I found a SunPro CP 7678 at a local AutoZone (I think) for about $100. The CP7678 includes: Dwell (4,5,6, & 8 Cylinders) Volts Duty Cycle Ohms Tach (4,5,6, and 8) It does *not* have the capability to measure milli-voltage accurately below about 100 mv. ---------------------------- Allan Morris Phoenix, Arizona allanm@primenet.com ----1988---90Q--------------
