... http://carsntoys.net How to test an inhibitor switch or neutral safety switch. ... This was performed on a 1997 Nissan Maxima...... I have a 2000 Nesson altumia I can't get it to start up it turns over but no start what's up with it.
Normally, only automatic transmission cars are equipped with a neutral safety switch. There is a switch on the clutch pedal up under the dash that will not allow the starter to engage unless the clutch is depressed.
Make sure that the car is in park (or neutral on manual transmitions) with the emergency brake on. Use a temporary starter switch that you can buy at an auto parts store. Connect one end to the small post on the starter. Connect the other to the battery + (positive) terminal. Tap the starter switch and see if the engine will turn over. If the starter does not turn over it's the starter. If it does turn over, connect a test light to the small starter terminal wire and ground the other end to the chassis or - (negative) terminal on the battery. Turn the ignition switch to the start position and see if the light turns on. (you will have to hold the clutch pedal down on a manual transmition car) On a car with an automatic transmition, If the light does not turn on you have narrowed it down to the saftey switch on the gear selector or the ignition switch. On a manual transmition car you have narrowed it down to the saftey switch on the clutch pedal or the ignition switch. Both of the saftey switches can be jumped (temporarily for diagnostics) with a small piece of wire (stripped back about 1/2 inch on both ends) inserted into the terminal connector. Locate the appropriate switch for manual or automatic transmitions and disconnect the switch at the connector and insert the wire into the connector to bypass the saftey switch and turn the ignition switch to the start position. If the light turns on there was a problem with the saftey switch, if not then it is the ignition switch.
CHECK YOUR IGNITION SWITCH UNDER STERRING COLUMN LARGE PURPLE WIRE WITH TEST LIGHT SHOULD LIGHT UP WHEN IN THE START POSITION, IF NOT CHECK YOUR WIRING FUSEABLE LINKS NEAR BATTERY? USE TEST LIHGT ON S WIRE AT STARTER WHILE TRYING TO START ? POWER MEANS Bad starter GOOD LUCK
This could be a bad battery, wiring problem, neutral safety switch or ignition switch. Check wire going into neutral saftey switch for voltage while in crank position. If you have voltage replace neutral saftey switch if not replace ignition switch. Thank you and make sure to rate me. Thanks
