Didn't you get the stim board ?

It uses a 9v battery to power the main unit and has adjustable resisitors for all your sensors.

Liam, any good 12V source is fine mate, just make sure you connect to the correct pins.

Checking for comms is defo the no1 priority, you need it to setup the TPS limits before any 1st start attempt.

you loaded the software and file up ok dude ?

what about a HDD supply on your PC ? they are 12v

[liam012]

you reckon that'd be safe - definately the easiest option open to me at present -
just hook up one to the yellow 12v feed and one to the black earth?

Im not sure on the current draw, mibby stick a blade fuse inbetween.

i have powered neons and all sorts from HDD supply.

From my play today with my MS don't bother to try and run it from a PP3 9V battery, i had a brand new 9v battery, it lasted all of about 2 minutes...

So you wouldn't recommend an old car battery when up flashing maps!
