 engine monitor. I have it installed (and it's fellow instrument the Fuel Flow Gauge) and everything but the Tach works (6 cylinder on a Continental IO-550). I have heard that many RVs were running around with them and I need to speak to someone as the company is out of business. Thanks, dan [email protected]
