All question need 'year make model' as the first 3 words. Then you have 10,000 categories to choose from listed by 'make year model'. With that we can help you.

The negative from the battery goes to the chassis within 12" of the battery. The live is red and goes to the fuse box and the starter. The big red wire on the starter is the positive and the smaller black wires are grounds.

Clicking when you try and start means either that there is not enough electricity getting through to the starter or the starter is defective,
If the battery is charged and you're getting nothing on the dash as well, that means that something in the connection from the battery to the rest of the car is not conducting the electricity. Check your battery terminals for corrosion and the battery wires for damage, Check your fuse panel for blown fuses. Ask the shop that replaced your starter,

Could be the starter relay but , could also be the park neutral safety switch , test by moving the gear selector to neutral . If it starts then more then likely the PNP switch is bad . Viewing wiring diagrams to see what all is involved in starter operation . Reading factory service info. for starter operation would be good too . The engine computer (PCM/ECM) probably energizes the starter relay . Free wiring diagrams here http://www.bbbind.com/free-tsb Enter vehicle info. year , make , model an engine . Under system click on engine , then under subsystem click on starting . Click the search button , then the blue link . Looking at the wiring diagram it just so happens there is no starter relay . Ignition switch sends battery voltage through the PNP directly to the starter solenoid . Could be the main battery cable , voltage drop testing will show if that is the problem .

Checking starter circuit

You put the positive battery cable on the starter? I don't know how you could get that wrong, so the battery is hot at the starter there, and as soon as the small wire on the starter solenoid activates the solenoid (it should with the key in start, the only time that small wire has power on it) then the battery is connected directly to the starter motor and the engine should crank.


Find a wiring diagram of the start circuit for your vehicle, and trace the circuit from the start position of the ignition switch to the starter solenoid. There may be a starter relay involved, there surely will be a park/neutral safety switch or a manual clutch switch depending on the transmission you have, and there may be a theft deterrent module that is involved or maybe not. You will need a wiring diagram to diagnose it and a voltmeter would be very helpful. Post back with year, make, model, and engine size- I might be able to look at a wiring diagram, or send you a link.

-the wires are not correctly re-installed for the starter.
- u may need wiring diagram
Did you take pictures before you took it apart, or did you tag wires before unconnecting them.

I don't have a diagram but the starter always has a connection to the battery. Follow battery connections and you will find the starter. It is always on the opposite side of the engine that the belts are on.

You don't need a diagram.Lift the car disconnect the battery and the wires to the starter solenoid remove the starter bolts and check the shims placement.Replacement starter is reverse to what is listed in removal

Some starter solenoids are mounted on the fender near the battery and some are on the starter itself.

Typically the ones mounted on the fender have two larger posts and one smaller post. For the larger posts: One connects strait to the positive post on the battery. The other connects strait to the starter. The smaller post connects to the neutral safety switch which connects to the start position of the ignition switch. Here is a diagram. Make sure the solenoid is grounded good.

For the solenoid that is mounted on the starter: Connect the positive post of the battery to the large post on the starter. Connect smaller neutral safety switch/ignition switch wire to the smaller post.


Here is a diagram if you have both solenoids

Don't forget to hook backup any other wires that were hooked to the positive side of battery/solenoid like alternator wire etc.

Your best diagram is the starter itself...make notes on where wires are attached and what you removed from where. Always remove the positive cable from battery before you begin and never allow wires on one starter terminal to touch ones from adjacent terminal when you replace them.
Remember...your starter turns the engine so it can start...it does not start your engine. Always have your battery charged and load tested to avoid changing the starter because the battery is bad.
