Field instantly and always at 100%


  • I have just installed my WS500 and it seems the field is always at 100%?

    Even when the regulator is in the "off state"

    As soon as the ignition triggers the regulator to be on I can hear the alternator load and its at full output. 

    Any ideas? Would incorrect P type and N type configuration cause this?



  • Does the WS500 field get driven to 100% ?

    If not, try removing the field wire.  Does the alt. still go to 100%?

    If so, you may have some wiring left over from the internal regulator causing it

    If not, then that confirms the power is coming from the WS500 field wire


  • @Rick

     When the regulator field wire is removed it doesnt power the alternator. 

    When the regulator ign feed it off it doesnt have the issue. 

    There is no regulator on the alternator two wires going to the brushes. 

    The odd thing I found is there is always continuity between ground / field / alternator +


  • Is your alternator P or N?

    Knowing this, I can tell what to test.

    Also posting some pictures from your wiring can be helpfull to give advice.


  • @Ben 

    Currently one side of the field goes to B+ alternator positive. 

    The other goes to the wakespeed pin 7 "wakespeed field" blue wire.


  • Would this issue happen if the field is wrong? 


  • You can test the field output with by connecting a testlight.

    Disconnect the blue from alternator, and connect a light to this blue wire.

    Other side testligt to positive( with N wiring harness)

    After apply power to the brown wire the light start glowing slowly after 1 minute( depend on settings).

     

    Tell me what the light shows with this test.


  • You can repeat this test, with testlight connected to blue and negative.

    This 2 test will show or you use the correct cable harness.

    Take also a ohm reading from,

    Brush 1, to negative, positive, frame alternator, rotor shaft.

    Same for brush 2.

    This 8 ohm readings tells or the brushes are connected correctly.  All readings should be infinity!!


  • @Ryan If you are still troubleshooting, the probelm is rarely the WS500 and often a wiring issue.  Having the wrong harness likely would not cause this isssue, but to test it is pretty straight forward.  With a good multimeter set to ohms resistance

    1. connect red to black lead and measure how close to zer it reads and use this value as your test zero
    2. connect black lead to case ground
    3. connect red to negative brush wire.  It should read very near zero
    4. connect your red lead to the other brush wire that is connected to your field.
    5. It has to pass through the commutator and rotor windings, then back through the other brush to ground so, depending on the number of rotor windings you should read a resistance of less than 10 ohms, and sometimes very close to zero

    When you have confirmed your polarity you can continue troubleshooting.  Some ideas to try.

    • Remove the harness from the WS500.  Does it still go to 100%?  If so, and it does not go 100% when field is disconnected, its a wiring short in the cable or connector.
    • Remove all "panel" wires 1,2,3
    • Verify polarity on wires 5 and 6
    • Remove wire 8 , stator
    • verify polarity of wires 10 and 11
    • verify wires 12 and 13 are wired across the shunt
    • Now you have bare bones installation and if no wiring issues were found, try testing again.
    • If output goes to 100% with field wire 7 connected and remains at zero if removed, it is possible you may have a bad regulator.

  • @Rick Thanks.

    Will try this.

    I was testing this morning and it seems I am getting 19 Ohms between the two field wires which seems fairly high.


  • Field winding is fine. Showing 6.9Ohms now. It was a problem with the multimeter. 

    The cable numbers you say dont seem to match what I have on my plug? I have the 1.0 Board 2018. Perhaps the plugs changed pinouts? 

    Im using the attached pinout to wire the ws500 harness.




  • Any insight on this old board? 

    I have configured it on my bench with the barebones wires attached as per ricks suggestion. 

    Ignition feed gets power the bulb turns on at max brightness. 

    I wired the plug as per the image above. 

    My question now is did somthing change from the V1 board? Maybe pinouts changed?


  • This seems like a pre-release board and we dont have any experience with it.  You're best to contact Al at Wakespeed

    al@wakespeed.com 

     


  • @Ryan I installed many V1 board. Nothing changed on pin layout with newer versions.

    Did you checked that your harness is a Ntype harness?

    If you have a Nharness and your test light is between the blue and red wire, then there is a problem with your board.

    At the time the light is on, what is the field value in AST data string?

    Readout AST with app or laptop.
