Apologies for the Engrish in the thread title.
I think I might have some charging voltage issues. Bikes is an Aprilia Falco with an eastern beaver wiring kit connecting the FH008 Mosfet directly to the battery. Charing voltage is a nice 14.3v or so at the battery when lights and all the other stuff is off. With low beam it drops to 13.9. High beam gives me another .5v drop. Same thing with rear brake lights or fans. Even see a drop with indicators on. This is irrespective of RPM (checked at idle to 4000 rpm or so). When ancillaries it just doesn't get to 14V anymore. Also the dashboard light and parking bulb briefly flicker when the brake lightis activated.
I checked the alternator resistance at the white barrel connector and the connector at the regulator. Resistance at every terminal is withing spec (below 1ohm) and there is no visibile damage to the terminals or connectors or what so ever. They look perfectly fine with no loose wiring. Charging voltage is above 60acv at 4000 rpm. I don't have any blown fuses or anything like that. Bike just had a new Yuasa YTX14BS battery and it fires up perfectly with no hesitation.
Before these issues started with the current wiring/FH008 regulator setup always gave me around 14.5v no matter what was on or not. So it has worked properly with the Mosfet regulator before this problem started. I am thinking the regulator might be going south, but I haven't seen a lot of Mosfet FH008 failures.
