1993 Ford Ranger charging system problems

It depends on the spark plugs that have been used. Some are pre gapped, some have three preset side electrodes around the edge. Gapping spark plugs is not as critical as the old days due to modern CDI ignition systems which give a much larger spark and huge improvements in spark plug technology.

Was the a/c compressor running when you got this reading?

The 2.3 (vin A) cylinder head can be purchassed at a salvage yard for around $200 used.
or you can try a 'speed shop' (they rebuild heads) in the yellow pages.

Hi Closet, I think the problem will be with the voltage regulator or a defective alternator. I believe it will be easier to fit a service exchange unit. That will mean removing the alternator from the vehicle. Remove the keys from the ignition. I believe its a good idea to make sketches all the way through the procedure, that way you'll know what goes where. Disconnect the battery and remove the negative. Loosen the alternator tensioner until the belt can be removed. Disconnect the electrical connections. Remove the through bolt under the alternator and then remove the top bolt. Remove the alternator from the bracket. Fitting is the reverse procedure. Make sure the belt is correctly tightened, and you should be away. Regards Johngee10

Have a compression test done ,and look for a vacuum leak near the cylinder,like a vacuum hose or intake gasket.If the compression test shows a fluctuation between the 3 and 4 cylinder,then the head gasket would need to be replaced.

Check your rear end to see if you have a sensor like in this video, if so it could solve some issues. The video describes items all going out around the same time. Its based on a 2 wheel drive but who knows you might have the same sensor in the same location. This is a shot in the dark, but who knows it might help or point you in the right direction.

Replace your oil pressure sending unit. Usually costs about $10.

TEST B: BATTERY VOLTAGE OUT OF RANGE - DTC B1676
1. Check if vehicle has been jump started within past 2 weeks. If vehicle has been jump started, ABS is
okay. If vehicle has not been jump started, go to next step.
2. Using DVOM, measure voltage between positive and negative battery terminals. If voltage is 9-19 volts,
go to next step. If voltage is not 9-19 volts, diagnose charging system. See appropriate GENERATORS
article in STARTING & CHARGING SYSTEMS.
3. Turn ignition off. Disconnect 25-pin ABS control module. Install EEC-IV 60-pin Breakout Box (014-
00322). Turn ignition on. Measure voltage between breakout box terminal No. 20 and ground. If voltage
is more than 10 volts, go to next step. If voltage is less than 10 volts, repair Light Blue/Pink wire between
ABS control module and instrument panel fuse panel.
4. Turn ignition off. Measure voltage between breakout box terminal No. 25 and ground. If voltage is
greater than 10 volts, go to next step. If voltage is less than 10 volts, repair Red wire between ABS
control module and power distribution box/engine compartment fuse box.
5. Measure voltage between breakout box terminal No. 9 and ground. If voltage is greater than 10 volts, go
to next step. If voltage is less than 10 volts, repair Yellow/Light Green wire between ABS control module
and power distribution box/engine compartment fuse box.
6. Measure resistance between breakout box terminal No. 8 and ground. Also, measure resistance between
breakout box terminal No. 24 and ground. If both resistance measurements are less than 5 ohms, replace
ABS control module and repeat self-test. If either resistance measurement is greater than 5 ohms, repair
suspect Black wire between ABS control module and ground distribution.
NOTE: DTC B1676 will set if vehicle has been jump started.
