and what does a code 355 mean??

Thanks James

I think you got a code 3, and the 55 means end of codes.

whats a code 3??

does anyone know what a code 3 is? if not does anyone know where i can find out on the net??

I guess there is no code three. Read that and try your method again, see if you get a different reading. Best of luck.

Hey thanks guys but i desided to get rid of my headache so thanks anyways and now i have a new problem.

i tryed it again and all i get is it blinks three times then pauses then blinks five times then pause then blinks five more times then quites blinking.

strange, never heard of a code three either, 55 is end of code, 1-2 is bad battery connection, check your ground.
