12 FET controller board not working after installing FETs

[kZs0lt]

2.5 amp no load current with BMC MK1 motor @~43v, aprox. 330rot/min. It does seem a bit high, but acceptable?

ok, i thought you meant idle current.

Yuppi, I finally succeeded to program the board.

I wasn't talking to the programmer, that was my problem. As I have told, I installed a ("Prolific") USB to serial port converter driver, but didn't realized that it mapped to com7. I tried all four com ports in the program, and except com3, all other ports yielded "This comm is no use, please try other one!", so I thought the USB converter was using that 3rd one, because my laptop has no serial or parallel port. After checking in control panel hardware/device manager, I found that the driver attaches to com5, com6 ... com8 depending on which USB I connect to (having 4 USB connections). But the software can communicate only with com1-com4.
I eventually succeeded to map the converter to com1 from the driver settings, and now works wonderful, it reprograms in 1-2s. I have no idea what is com3 used for.
Many thanks to you guys, especially Methods, who was helping a lot by PM.
I will try to hook up the motor to controller tomorrow, and come back to report whether is going with the reprogrammed controller or not.
I am hoping I will get this working, if the controller can be programmed, it couldn't have serious damage. It might work out to be some silly mistake.

Cheers, Zsolt

This seems to be the same problem that I am having. Exactly what did you do to map the converter to com1? I tried mapping it to com 1-7 and the driver will not start. It always gives me the "This device can not start. (Code 10).

You have the wrong driver installed. It doesnt like vista either. I can send you the one i used to program my controller. Just pm me.

I used the posted driver for the early version software on Vista and it works fine for both my new and old controllers (V1 and V2 software).
I think it is a case by case deal.
