Now that I have my jst connectors in place for hall sensor wires I am able to get some voltage readings on the wires. I was in luck today when I powered up the bike on the stand with my voltmeter in hand as the motor was acting up so this was the ideal chance to see what was going on.
First I tested Black wire to Red wire and it reads 4.39 V so I think this is ok. I have read its supposed to be 5 volts but I am guessing this reading of 4.39 is close enough.
Second I tested between black and yelo wires while slowly spinning the motor backwards and got a voltage change between .03v and 4.89v so this is good if I understand things right.
Third I tested between black and green and it was .03 and 5.06 so this also is good.
Fourth I tested between black and blue and I got a steady reading of 5.06 and no drop in voltage when I spun the wheel slowly in reverse as I did with the other wires. So I am pretty sure it is the blue wire or its hall sensor that is the problem.
OK...... so feeling like I am narrowing down the search and will pull the stator from the mag bowl this week end and hope to replace the hall sensor and its wire for the blue duties.However I do have a few questions when looking at the inside of my motor as shown in the attachment here.
1....What is the little yelo thing that I have circled in purple that is sitting on or in the green plastic thing that is holding the hall wires and hall legs?
2.....What is this green thing? I saw one photo on line of hall sensors in a different motor and with its wires & it just looked like the legs of the halls were soldered right to the wires going to the controller with no sign of this green thing sitting in the stator area. Is this green piece of plastic kind of like a circuit board? I am assuming so and not sure if I should try to bypass this green thing and just go with a straight connection from the hall legs to the wire and then to the controller?
..........any tips appreciated.........thanks Wayne
