    Voltage Regulator/Rectifier Upgrade = Mosfet

    My charging system is running 15.2 volts, sometimes 15.5v, which is still in spec but I have concerns.
    Yes it has a 1 year old NOS R/R on it and that didn't change anything.

    1) My AGM battery has started failing, I believe from the high charge rate since they don't like anything over 14.5 volts. It's the MotoBatt and just 2 years old now. Not a problem since another one will be one the way tomorrow.

    2) I'm about to go over to the Ignitech ignition control unit which should only run in the 8-14 volt range, although they say it'll handle up to 16 but they don't advise that.

    I've been researching the Mosfet R/R's for the past week and that seems like the way to go since they all seem to have a stable voltage output in the mid 14's and run cooler as well.
    But, they are all a 5 wire design. 3 AC inputs, 1 Batt+ DC output and 1 Ground wire. The CM uses a 6 wire design that adds a Black switched power voltage sense lead. I can't seem to find an answer to the questions: Will the Mosfet design work properly without that lead? Will it work properly on the CM?
    The answers are?????????

    I believe the function of the black wire is accounted for within the Mofset unit. If so it should work just fine without it.

    Re: Mosfet Regulator/Rectifiers

    That's my thought and Steve had the same one. I'll visit my friendly boneyard today and see what he has to experiment with.
    New battery shipping today.

    Re: Mosfet Regulator/Rectifiers

    Read thru this http://www.rc51forums.com/forums/showthread.php?t=6540 and it pretty much confirms I can successfully do this. Just not connect the Black wire.
    Found this kit http://www.ebay.com/itm/YAMAHA-SHINDENG ... d6&vxp=mtr
    that is the latest version of the unit w/connector plugs.
    I've gone thru the entire wiring harness and connections to insure I don't have some weird voltage problem. Only voltage drop is at the Black at the VR connection of .05v

    6-7-2016 Update: Sparckmoto is offering the regulator for $95 including the connectors http://sparckmoto.com/Products

    Re: Mosfet Regulator/Rectifiers

    New RR due today. So time to do the prelim tests of a stock RR with a new battery.
    Started with the battery on a Batt Tender until it showed charged, let it sit for 1/2 hour to stabilize. 12.81V Did a 30 second discharge of running lights, no head light, 12.31V
    Started and running at 1200 rpm cold 14.8V
    Rode @5 miles in town charging at 14.1 to 15.5V
    Rode @5 miles freeway speed charging 13.5 to 15.3
    Idle when done with headlight on 12.9 to 13.8
    Battery voltage after parked 13.5V
    15 sec load w/o headlight 13.0V
    1 hour parked 13.1V

    Regulator got here and I've got the harness made so I can install tomorrow. I noticed that the wires coming out of the stator are 16 gauge but the RR wires are 18 gauge. I'm using 16 gauge going into the Mosfet RR.

    Re: Mosfet Regulator/Rectifiers

    New RR installed and roadtested. I'm a happy camper
    Battery charged and tested the same as previously posted, same results
    RED is the OEM regulator GREEN is the Mosfet regulator FH020AA
    Started and running at 1200 rpm cold 14.8V....14.25V
    Rode @5 miles in town charging at 14.1 to 15.5V....13.7V to 14.1V
    Rode @5 miles freeway speed charging 13.5 to 15.3....13.7V to 14.1V
    Idle when done with headlight on 12.9 to 13.8....14.0V
    Battery voltage after parked 13.5V.... 13.2V
    15 sec load w/o headlight 13.0V....12.8V
    1 hour parked 13.1V....12.57V
    These results say this is a good upgrade for stabile charge voltages and eliminating the excessively high charge rate found on the OEM regulator. Now to get it permanently mounted. The hole spacing is larger so I have to figure that out.

    Given the data you've provided about the performance of the Mosfet regulator, it seems that this mod would make adding a lithium iron phosphate battery from Shorai more feasible/workable. I've heard from other forum members that the stock charging system is essentially "too much" for these batteries and prone to charging the battery in excess of its needs. this causes damage over time

    according to Shorai themselves, "Shorai Batteries require a charging system output of 13.1 Volts or higher at idle, and must not exceed 15.2 volts at maximum output."
    Faster, faster, until the thrill of speed overcomes the fear of death!
