Re: Checking for faulty sensors
you need a scope.
A magnetic senser (2 wire will give fluctuations on a digital meter) but it is better to see a wave form.
It will rise above the 0 volt line as a pos voltage then fall below 0 as a neg voltage.
You would expect about a 2v + and a 2v -
If your digital meter has a bar graph set it to mV and watch the bar graph not the voltage reading as it gives you a better idea.
It will rise and fall as you crank.
If it has 3 wires it is a hall effect ,it will be a square wave ,on off and if it has a 5v supply you would expect 4.7 to 5v.
It will have a 5v supply and a ground ,the gound is senser ground not chassis ground.
you will need a scope for this one ,a meter will read it but will usually give an average so you may only see 2.5v ish constant,scope is better.
If you say its to hard you have
