Starter problem maybe solenoid which is the only relay for starter. If it won,t turn over try this have a buddy get under the starter with a hammer and somebody else turn the ignition key on and hold it while the buddy taps the center of the starter if it starts up that means the bendex in the is bad.Buy new starter.If it does nothing replace solenoid on the starter.

Where is the location of my starter relay ********* fuse on a 2003 Chrysler Sebring sedan


WARNING: CHECK TO ENSURE THAT THE TRANSMISSION IS IN THE PARK/NEUTRAL POSITION WITH THE PARKING BRAKE APPLIED.

RELAY TEST
The starter relay is located in the Power Distribution Center (PDC) in the engine compartment. Refer to the PDC label for relay identification and location.

Remove the starter relay from the PDC as described to perform the following tests:
  1. A relay in the de-energized position should have continuity between terminals 87A and 30, and no continuity between terminals 87 and 30. If OK, go to Step 2. If not OK, replace the faulty relay.
  2. Resistance between terminals 85 and 86 (electromagnet) should be 75 ±5 ohms . If OK, go to Step 3. If not OK, replace the faulty relay.
  3. Connect a battery B+ lead to terminals 86 and a ground lead to terminal 85 to energize the relay. The relay should click. Also test for continuity between terminals 30 and 87, and no continuity between terminals 87A and 30. If OK, refer to Relay Circuit Test procedure. If not OK, replace the faulty relay.
RELAY CIRCUIT TEST
  1. The relay common feed terminal cavity (30) is connected to battery voltage and should be hot at all times. If OK, go to Step 2. If not OK, repair the open circuit to the PDC fuse as required.
  2. The relay normally closed terminal (87A) is connected to terminal 30 in the de-energized position, but is not used for this application. Go to Step 3.
  3. The relay normally open terminal (87) is connected to the common feed terminal (30) in the energized position. This terminal supplies battery voltage to the starter solenoid field coils. There should be continuity between the cavity for relay terminal 87 and the starter solenoid terminal at all times. If OK, go to Step 4. If not OK, repair the open circuit to the starter solenoid as required.
  4. The coil battery terminal (86) is connected to the electromagnet in the relay. It is energized when the ignition switch is held in the Start position and the clutch pedal is depressed (manual trans). Check for battery voltage at the cavity for relay terminal 86 with the ignition switch in the Start position and the clutch pedal is depressed (manual trans), and no voltage when the ignition switch is released to the ON position. If OK, go to Step 5. If not OK, check for an open or short circuit to the ignition switch and repair, if required. If the circuit to the ignition switch is OK, see the Ignition Switch Test procedure.
  5. The coil ground terminal (85) is connected to the electromagnet in the relay. It is grounded through the transmission range sensor only when the gearshift selector lever is in the Park or Neutral positions. Check for continuity to ground at the cavity for relay terminal 85. If not OK with an automatic transmission, check for an open or short circuit to the transmission range sensor and repair. It is grounded by the PCM if the conditions are right to start the car. For automatic trans. cars the PCM must see Park Neutral switch and near zero engine rpm. For manual trans. cars the PCM only needs to see near zero engine rpm. To diagnose the Park Neutral switch of the trans range sensor refer to the transaxle section for more information. Check for continuity to ground while the ignition switch is in the start position. If not OK and the vehicle has an automatic trans. verify Park Neutral switch operation. If that checks OK check for continuity between PCM and the terminal 85. Repair open circuit as required. If OK, the PCM may be defective

Rear wiper comes on all the time


Remove the rear wiper relay. The relay works just like a fuel pump relay or any other relay.
Here is example of your relay system and how to test it: Remove the relay and turn the ignition switch on and the rear wiper should not operate. If the motor works with the relay out then seek out a priest as the motor is haunted. To test the circuit do the following:
Bypass the relay with a piece of wire, (preferably fused). This means: Remove the relay and put the piece of wire in place of terminal 30 and 87 in the cavity where the relay lives. Even if you don't use a fuse all you are doing is giving the wiper motor the same voltage it would be getting if the relay was closed. All electrical diagnoses should come from the relay. It gives you the input and output for the accessory. The input is 12v hot on terminal 30. This usually this is constant hot wire from the main buss line on the fuse box. The 87 terminal goes to the fan itself so that the output of this terminal will be a grounded motor waiting for voltage. The 86 wire on this relay is normally fed through the fuse box via the appropriate fuse and gets voltage when the ignition is turned on. The 85 terminal on the relay is the field ground and energizes the relay. This wire comes from the switch. When the rear wiper switch is turned on it sends ground the relay terminal 85 which closes the points of the relay and allow power to travel from the 30 terminal to the 87 terminal. This gives power from the 30 terminal to the appliance at the other end of the 87 terminal. The grounded rear window motor receives this power, begins to spin and operate the wiper. By the way relays have a failure rate of about .015% so the problem probably isn't the relay itself.Joe

Headlights, interior lights and radio not working on 1989 corvette. checked fuses and they seem to be ok.


If a good visual inspection showed you nothing like a broken, pinched or cracked wire. Check your ignition relay to see if it is good. You can use a 9 volt battery with some wire and touch the wire to the battery then to terminal 85 & 86 on the relay. If you hear it switching it is good. The relay should be under the hood in the fuse block terminal. Something I seen in the past with the same situation on the same vehicle was water in the passenger side tail light. This causeed the ignition switch to short out and changing it fixed the issues. If your relays and fuses are good and you would know that for sure because you tested them with a test light or ohm meter than I would go after the ignition switch. Unfortunatly if you don't know what your doing and it is a wiring issue you may not figure it out. There are a number of things that could cause this issue. Not working could mean the lights are flickering and you can here clicking. I'm assuming the vehicle starts. More detail could help diagnose the root cause.

1998 dodge ram won,t start off key


make sure the starter is wired properly... you would be surprised how many people forget where the little wire from the solenoid goes.

I have a 1982 dodge ram w150 318 4 speed when i turn the key i lose everything let me start from the beginning my truck started up then died then when I went to restart I heard a thunk then nothing last...


What happens when you turn the key to on? Do the warning lights and gauges come on? Turning the key to start, do the lights and gauges stay on? Just nothing at the starter?

Or does power just shut off when you turn the key to start, everything goes out, no warning lights or gauges? Then check cables, battery terminals, grounds for clean tight connections. There is a problem between the battery and the ignition switch.

If the switch still receives and sends power out (to the dash, for one) but start circuit is not working (from battery to ignition switch to clutch switch to starter relay to starter solenoid to starter to ground-and back to battery), then here's where we at: with key off, use a small screwdriver and short the big cable at starter to the starter solenoid small wire connection, or use a small jumper wire to do the same-battery cable at starter to the small wire connection on the starter solenoid. Starter motor should spin and crank engine. Does it? If so, start checking the start wire out of ignition switch for power when key is held in start. If you have a clutch switch, check for power in with key in start. Should have battery voltage to the clutch switch with key held in start. Keep checking the start wire along the start circuit. Not sure how the start relay is wired into the circuit, would have to see a diagram, but if you pull the relay out and use a test light or multi meter, could check for power on the terminals where relay plugs in. Key off, should have one terminal that is hot. With key held in start, at least one other terminal should also be hot. This would be the start wire out of ignition switch sending a signal to the relay.
Good luck, hope you find it. Sorry I don't have a wiring diagram to help you more.

How can you tell if inertia switch has trip


1. Check fuse 9 (15 amp) of the Battery Junction Box (BJB) to verify it has battery power even with the key off and that it is not missing or making poor contact to its fuse holder.

2. If the fuse checks to be OK, swap the R1 (fuel pump) relay with the R3 (A/C clutch) relay and recheck to see if the car starts indicating a defective relay.

3. If the car will not start, check terminal 3 of the R1 relay to verify it indicates battery power with the key off from the #9 fuse.

4. With the key in the Run position, terminal 1 of the relay should indicate battery power from the PCM power relay.

5. Check terminal 2 of the relay to verify it indicates to be a constant ground to the relay.

6. Installing a jumper wire between terminals 3 and 5 of the relay should provide power back to the inertia switch and then on to the Fuel Pump Driver Module (FPDM).

No fuel replaced fuel pump replaced fuelpump relay


check to see if there getting signal from the switch to the relay... on the relay terminals (4) there should be 1 constant power , 1 constant ground,1 signal wire from ignition switch with key in the on position (usually a ground signal) , and 1 feed wire to the pump.. make sure you have all the appropriate powers and grounds ..
