Suzhou kunteng. I wonder how we do change hall angle and is it 120 or could it have been changed

Default parameter is 120°. I've also asked about c2.

I'll try again tonight. Just had a response from China. Phase selection is not automatic. I've asked how to change. I see that you can add an extra shunt and that there are places on the board that seem to be were you can add jumpers. So we'll wait and see.

Hi d8veh, thanks for your help tonight. I found this regarding P5 is power monitoring mode, when P5 setting is 0, the power monitoring is the "real-time voltage" mode. Namely, it is the method to determine the battery capacity based on real-time battery voltage. When P5 equals to a...

I have had a look on ES, but don't seem to have found any with the same problem. I still get only 3 good combinations of phase and hall, but they all seem rough and power cuts out after a few seconds. Does the slcd3 and s12s work with both 60 and 120 degree halls? The tester indicates that the...

Hi d8veh, I bought another controller from BMS. Seems to be a better build quality to the first one. However I don't seem to have any success here either. Using a tester, I have checked motor, controller and throttle, all seem fine. When I check the phases I have rotating lights which are...

I have just ordered one. BMS still working on their customer service, no reply to my emails:)

I replaced the 4 FETs and LCD was then lit and motor jerked. But no self learning and started to do phase wire and then hall combo. After about 20 minutes 5A fuse blew and now ground and live are shorted again.

I replaced the four FETs and had power to the lcd and motor turned/juddered. But no proper movement, so changed phase writes and then started to change hall combinations and phase. 5A fuse blew after half an hour and now I have a short again between ground and live. I think FETs have blown on...

Well I tried that but it wasnt happy and now it has a short circuit again with one of the phases dead again. How should a self learning system be set up to learn?

Hi d8veh, I have power. What connections (phase and hall) did you use for your s12s to gng motor, i.e. which colour to which colour? Thanks

Th red wire has a single melt mark on it about 2 cm from where it joins the board. I can only assume it was touching something else. Two likely suspects are the small cap (furthest from your arrow) or the brown two legged object. I have emailed BMS, just wait and see wait for their response...

I took the heat sink off, so I could look at the legs better, but also found that two of the fets (on the green phase) had a crazed look to their backs. http://s100.photobucket.com/user/charleshartshorneying_chase/media/IMG_20140603_222622_zps6e88d219.jpg.html

Finally, found some damage. Red wire for speed sensor slightly melted and one end of grey cable (ABS) not attached. Though this last could be after the fact.

Yes. LCD is disconnected. Regulator looks OK. What does the back of your board look like? How good is bmsbattery customer service?

Hi d8veh, there don't seem to be any bridges. However the section closest to the extra wire seems very close to the black and the same on the other side closes to the FETs. But the gap if there is very hard to see.

Battery leads polarity is correct and correct when connected up to each other. The middle set of four fets are for the green phase wire. I have just measured again and I do get 00.4 measuring from middle leg to right leg. Measuring from middle to left leg I get 92.9(closest to the two caps)...

Probes in positive and negative give me 00.4 at 200 ohm (0.00 at 20k ohm). I'll go and check the battery polarity now. How can you tell which are the high sided fets? green phase wire to right leg all fets measured 00.4 (at 200 ohm scale) green phase wire to left leg fets measured 90.2...

Hi d8veh, measured using the resistance scale, meter set to 20k ohm. ground to yellow 9.95 ground to blue 10.00 ground to green 0.00 positive to yellow 9.95 positive to blue 10.00 positive to green 0.00 Then for clarity tip of red probe connected to tip of black probe 0.00 at 20k ohm and 00.4...
