Just-in-time :I stand corrected, there are setting on analog gauges. Adjustment is 4-12 on tachs, I adjusted lowest to highest level, no change. I tested the voltage to the tachs green wire: 5 volts @ 500 rpm, 5.4 @ 1000 rpm’s and up. Anybody have any idea! Tach’s and wiring worked fine on previous engines. Stator test with continuity “360 ohms” green and white wire, charging coil o.k., voltage regulator test o.k. Any ideas?
