Hi,

Just a bit of help fault finding a non functionate Stepper. The item below (apologies for crap picture, only mobile handy at the time) came off a Rover V8, not sure of make but has following markings:

704409
B1884

Basically it seems to be always fully retracted i.e it lets air into the manifold constantly.

I've fiddled with the start position is MS to no avail, coil A and coil B both measure 58 Ohms which would seem to be correct, connected to 25, 27 29, 31.

Have I missed something on building the MS board

Using MS II V3 Board with MT 2.25 code 2.36

Any help appreciated.
Thanks

Darren

checked all above so can only assume the stepper is at fault.

Thanks
