Crank sensor check

[HOTSIX]

Guys whats the easiest way to tell if your crank sensor is toast other than look see....?
Voltmeter probed to the wires ? What voltage to look for ?

If you've got spark and fuel the cam and crank sensors are ok. The cam sensor could be off but it has to be working to get fuel.

if you get a signal at the injectors then its ok
test i told you about last night..

probe the "B" wire (center wire on the plug connector) with the positive wire of a voltmeter, and ground the negative voltmeter wire.

Take 2 readings (Ignition on):

one with the sensor facing a vane on the trigger wheel,
one with the sensor facing "air"

I'm not sure which will be which, but ONE test should show from 9-11 volts, the other test should show about 1/2 volt.

If you get no voltage variation, the sensor may be bad.

If you get no voltage, your not getting power to the sensor.
