yes it will blink on the negative side which indicates the hall effect sensor is sending a pulse signal to the coil when cylinder is at top dead center also older systems with points will do the same. sometime the positive will blink also because the starter draws over 100 amps and voltage drops at coil

What would make a 1995 Dodge Intrepid stall when you are driving and hit the brake to slow down?
the camshaft sensor may be bad. It is connected to the driver side of the engine block, and you can check to see if that is the problem by turning the ignition on/off three times. On the third time, leave it in the on position, and the "service engine" light will begin to blink. It will blink twice, pause, then blink three times to indicate a "23", which is a code that can be called in to the dealer, or easily accessible in a Haynes automobile book.
How do i find out what the check engine light is on for on a BMW?
first you nee to check and see if your car is referred to as OBDI or OBDII if its ODBI then you start with the car off.. turn the key to run but do not start the engine.. at this point you have less that 5 seconds to push the gas pedall all the way to the floor and press the overdrive button five times... then the check engine light will stay on.. and then blink... next its going to blink out the code for you for ex. blink-pause-blink blink-pause blink blink blink-pause blink n that would mean the problem code is 1231 just Google BMW problem codes and use that dcode to find out what the issue is..
Why do Toyota Cressida dash lights stay on after engine starts?
Are you talking about the lights that are under the gauges, that read "check engine", battery, oil press, etc.? If so, your ecu is not getting a STA signal, or start signal. You need to test for ecu trouble codes. To do this... go under the bonnet and find the DIAGNOSIS box. Jumper terminals TE1 and E1. Start the engine. Watch the Check engine light blink. It works kind of like Morse code. For instance... BLINK BLINK ... pause ... BLINK BLINK BLINK would be a code 23. This site can help you determine the meaning of the code. Good luck. http://docs.azsupracentral.com/Engine%20Error%20Codes.pdf
