I got my alternator delete working this past weekend. I had some issues getting the alternator to turn off and stay off. So, I ended up making a simple little circuit with a dc-dc converter to trick the voltage regulator on the alternator to thinking the battery's voltage is higher than it really is. That did the job quite nicely. Here is a schematic of the circuit.





It all taps in via a fuse that goes to the sense wire on the alternator. So, I 3d printed a fuse body, and cut some metal tabs to put in it. A bit of super glue and solder and it works great for a plug in modification. There is only one other connection necessary and that is a wire to ground.

3d printed fuse tap.





The whole circuit.





It fits nicely in the fuse box under the hood. Yeah, this means I have to open the hood to turn the alternator on if necessary. That will change.
