Probes touching…

So the 1 reading was just the meter with both probes in but not touching, attached is with probes attached

Well it was .91 on all three on the black probe and the red probe it started at 13.6/15.1/21.2 and consistently started to rise Dan

no problem. I went and put red probe in black and black probe in coloured wires and then did exactly the same with black probe in red. Same as before except now 0.91. This definitely isn’t my area of expertise!!

Thanks! I tested this way and thought I’d check if I’m doing it correctly? When I tested by touching the male blue, green or yellow I got nothing so assuming that was wrong. Red probe in red battery, numbers kept going up for each wire. Red probe in black battery, all readings 0.93 Cheers Dan

Some more images if I can upload. @D8veh i can’t get that sensor to move. Disconnected the throttle cable as a possible source of the problem but there is no power to the pedals and after a minute the power on the controller went from 5 to zero and blinking. Is the unit basically dead and I need to replace the bms and controller etc?

36v

Thanks for the advice on that, will give it a go asap. Wiring all looks normal to me.

Happy to do that, is there a website I can see a plan of connecting so I can check against what’s there and what should be? Bike was purchased as a complete build so I don’t have schematics for the installation

So I should get into p15 and up the cutoff to 32? Still , I don’t understand why the controller is showing random sub 28v values when it’s definitely not

Just to follow up on this one have tested the 36v battery with a multimeter and it’s showing 40.9 - is that correct or is it in fact a 42v battery? I cannot see from the battery. I have put the controller into p3 and it’s at 36v and p15 is set at 29v as the minimum. When I see the voltage on the display it’s bouncing around between 24 and 27 but under 29 hence not working. I can’t figure out how to post the video on my phone here but what does this tell anyone? Controller broken? Thanks Dan

Appreciate the time, can't currently check as wife is using bike (as a bike!) for work so will be Sunday basically but thanks re first tip, I will certainly check that. Info: Cannondale Adventure 1 bike, with Hailong 36v battery, 250w motor, controller as you know. LBS had the bike as wife came off so decided best to get it serviced - there was an issue with one of the cranks (thread) but it appears in investigating the worker has done something that stops the pedal assist - damn bike weighs a ton so hard to see under! Will also look and post a picture. So it seems as if my wife has been using it as a throttle assist method bike, so pedal as normal, give a boost especially when going up hill or into the seemingly neverending wind, and then back to no throttle assist when down hill or wind.

Pedal Assist is non functional now after a lbs attempted some repairs but the crank was not reconnected so currently just the throttle

Thanks for the reply Self learning wires - I wouldn't know - there are a couple that are disconnected such as the green one but that didn't seem to go well. Is there a simple way to identify if I have those and if so what advantages are there? I will research anyway. Agree re history - all was fine until about 3 weeks ago when the same thing happened - the first since purchase. Possible condesation issue with the display as wife had covered the screen in clingfilm to act as a water cover. After the intial reset the battery display seemed fine but as soon as I turned the throttle, the issue happened immediately, so I traced the cable and unplugged it but then I couldn't seem to get the controller to connect again.

Afternoon I have a 36v battery and the above-mentioned controller is set to the correct voltage in P3 but I am quite often switching the controller on and getting the flashing empty battery signal despite the battery being fully charged. Checked connections and one green wire was disconnected but when connected that seemed to cause the motor to hum so disconnected,,,checked the rest and seems all fine. Switched back on and the battery is now showing as full but use of the throttle immediately replicated the issue. Double clicked the centre button and shows the voltage flicking around 25.5-27.6 and I believe it needs to be above 29 to function? Reset again and instructed wife to not use throttle but it didn't like being unplugged. Should I invest in a new controller setup? Thanks for taking the time to ready Dan

sold already!!

Just to update on this, drove to east London on Monday morning and picked the bike up after a few test rides. Hefty bike but in a good, solid and well built way. Conversion all looks good, connector to hub is facing down which I believe is the right way (to stop water ingress?) and all is good. Wife very happy. Thanks for all the feedback and so forth. Dan

Thanks. Then I'm thinking of this https://www.ebay.co.uk/itm/405503653660?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=bA_3Kl5KTuu&sssrc=4429486&ssuid=uAELTJt4Rde&var=&widget_ver=artemis&media=COPY By the time I buy the bike and a kit I'm about £700 in?

Hi Having read through a number of posts, the repeated comment was to answer the following questions and provide an image of the 'donor' bike so here goes: This is for my wife to help with commuting for perhaps 10 miles in total and maybe joinging me for rides of say 20 miles; The best way to start is for you to write down all what you have and what you want to achieve. How heavy are you? Lets say 9st What type of rides? Mostly commuting for 10 miles round trip, occasional day out with me so 20-25 miles How steep are the hills? Cambridge area so basically flat as you can How fast do you want to go? legal limit is fine Any other desirable characteristics? Not really. Image below is the basic design of her bike as in step-through, rack etc so I imagine the battery will be on the rack or under the seat? Show a picture of your donor bike.

Thanks for confirming my doubts!

For sure that's fair enough - as you say no guarantee either way. On a separate note, anyone got any thoughts on this: https://www.punkride.com/products/hidoes-bn1-electric-bike?variant=45623770513557&currency=GBP&country=GB&gad_source=1&gclid=Cj0KCQjwqcO_BhDaARIsACz62vMAxrLV0Tx4KHjzhuEyoHmW1gpHDztkvjKDrj1tX5JDy4JAhiEpmYsaAuLeEALw_wcB I have some reservations but thought I would ask some experts!

what do you think about it for a lady of about 5ft 6"?

extraordinarily kind of you to do that for me!
