Okay, i've been told the B coil is the vertical one but have questions about testing the coil.
I've just run a multimeter across the wires after disconnecting the coil. There are three wires, red, yellow and black. Using the '200' setting on ohms on the MM i get nothing showing when connecting the black to either other wire and i get the reading 1.1 when connecting the red and yellow wires.
I thought i had read another post with the correct readings i should be getting but having re-read it I am not sure if they are right or not. Do you know what the correct readings should be?
