Question about 1988 Ford F 250

3 Answers

I have a 1988 F250 7.3 liter Diesel for which I recently replaced the battery cables. Unfortunately I do not remember the correct connections from and to the positive terminal of the battery. A wiring diagram or a photo under the hood of another similar vehicle showing the correct connections would be helpful.

    There are about four separate wire connections that need to be connected correctly. There is a fairly heavy wire that runs along the starter cable that connects to the solenoid. There are two light wires which I believe are to be connected to the bolt on the anode clamp. And there is a relatively heavy short cable that runs from the battery to one of two relatively large bolt connectors fastened on the right inside fender. The problem is what are the right connections to those two bolts? An under the hood photo of a working 88 F250 would be very helpful in solving the problem.

The problem is what are the right connections to those two bolts? Does the heavy short cable connect to one of them and the solenoid cable to other? If so which one? Or do both connect to the same bolt? And if so which one? I tried one connection combination but when I turned on the ignition switch there was a continuous clicking sound and when I turned the switch to the starter position there was no response. An under the hood photo of a working 88 F250 or a wiring diagram would be very helpful in solving the problem.

    I have a 1988 F250 7.3 liter Diesel for which I recently replaced the battery cables. Unfortunately I do not remember the correct connections of the ancillary cables from and to the positive terminal of the battery on the right side of the vehicle. There are two small diameter wires which I believe hook directly to the bolt that clamps the cable connector to the positive terminal of the battery. But there is a larger short cable that goes from the positive terminal to one of two bolts fastened on the inside right fender wall. Another wire follows the main cable that leads to the starter. That cable activates the solenoid. The problem is to which of the two bolts does the solenoid cable connect and to which does the short heavier cable connect? A wiring diagram or a photo under the hood of another similar vehicle showing the correct connections would be helpful.

The cable that comes from the radiator side (and runs in front of the radiator) goes to the positive of the battery.(if you're not sure follow the cable, if it connects to the starter then it is the positive, if it connects to the body it is the negative.) You battery positive may be marked by a "+" stamped into the casing or red plastic ring around the battery terminal. The negative will be black or stamped " -"
In the unlikely event that there are no markings on the battery you will need a voltmeter. Make sure the red lead is inserted into the positve terminal on the meter. If you connect the meter and get a positive reading the red lead is on the positive terminal of the battery, else it is on the negative.
Connect the positive cable to the positive of the battery and the negative to the other terminal.

    I know all that information. That's not the problem. I know very well how to determine positive and negative terminals and their connections for both batteries. The problem is how to properly connect the smaller ancillary cables from and to the positive post of the battery on the right side of the vehicle. Please read carefully the details of my description of the problem.

Just to help, the positive battery cable goes to the starter and the negative battery cable goes to the negatively grounded body.

There might be an additional long bolt for the positive terminal for other accessories, I'm not sure.

How many terminal ends do you have?

1988 Chevy Tahoe Starter going out. Need to replace


Generally starters have 2 or 3 bolts and a thick wire coming from the battery and other miscellaneous connections.

You did not specify a vehicle that was on my list, i.e. 1988 Chevy Tahoe.

However, it may be similar to a Suburban R10:
REMOVAL & INSTALLATION The following is a general procedure for all trucks covered in this manual, and may vary slightly depending on model and series.
  1. Disconnect the negative battery cable at the battery.
  2. Raise and support the vehicle.
  3. Disconnect and tag all wires at the solenoid terminal. NOTE: Reinstall all nuts as soon as they are removed, since the thread sizes are different.
  4. Remove the front bracket from the starter and the mounting bolts. On engines with a solenoid heat shield, remove the front bracket upper bolt and detach the bracket from the starter. Fig. 1: Starter mounting location — 4.8L engines 84903021.gif
    Fig. 2: Starter mounting location — 4.3L and 5.0L engines 84903022.gif
    Fig. 3: Starter mounts — 5.7L and 7.4L engines 84903023.gif

  5. Remove the front bracket bolt or nut. Lower the starter, front end first, then remove the unit from the truck. To install:
  6. Position the starter and tighten all bolts as follows: R/V Series:
    • Thru-bolts: 40 ft. lbs. (54 Nm)
    • Bracket bolt: 30 ft. lbs. (41 Nm)
    • Nut (gas): 11 ft. lbs. (15 Nm)
    • Nut (diesel): 90 inch lbs. (10 Nm)
    C/K Series:
    • Thru-bolts: 35 ft. lbs. (45 Nm)
    • Bracket bolt (diesel): 24 ft. lbs. (33 Nm)
    • Nut (diesel): 75 inch lbs. (8.5 Nm)
  7. Reconnect all wires. Fig. 4: Disconnect the negative battery cable 87982p25.jpg
    Fig. 5: Remove the starter retaining bolts 87982p30.jpg
    Fig. 6: Remove the starter from the vehicle 87982p31.jpg

Fig. 16: Exploded view of the starter mounting-2.5L engine
  1. Disconnect the solenoid leads at their solenoid terminals. If necessary, tag then to avoid confusion when re-installing.

Fig. 17: Attach the starter wire connector to the terminals as shown-V6 and V8 engines


2e59350.jpg
Fig. 18: To remove the starter, unbolt the mounting hardware shown-V6 and V8 engines


On 4WD Dakota models with the V6 engine, the starter is removed from above. On these models you will have to disconnect the steering gear and position the shaft out of the way to gain working clearance.
  1. Remove the starter attachment bolts and withdraw the starter from the engine flywheel housing. On some models with automatic transmissions, the oil cooler tube bracket will interfere with the starter removal. In this case, remove the starter attachment bolts, slide the cooler tube bracket off the stud, and then withdraw the starter.

Fig. 19: When detached, pull the starter away from the engine and remove it from the vehicle-2WD Dakota model shown

To install:

  1. Be sure that the starter and flywheel housing mating surfaces are free of dirt and oil to make a good electrical contact.
1547e44.jpg
Fig. 20: Install the starter motor on the 4WD Dakota from above as shown
  1. Slide the starter in place, secure using the bolts and washers removed. Tighten the bolts to 50 ft. lbs. (68 Nm). Connect wires and battery cable end at the starter.
  2. If removed for clearance, reconnect the steering column shaft.
  3. Secure the oil cooler bracket if equipped. Connect the negative battery cable on the battery.
When tightening the mounting bolt and nut on the starter, hold the starter away from the engine for the correct alignment.

Diesel Engines

  1. Disconnect the negative battery cable.
  2. Raise the truck and support it safely on jackstands.
  3. Disconnect and label the wires at the starter motor.
  4. Remove the attaching bolt, nut and washer, then lift the starter and solenoid assembly from the engine.
To install:
  1. Before installing the starter motor, be sure the mounting surface on the drive end housing and the flywheel housing are clean, to ensure good electrical contact.
  2. When tightening the attaching bolt and nut, hold the starter away from the engine to ensure the proper alignment. Tighten the bolts to 32 ft. lbs. (43 Nm).
  3. Attach the wiring at the starter. Tighten the solenoid connection to 44 inch lbs. (5 Nm). Tighten the battery cable at the starter motor to 16 ft. lbs. (22 Nm).
  4. Attach the negative battery cable.
SOLENOID REPLACEMENT
Chrysler Corp. for 1989-91 models did provide replaceable solenoids for the starter motors covered by this information. However since 1992, the manufacturer no longer recommends replacement of individual components, even if the later unit has the same part number of a formerly serviceable unit. Chrysler now simply calls for replacement of the entire starter assembly if the solenoid is found faulty.

88 s10 wiring problem


if you have a 4.3 liter the wire from the positive post on the battery should go to starter and to the post with 10mm nut on the back of the alternator with a 2nd wire that goes to your ignition coil. ignition coil wire should have a fusible link in the line.
