I would just like to say thanks to all who offered their advice. My bike is back up and running and I have happily commuted to work and back with no problems. I have learnt a lot in only a few days. Many thanks again.

No it is not the brake. disconnected the brake cable so no contact with rims. Def. coming from hub motor

I just made a new shunt out of longer and slightly thinner wire and I have got slightly different readings between the 3 good combinations now. Readings were between 0.72 and 0.80mv for one combo and the other 2 were flicking up and down from 0.75 to 0.90. I have gone with lowest option. Thank...

Great news! Made the shunt connected up my multimeter and got some readings. 3 were initially much higher (5.0+ mv) then setttled down. These were the false positives that you mentioned I think The other 3 readings were all very similar. Full throttle initially and all went up to 1.8mv...

By the way, it was mentioned somewhere that there will be 3 out of 36 possible combinations that will result in forward movement. I have 6 working combinations all spinning forwards. Other combinations span forward too but made interesting noises. 6 were all ok but some made the wheel spin much...

Thank you. I will make the shunt tomorrow and let you know how I get on.

Ok great. I have a newish bosch iron that does not work so will use 100mm from one of the wires from the lead (would that be 2.5mm?) or I have an old extension lead cable. Don't really want to have to go out and buy a big reel of 2.5mm twin and earth. I will use the croc leads to connect to the...

brilliant. last 2 questions (I hope) 1. Where is best place to get the 14g wire and 2. What wire do i need for leads to probes? Can I use croc clip test leads and just cut crocs off one end and solder to ends of 14g. I can then clip crocs onto probes?

Ok, I am learning slowly. Thank you so much for your help and patience. Does this diagram look right?

Can I leave the + wire connected as normal and just use 100mm 14g wire with 2 spade connectors at each end to connect into my - wire, and solder in two smaller wires to the spade connectors to connect the probes to? I don't understand why I need the red thick wire too.

I don't know where the 3 smaller wires are going and how this shunt would connect into the black -ive wire.

To be honest I don't know how to make the shunt! I have looked at you picture of yours (on the paper plate) and don't understand what the wires are for. I can see 3 small ones and 2 larger ones (black and red). I am really clueless. Sorry

Just bought one of these as I thought I could just connect it and it would measure current!! I really dont know what I am doing do I :( http://www.amazon.co.uk/gp/product/B000JQ4O2U/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

Apologies, I am still finding my way around how to use this site and I think I have started a conversation as well as replying here. I have tried to have a look at your instructions about how to measure the current and although I feel that I am quite a practical person, I am unsure how to...

Thank you for the information but I am really new to electrics. I have already bought a multimeter and was hoping I would be able to connect the prongs to some of the wires and get a reading. I'll have a good read of your information again later when i have more time.
