ps, i blew my led`s cos i got my anode and cathode mixed up!! is this correct; annode the positive and cathode the negative....come on you buddin electronics wizzards, come back to me with this one so i dont blow any more !!lol
ps
thanks people who helped me out on this one. im now back to working on the hesitation/holding back on quarter throttle. lol

well i suppose a well done is in order les, at least you got rid of the warning lights....
using a mutli meter is tricky, you can get readings from 8v to 11.5 v, very quickly so a bulb is better..i would expect a 12v bulb to give some reaction with 8v thru them tho.....you dont have to go for anything fancy ..less that a quid from maplins, just make sure it is 12v and you will not need resistors
The anode of a device is the terminal where current flows in. The cathode of a device is the terminal where current flows out.
cheers
