Hi AlanGlad to see your topic is still alive crystal john, (but not of course that you are experiencing problems)...
Your old controller looks very similar to mine on the Probike and only 8 wires to/from the rear hub motor and is also 24v, and I have finally decided to follow vfr400 and Nealh's advice and purchase the PSpower controller , LCD3 display ect. but perhaps a bit late to order now as Chinese New Year looms in about three weeks, and anything ordered now MAY be lost in the ether...
is the image in your post a copy of the instructions that came with the new controller, thanks for uploading that as very useful.
I hope that you don't mind me hanging onto your coat tails on this topic, but hopefully it will save me pestering vfr400 and Nealh when I do this work on mine...
Good Luck again John... and thanks to vfr400 and Nealh for their continuing expertise.
Yes the image I posted is a copy of the instructions that came with the new controller. It is one of 2 pages, clearly identifying the connections, which was very useful to me as I am completely new to this.
Here is the other page:http://www.pswpower.com/ven.php?cargo.2016-3f-3f7c
This new controller looks to be very high quality, all the external wiring connections seem to made of good quality materials, and the L.C.D display and control switches are excellent. I'm looking forward to getting my problem resolved with the assistance of the knowledgeable people on this site eventually.
I have now checked continuity of the hall sensor/motor wiring plug from female to male and that is Ok. I removed the rear wheel and removed the motor cover plate to see if I could access the connections inside to enable me to test the continuity of the vulnerable wires which pass through through the axle, but was thwarted by no accessible connections as everything is secured by a web of fine nylon threads.
Next I intend to check the individual hall sensors ( kindly advised how to do by vfr400)
just seen danielrlee's advice ,and as I am using a stand alone speed sensor, I will set the parameters P2 to 1 so will attempt that soon.
