Last night The Eagle was being naughty. Power started up fine for a few minutes riding, then coasted down a hill. At the bottom, when I started pedalling again, no power! Stopped, switched off the power at the key and turned it back on. Nothing, not a sausage. Tried again a minute later and all was fine again for 2 or 3 miles, then power dropped to level one or less and would not provide full power. I switched to throttle and full power was restored. Closed the throttle, and on twisting the throttle back again only very low power available.
Stopped again, switched everything off and back on, all was fine. I pedalled another mile or so under full power, stopped at a junction, then no power at all on throttle or pedelec function when I went to move off again. This morning I have disconnected the throttle and both brake switches, and just turning the pedals the problem persists. Mostly it will start on full power just fine, but if I stop pedalling and restart again, only very low power is available or sometimes none at all.
If I switch off and on again, it usually cures the problem until I stop and restart, it would seem there is a problem with the start up circuitry in the controller. When it doesn't want to go at all, there is an audible click but no power. Its as though just as the power is starting it gets switched off or reduced to very low power only.
The effects seem about the same whether I use throttle or pedelec function, a random chance of starting up or not!! When it runs properly, there is full power available and the bike rides normally, the problem starts when I stop applying power and then set off again. I have checked inside the controller compartment (in a box underneath the rear of seat battery) and it was pretty dry in there and all connections appear sound.
The battery is showing four lights and seems fine and provides full power without problems. The motor seems normal when its running. Seeing as the intermittent problem occurs without throttle or brake switches connected, my meagre analysis suggests some component in the controller is breaking down!
The bike has been out in some heavy rain lately but I cant find any water anywhere. The bike was fine 4 days ago?
Are there any further tests I can do to further isolate the fault? Is my controller toast?
Its a Freego Eagle with 250 watt Bafang.
