I've done quite a bit of research on this and am looking for confirmation.
Below is the schematic for the Stock Safety Relay I lifted from 650rider.com. The relay coil is feed from the Stock alternator's 6V yellow wire. Once the motor is running and the headlamp is on the headlamp relay coil is kept closed by the headlamp feed via the resistor. This ensures that the headlamp stays on in case the alternator power dips.
Below is my understanding of how a Headlamp Relay should be connected in a custom application. Since I'll be using a PMA, which does not have a 6V lead, the relay coil needs to be feed by one of the PMA's wires that feeds the R&R. Since this voltage is in excess of 12 volts feeding the relay coil through the headlamp power via a resistor is not needed.
Makes sense? Or am I completely out to lunch.
