2006 Charging System?

[XJRGUY]

How ghetto is the fact that you can't even rely on the manufacturer's guide for accurate information.

It's not a big deal heated or not, but now I am beginning to wonder what other inaccuracies are out there in regards to the technical spec of this motorcycle.

Mistakes in service manuals are common. I've worked in the auto industry for 25 years and they abound (all manufactures). Motorcycle are no different. There are just too many hands touching the tech stuff to have 100% consistency. Severice technicians just learn to live with this reality. Yamaha doesn't seem to be any worse than others in this regard.

No matter what the Yahmaha guide states, a two-wire O2 sensor does not use a heating element. On a 2-wire O2 sensor one wire is for ground and the other is the signal wire to the ECM. A 3-wire O2 sensor use 1 for ground, 1 is 12 volts (heat element) and the last is for the ECM signal wire. A 4-wire O2 sensor uses 1 12v and a ground for the heater, and an extra ground an signal wire to the ECM.

Makes pretty good sense, except why waste a wire for ground when the O2 sensor is screwed into a perfectly good chassis ground. Then the second wire could be the heater wire.

Electronics are always better served with a dependable ground back to negative instead of depending on chassis (floating) ground and the higher potential for ground loops that could create noise on the line.

That's one of the reasons why the DynoJet folks recommend you ground back to the neg terminal of the battery instead of to chassis.
