FYI thing on Vicki with the Equus tach. At times my Equus tach would have the needle swing wildly all over the place. This is using the plug fired impulse lead. Some days it would happen other days it would not. I did all the tricks with the sensor on the plug and still the same situation. I looked at the Equus installation guide and seen a BIG issue is the ground itself. So I decided to use the ultimate ground itself,the ground wire right to the negative pole of the battery. AND PRESTO no more tach needle issues. On my sled powered HD cart also using the plug fired Equus I did not have any issues BUT either I was more careful with the grounding OR the the CDI ignition of the sled engine gives a stronger pulse signal for the plug sensor.
