1999 Dodge durango 5.9 starter clicks but wont turn over replaced starter/battery good as well as the starter relays

Hi Mark
Sounds like you are doing all the right things.
We used to Load Test a Starter Motor by putting it in a Large Vice and connecting a known good battery with solid fat jumper leads.
When the solenoid throws the cog forward to engage we would use a 2 by 4 block of wood levered against the cog to try and stop the starter from spinning. The wood burns up under load but it quickly proves the Starter is functioning under load. Without using the engine.
Also you could try removing the spark plugs on the engine to allow the compression to escape. Make sure NO sparks around to ignite any fuel vapor.
The engine should spin over easily like this and you can hear & see if anything is binding up.
Hope this Helps!
Good luck!

Sounds like you have a bad starter solenoid. You are probably going to need a new starter. You could get under the vehicle to make sure you have 12 volts to the starter to verify. Also make sure battery connections and ground wire is good

Have you checked the battery? If the battery is fine you may want to check your relays. I hope this helps you out.

Check your battery voltage and connections. If they are good, disconnect the battery for 5 minutes and try again.

1999 Dodge Caravan wont start new battery,new starter,nothing but clicks when key is turned on continues to click when key is off could this be the relay switch checked power to starter starter is energized

may work may not...on older cars when the starter went bad and the car wouldn't start you could tap the starter with a long screwdriver or hammer lightly and the solenoid would engage and start the car but you need to get it home or to shop cause it wouldn't work again..if you try this and the starter engages then the starter needs to be replaced if you haven't already tried..if the lights are flashing when you try to start the vehicle then o would say its prob a malfunctioning alarm system..try to diengage it by pulling fuse for alarm..don't know if you can though..check the starter...good luck

It sounds like your starter solenoid (relay) is failing. The clicking is a classic symptom. It's time to have it replaced.

A starter solenoid (or starter relay) is the part of an automobile which relays a large electric current to the starter motor, which in turn sets the engine in motion .In many vehicles the solenoid also engages the starter pinion with the ring gear of the engine.

The starter solenoid receives a large electric current from the car battery and a small electric current from the ignition switch. When the ignition switch is turned on, a small electric current is sent to the starter solenoid. This causes the starter solenoid to close a pair of heavy contacts, thus relaying a large electric current to the starter motor, which in turn sets the engine in motion. The starter motor is an electric motor that initiates piston motion in a car's internal combustion engine before it can power itself.

Will the radio play. It could be just the battery. If battery is ok, it could be solenoid on the starter.

If your positive and negative terminals are clean, both ends... not just battery, you should hear your starter relay click each time you turn the ignition key to 'start'. If no click, check connections to relay, If still no click, relay may be the problem. Assuming your battery or batteries are charged and you only here the click of the relay and no starter action, good chance the starter solenoid is in poor condidtion, or history. An indication of this problem is the starter would work intermittently and finally quit working.
Its an easy cheap fix. First disconnect you positive cable on the battery so you don't fry yourself or anything expensive. Remove the starter. Undo usually four bolts that hold the starter case together and pull it apart. Its always a good idea to pay attention how it came apart so you put it back together the same way.
The starter solenoid is just an electrical contact switch that conducts high amperage to the starter motor during engine start. The contacts in this switch burn out over time. When you pull the starter housing apart, you will see that the solinoid contact switch is installed within the hump on the side of the starter housing. You will quickly see if the solinoid contacts are burnt or damaged. Most auto parts stores have a whole collection of contacts. I paid 3.85 Canadian for a set that didn't quite match the set in my 95 dodge cummins. 20 minutes of filing saved me the $600.00 my buddies were paying . "Rebuilt' my starter about 5 years ago... and starts every time. Hope this helps someone out.

on the starter there is a big battery cable and a small signal. wire connect a test light to the signal wire and try to crank the engine. if the light comes on then you will need a starter. be sure you have good connections first good luck.bye the way the light should only be on when you hold the key in crank pos.if the light is on all the time you are on the wrong wire.
