Ah yes I know it. Its got a little motor and circuitry in there hasn't it? I opened it up out of curiosity the other day. How would I tell if its working properly? QUOTE]
well first you could go for a drive and sit in 3rd gear then put you foot down. when you reach 3k to 4k revs you should feel a surge of power.
Or take the cover off and you see the motor keep that pushed down with a screw driver and rev the car hard, if it spins it works.
