With your sister's Stoweway, in those cases do the battery level lights not come on when the battery button is pushed? And is it immediately fixed by plugging in the charger? I've had that miles from home and assumed it was a protection device (cut-out) inside the battery (no matter how careful I was to turn the battery completely off before sliding it in and out of the bike etc.)

Yes, an update. I emailed Raleigh support, who said: I have provided the part codes for the parts below. We do not have any stock, (currently showing as Mar 2022) so would need to be ordered through a bike shop. Find UK Raleigh Bike & Electric Bike Dealers | Raleigh UK Part code for controller - ABN410C001618 Part code for display - AA504011760 The dealers I spoke to (including Halfords) came up with the same date. Cost of the controller part was given as £118.80 (plus fitting) Then, at the weekend, I bought a second hand Stoweway and solved my problem. But, now having a duplicate set of parts, I could try a few things and it seems the fault was with the DP15 display. (i.e. new display lit up when connected to old controller, although I didn't go as far as activating the motor). At least the DP15 has a possible alternative source (and is much easier to fit): https://hollandbikeshop.com/en-gb/bicycle-parts-electric-bicycle/tranzx-e-bike-parts/tranzx-displays-parts/tranzx-display/tranzx-dp15-e-bike-display-for-f15i-black-684974/ I can't guarantee any of the above - you really need spare parts to diagnose the problem but I couldn't find a raleigh dealer that had any Hope that helps Ps. the link above states a 30-day cooling off period

It is a BL21. It has 4 pins and the outer two are 40-41V (unloaded) There are two inner pins that don't show any voltage Are they supposed to be 5v? That would explain a lot. I can't find any documentation to say that what the pins are for

yes I am getting 40V to the board (across the two blobs of solder to the right of the capacitor) even so, no sign of life from either the display or bike lights It's only my hunch the fault is somewhere on the controller though

Cyclebuddy, you are amazing! I will ask at Halfords next opportunity. Giving up hope, I decided I couldn't make it worse by opening up the controller and taking a look. Everything seems OK on both sides of the PCB and the power connection to the board says 40V. (There is white sludge underneath the capacitor but I am guessing the capacitor is folded down to fit inside the box and the white material is to stop it bumping into any contacts on the board - there are no signs of leakage) I will see if I can measure any voltage going into the DP15 display but it is difficult to diagnose further without a spare of everything

Thanks Cyclebuddy. It was actually Evans I bought the bike from originally. When I asked why they used to have the diagnostic tool and not now, they said their computers had had a "refresh" (since they were taken over?) and no longer feature the software - not that it would work on my bike anyway now the display is dead. I was wrong earlier- Evans no longer sell the Stoweway (the other shop does but it is out of stock) Thanks for the J D Components insight. I still cannot bring up anything on the web for that model of controller so it seems you have to be in the know. Hoping somebody here can help

The electrics in my 3 year old Stoweway have decided to pack up and nothing comes up on the handlebar display when the battery is inserted. Although now beyond the 2 year electrical warranty, I took it back to the shop I bought it from whereupon it started working again as I tried to demonstrate. They said they would take a look - which I imagined involved plugging in diagnostic equipment into the USB port - but when I picked it up it was completely dead and they said there was nothing they could do. They cannot get parts and don't have the tester anymore. I tried another Raleigh dealer and it was the same story. However, both of these stores will sell me a new Stoweway, so there must be spare parts somewhere?! I have tried locating a replacement for the controller myself - TranzX CN41 controller - but I have found NOTHING! The battery is healthy so it seems a shame I cannot extend the life of this e-bike - any thoughts appreciated, thank you
