Planetary Gear & 19 Tooth Freewheel Sprocket Kit w/ 12mm Star Shaftġ9 Tooth Freewheel Sprocket with Star Shaft AdapterĢ4 Volt 22 Amp Controller for IZIP Via Rapido Electric Bicycle (9 Connectors)Ģ4 Volt 35 Amp Controller for IZIP & EZIP Electric Bicycle Irrespective of that you have enlightened me on a number of points.Izip Electric Bicycle Parts | Izip Bicycle Battery | Izip Bicycle Charger | IZIPĢ4V Electric Bicycle Battery - 24 Volt RMB Rack Mount Battery Pack with BUTTON Terminal for Currie Electric Bike, eZip Trailz, iZip Electric Bicycles We have 5v at blue on the controller connector.(Ongoing lead to motor disconnected) A break in the blue sensor lead motor side of connector block would still leave us with 5v at the connector? What effect a short in the blue sensor lead or a failure of the Hall sensor itself would have I don't know. So fwiw it seems to me in my ignorance that there is a fault on the blue hall sensor wire or the sensor itself. Measure voltage out from controller at 5 pin block with ongoing lead to motor disconnected ie (disconnect 5 thin sensor wires to motor )from controller. Setup as above but disconnect 5 pin block connector. Same results so no problem in connector block? ZERO voltage constant.Ĭheck as above but on controller side of connector block. Voltage cycles 0v-5vīlue to Black and turn back wheel slowly backwards. Green to Black and turn back wheel slowly backwards. Yellow to Black and turn back wheel slowly backwards. Measure voltage on motor side of 5 pin connector block. Blue to Blue.Yellow to Yellow.and 5 thin sensor wires via connector block. All show infinite resistance.Ĭonnect motor to controller. Measure resistance between each fat phase wire in turn and motor case. Quote amberwolf "Those should all show shorted together. All 3 tests show no measurable resistance. (3 bullet connectors and 5 pin conector block all seperated) Measure resistance between 3 fat phase wires. When I referred to sensor wires, I was referring to the 5 'thin ' wires running via a 5 pin connector block from the controller to the hub motor. When I referred to the 'supply' wires in my last post ,I was referring to the 3 'fat ' wires running via 3 bullet connectors from the controller to the hub motor.Should have called them phase wires. Many thanks for your quick and comprehensive reply. But if you had a problem with the phases on the controller, the motor wouldn't run at all, and would be hard to turn by hand if the FEts were shorted. If you mean the motor phase wires, then they should show at least very high resistance between each other. If you are testing between signal wires, then they should show 10k-20kohm resistance becuase your'e measuring between two of the pullups, basically. If power is still present on the controller, there's no valid reading because there is a voltage present and resistance can't be measured accurately. If you don't get that on any of them, something is wrong with all of them, or with how the measurement is being made. Thanks!Ĭlick to expand.Assuming you mean the hall sensor signal wires, then if that is with power and motor disconnected from controller, and measuring from 5v to each signal on the controller side of the wires, then you should get something like 5kohm to 10kohm, from the internal controller pullups (resistors on each signal wire to 5v). Some of the colour coding in the 'electrics box ' seems a bit off but can'tĪny help, comments, ideas gratefully accepted. I can't start the motor by pedalling the machine with the battery connected whatever I do with the throttle.ĭon't know how old it is but controller (Ananda) is dated 2006. Once running, turning the pedals slowly and wheel speed increases as I understand it should? sometimes nothing ,but turning the wheel backwards a bit and reconnecting power, and it may run. Sometimes the wheel turns, other times there is a whirring from the motor but wheel doesn,t turn. The only way I can get any action is as follows.Ģ.Connect battery. Trying to get it going!Ĭame without batteries or box so I am using 2X 12v car batteries in series to test it mounted on rear carrier. New to e.bikes, bought this Izip Ezgo some time ago.
