That'd always be my preference too!I have seen a couple listings for them when I was researching my possible idea but but if he was making them I would want to support a community member before the outside world.

Hey Ryan, I am NOT very well versed on electrical, but am curious if what you made here is the same idea as something I added to my GX460? When I moved to an AGM on the GX I came across this voltage booster and it seems to be doing it's job, no issues over the last year or two.Posted these photos over in @COS80 thread regarding the charge circuit. He'd inquired about using a diode in place of the 7.5A charge fuse to increase the alternator output to more like 14.0-14.5VDC to make AGM batteries happy. In many modern cars, the charge fuse is in the sense wire circuit of the alternator, and adding the diode in the proper orientation increases the alternator output a bit, as the diode has a voltage drop across it. That in turn lowers the voltage on the sense wire circuit, and the alternator charges at a bit higher rate to compensate. This diode trick doesn't work on the 7.5 charge fuse of an 80 series, as that fuse is on the charge warning lamp circuit, not the sense wire. I whipped up a little harness to test a theory without cutting any wires. Using the appropriate connectors and an inline use holder, I made a harness that plugs into the alternator and into the factory harness and adds a diode to that sense wire.
THIS IS AN EXPERIMENT and I'm not recommending it as a permanent installation to anyone. Thats my disclaimer. Anyway, on with some pics.

Yes, same exact idea. The little device you linked just has a one or two diode option depending on the switch position. Mine is simply a single diode inline to the sense wire of the alternator. The later models like your GX actually run that sense wire through the fuse box, so you can easily add a plug and play module like that. On the older 80 series, that fuse only runs the charge warning lamp circuit, so adding a diode won't change the alternators sensed voltage and cause it to increase the charge voltage.Hey Ryan, I am NOT very well versed on electrical, but am curious if what you made here is the same idea as something I added to my GX460?
