Common Valeo Alternator Wiring Diagram

We are looking this Valeo alternator wiring diagram up from time to time as replacement units do not always come with these terminals identified. There are many units that run a similar diagram to this one. Some have the D+ spade terminal in the regulator and some use the post. 

*This is a basic wiring guide and will not cover every application or scenario. Always use caution when modifying a system. While Smith Co Electric deems this information accurate, we are not liable for problems arising from use of this information.

    B+ is Battery Positive, B- is Ground, W is a tach signal (optional), and D+ is a key switched 12V positive that may run through a no charge indicator light.
