All the components have turned up to make the EGR cheat, ordered some prototype board and miniature relay. Bugger pins not on same spacing as holes in board, never mind I can feel some bending happening! Just hope the resistors are correct rating cos its said as example 4K7 and it took that as meaning 47K (not that it looks like you can get one marked up as 4K7).
Not the first cheat circuit I have made, did one for my lads R1 to bypass the exhaust flap.
No, 47K is not 4K7. 4K7 is 4.7K.
Basically the letters R, K and M are used in place of the decimal point. R indicates ohms, K thousand ohms, and M million (meg) ohms, all followed by a decimal point. So..
4R7 = 4.7 ohms.
47R = 47.0 ohms
470R = 470.0 ohms
4K7 = 4.7 thousand ohms = 4.7K
47K = 47.0 thousand ohms = 47.0K
470K = 470.0 thousand ohms = 470.0 K
4M7 = 4.7 million ohms = 4.7M
Just be thankful you're not dealing with capacitors. 4700pF = 4.7nF = 0.0047uF.
