Question about 1986 Ford F 250

1 Answer

About 6 months ago I parked my vehicle and when a mechanic came to look at it the battery terminals were connected in error and it sparked my relay. I have replaced the relay and the battery but the vehicle still will not turn over.

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

How to jump start a vehicle safely


You have a dead battery and need a jump start. There is the right way and the wrong way to accomplish a jump start safely. Because of the potentially severe hazards due to improper use of jumper cables it must be done correctly. Auto batteries contain Sulphuric Acid which can blind you, or at the very least burn your skin. Also auto batteries vent off Hydrogen Gas which is highly explosive even from the slightest spark. Because of this danger it is critical to attach the jumper cables in a precise sequence. 1. Park the vehicle with the GOOD battery close to the vehicle with the BAD battery but do not let the vehicle touch each other. Make sure the cables are not routed so as to touch any moving parts, such as a fan blade. 2. Attach the jumper cable Positive + terminal to the GOOD battery Positive + terminal. 3. Attach the other end of the jumper cable Positive + terminal to the BAD battery Positive + terminal. 4. Attach the Negative - jumper cable terminal to the GOOD battery Negative - terminal. 5. Attach the last jumper cable Negative - terminal to a heavy metal ground part of the engine and NOT to the dead battery Negative - terminal. Reason being this last connection will cause a spark, and you do not want a spark next to the battery where it could ignite the Hydrogen. 6. If the engine of the donor vehicle with the good battery was not left running, start the engine and let it run for 2-3 minutes to put a charge in the bad battery. 7. Start the vehicle with the BAD battery and then remove the jumper cables from the batteries in the exact opposite order you installed them.

Do you know how your starting system works ? Do you know about the starter relay ? All power comes to an through the starter relay . The park neutral safety switch is on the transmission. VEHICLE RELAYS Testing from the relay base If you have a anti-theft system problem the engine computer - PCM will not let the starter engage . Go to www.bbbind.com for a free wiring diagram of the starter circuit on your vehicle .

Could I run a electric fuel pump on my 1998 Cadillac deville?


if it did not have an electric fuel before then the installation of an electric pump is a relatively easy process. If you have an electric pump already fitted but it has failed then remove it and install the new pump in its place. Take care to check all wires, fuses and relays and any pressure sensors for correct operation. Remove and blank of the opening for any mechanical pump on the engine
For new installation select an easily accessible place under the vehicle that can be protected from flying rocks and road debris. Run a power wire (red colour) from the run side of the ignition switch to the relay ( to be fitted ) near the battery or in the engine bay. Run this wire through an inline fuse close to the ignition switch to protect the circuit. attach to a coil actuation terminal of the relay.( look at the base of the relay for terminal identification. Run a black wire from the other side of the coil actuation pin on the relay to earth. Normally the same bolt that mounts the relay. Run a red wire capable of carrying 20 amps directly from the battery terminal through an inline fuse ( close to the terminal) to a power pin on the relay. Run another red wire from the outlet power pin on the relay to the electric pump. . Run an earth wire from the pump to earth.
This is a basic electric circuit for the installation of the pump. If there is a requirement for a pressure regulator or pressure sensor to control the pressure or pump operation , that control wire will be connected in series into the wire from the ignition switch so that when the pressure is reached then it breaks the circuit to the relay from the ign. switch and the pump will stop operation until the circuit is again completed. When the ignition switch is off there will be no power for the pump

2002 Ford F150 Supercrew - Electrical problem! Help!


dk mak r

As a retired electrical engineer this intrigues me. If you were my neighbor I would put an ammeter in series with the batteery lead to see just how much current is being drawn by the "mystery" load.

When you disconnect or hook up the battery can you see any sparks when the cable touches the battery terminal?

If the battery can get run down over night that is a significant drain.

If there is some sign of spark when you connect/disconnect the battery lead try the following.
Selectively remove a fuse in the fuse panel, (starting with the larger fuses, 15A, 20A) and then connect the battery terminal and see if you still have a spark.

Hope this helps Good luck Loringh
