The throttle sticks. Not electronically, it sticks mechanically. It's a thumb throttle and it doesn't return unless I pull it back by hooking my thumb under it. Any suggestions? Can I lube it or will that but the electronics? Will my Smart Pie throttle fit?
I realise your particular problem was not due to internal friction, but if it was, it should be OK to apply some non-electrically conductive lubricant to the moving parts to reduce any unwanted internal friction.
I suspect that your Smart Pie throttle will have the same connector as the Edge, but it does not necessarily follow that they will be wired the same internally just because they use the same connectors.
I know there have been slight differences in the throttle wiring on some earlier versions of the Magic Pie, therefore I am unable to say that the later MPIII, MP4, MP5 MP Edge and Smart Pie throttles are safe to interchange.
If they both have the same later harness connector shown above, then they may well use the same throttles, but
if the throttles were wired differently, this could result in damage to the control harness, the controller, or possibly both.
I would check the internal throttle connections in relation to the individual pins by carrying out a continuity test with an Ohmmeter, in order to confirm that both throttles were actually wired the same.
