When connecting a tachometer separate the two green leads and hook these to your tachometer. For a charging system connect the two remaining yellows to a rectifier, two yellows, which will then allow DC power off the red and black leads from the rectifier. If your rectifier only has two yellows and one red then the red is now the power, and the rectifier is self grounding. This system does not need a battery if the circuit is drawing a constant 1 amp Wiring using a rectifier but not battery - requires 1 amp consumer.
