Hello out there, I’m more or less new to all this and am looking for a kit to convert my bike to electric assistance. I’m currently only interested in pedal assistance but will perhaps occasionally want the bike to self propel without any pedalling. Also I think with a minimum of 3 levels of...

Ah well, the original resistor wasnt positioned as I have positioned the new one. It was set at about 45 degrees sloping up from the PCB. The end of the original resistor was almost if not touching the PCB where the crater/burned area is. I've added another picture. Many thanks bobd

Ah, I can see the reason for your comments. The 3 spiders legs are actually very fine scratches in the surface of the PC. And what might look like a solder blob is actually more like a shallow crater burned into the surface of the PCB. I'll take some more photos tomorrow and forward them on...

Hello again, and I'm back with the latest saga of the poorly EZEE. So, the 5 volt regulators turned up this morning and I've spent a few hours in the workshop practicing my soldering skills and soldering a regulator back into its position on the PCB. That's where the first bit of iffy news...

Hopefully all will go to plan and then the leftover resistors and regulators will be sent to gather dust in a far flung corner of a cupboard never to be seen again, and so I'll be quite happy to donate them to wherever free of charge. Many Thanks bobd'

AaaHaa. The new resistors turned up today and so I've fitted one. Still no 5V regulator fitted though but suddenly there are some readings as follows. The resistor readings are 37V at one end and 31V at the other and its resistance is 197 Ohm. The reading from the vacant holes for the 5V...

Hi again and thanks for the encouraging reply. I've been having a ponder over what comes next with this little conundrum and guess its just a matter of waiting until the parts arrive and then installing the new regulator and resistor and working back through the previous notes and going through...

Right, here we go with my findings. THE REGULATORS As you said regarding price it seems that from ebay + the P&P which is about as much as the components the price gets bumped up. On amazon (with prime) they are double the price to those on ebay, but there is no postage, plus I can easily send...

Ah, right, yes, in other words I aren't exactly full of confidence with the old multimeter, but after a chat with a mate who is I've done the recommended stuff and checked the resistor (the one next to the 12V rgulator) and the reading just stays at 0.0. I've had the multimeter dial set at its...

Well I'm back and no burnt fingers etc and the little black 3 legged thingy is out. The holes are clear and any solder splatter which got on the PCB has been delicately removed. Unfortunately the readings are still the same. I get 37V at one end of the resistor and at the other end 0.3V and one...

Arghhhh, remove that little 3 legged black thing indeed. Well that certainly will test me, but best foot forward etc etc. That'll be a job for tomorrow, and a steady hand and perhaps a third hand form a friend. Oh yes I forgot to mention, the outer painted type of layer on the resistor has all...

Hi again and the readings from the resistor are 37V at one end and 0.3 at the other end. I've taken this measurement between the main black wire going into the PCB (which I believe is called ground) and each end of the resistor. However I don't know what the readings should be. Thanks Again bobd

Oh yes, I forgot to mention that I don't recollect trying to get any readings between the white and black wires.

Hi again. Just back from another session with the mustimeter and there is definitely 36v at the red wire at KSI. For the next checks I have assumed that I'm going between a black wire and the legs on the regulators to establish some readings. So the readings from the large regulator read 0.6V on...

Ah, I seem to have a new version of your last message. I'll go and investigate a bit more. Thanks Again bobd

Mmmm, I'm back again and a bit confused as your last message seemed to change. Not sure now whether or not I should continue and bridge the blue and red wires as first seem to be indicated. I've been back and had another look and and the blue wire definitely goes to IN and have taken some photos...

Thanks and back to the workshop. bobd

Much to my surprise I think I might be following this and can report back that the cable from the control box to the display unit has 6 wires. Yellow, red, black, blue, green and white, and if I take a reading between the red and any black wire I get 37v. Also I've already got the control box...

Thanks again everyone and I have now re borrowed the 3 car batteries. They aren't new but each one will individually illuminate a 21W bulb and the the total accumulated voltage is 37 volts. So, the first thing to report is regarding the 2 frayed wires which are 2 of the 6 that go from the...

Hi again and thanks for the help so far. I'll need to get hold of 3 car batteries again by the sounds of things and that will take a few days and so I wont be around until I get that sorted. Another problem I'm having is with the site site and am struggling finding my way back to my thread. Any...
