    Hi guys,

    ok i fgot all the parts in, put her togther last night and did the motor test, all motors test out fine except number 4, it tries to start spinning but only gets half a turn and stops and then try again and stops, just like an intermitent go-stop-go-stop-stop but it only goes half a turn or maybe 3/4. i tested the bl controller, from + to all the mosfest and they all read 8.something and start slowly climbing maybe 0.1 (meter set to 200k) every 3 seconds, then did the ame test but with the - and same result. checked the PD board for shorts and everything is fine.

    any ideas?

    Thanks, Jean. For others who read this I suspect that Jean found that one of the solder joints on the BL-Ctrl MOSFET transistors is bad.
    Is that correct, Jean?

    ANdy.
