Powabyke mk1 classic

[n.r.evans]

HELLO
I own a powabyke mk1 classic which has given good service until last week when it got knocked over now when I turn the ignition key the motor runs at constant full speed, has anyone else experienced this problem any help greatly appreciated

its probably either the throttle shorting eg. broken wire or the controller . try disconnecting the throttle first.

hi
Thanks for the response I have removed the throttle plug/wires from the printed circuit board

Hi ,Thanks for the response I have romoved the throttle plug/wires from printed circuit board and its still the same Iam begining to think the cicuit board may be damaged

I have same problem with my Mk1. If I find a solution I will post it here, would you mind doing the same?

Cheers,

The MOSFET on these controllers can fail short circuit and cause the motor to run full power. Assuming there's no wiring problems it would be the first thing I'd check.

Thanks for the reply but what is the MOSFET and how can I check this out

cheers

Thanks for the reply but what is the MOSFET and how can I check this out

It's a fancy transistor which (normally) controls the power to the motor. On the two controller boards I have in front of me it's marked "Q3" and is the rightmost device screwed to the heatsink.

As for testing it, that might not be straightforward without desoldering it but Google "testing mosfet" and see what you think.

Hi I think you have a brushed motor easy to tell if you have only 2 wires to the motor

Not 3 heavy leads and 5 thin wires

Thanks for the reply but I dont have the equipment or the electrical nouse to check this component,I am aware that buying a new printed cicuit board may not be the cheapest option but it should solve the problem as the mosfet is on this circuit board

cheers

Hi
thanks for the reply have checked out the controller on e/bay its not the same as the one on my Powabyke
