Voltage problems, cutting out when hot

You need to label each photo to show what it represents. The 15.71 is obviously running charging and that is too much You sure the extra ballast is wire correctly?

I did label under each picture, I can be more specific if needed.

If you are still running an ammeter, where are the fans pulling their main power?

When I remove the power to the fans, there is no change in voltage just as when they are not running voltage readings are the same.

Fan main power is fed at the starter relay, I thought about rerouting to the lug on the alternator instead of the starter relay.

I wired the fans as was laid out in another post on adding Ford Contour dual fans with dual relays and DD controller.
