the regulator will “mis-read” the battery and overcompensate in terms of charging voltage. Here is the same circuit with an oxidized or worn-out contact in the switch causing a .75 volt drop between battery and regulator on the signal wire: The rectifier/Regulator appears to be over charging， like any electrical device，。
or any weak point occurs (this can commonly occur if the contacts in the main ignition switch have any kind of wear on them)， if corrosion， here’s a diagram showing a full-wave Rectifier/Regulator with a signal wire operating properly: The battery in this circuit is charging correctly. However， and a brown wire. The brown wire is the signal input from the battery. The Ricks piece features only 4 wires; the position where the OE brown wire was is vacant. This is because the Ricks part is capable of regulating through the DC wires without the sensor input. Why is this advantageous? Because a regulator， the same circuit with no connection at all (as if the signal wire was cut): The regulator no longer has input from the signal wire and no way to properly regulate the battery. This results in an extreme overcharge. The same rec/reg can produce 3 different results depending on the integrity of the signal circuit. And THAT is why Ricks eliminates the the external signal wire = problem prevented! ， there are 5 wires going to the OE part: 2 yellow wires (AC inputs)， black/yellow (DC “-“ output)， and any voltage drop between the battery and regulator on a signal wire can result in a “false positive” reading of an overcharge at the battery. To illustrate， is only as good as the information you put into it， however nothing is wrong with the component itself. It is simply acting on inaccurate input. And finally， guys were going to get a little technical in this blog post! Weve had so many questions about a missing signal wire that we asked our tech guru Sean for an exact answer. This is what he had to say. Many Rick’s Motorsport Electrics Rectifier/Regulators eliminate what is commonly referred to as a “signal wire” on original equipment (OE) pieces. For example， white/red (DC “+” output)， a poor contact， on a 1981 Kawasaki KZ440， Ok。
