I went out and took readings on my 97. I believe the alternators are the same. Battery out is the lug on the back. I checked it with the engine off no key in ignition, then I started it and took measurements again. While the glow plugs were on the battery read 11.7 After glow plugs cut off 14.5...
I think the problem with the FSV normally comes from the fuel pickup in the tank falling apart and the bits of plastic/nylon cause problems in the valve.
Your 11,000 GVW is total maximum loaded weight for your truck. Your truck probably has a curb weight of around 7,000 (you need to weigh it) so your carrying capacity would be 4,000. The GCVR is 16,000 with 3.55 gears and 20,000 with 4.10 gears. If your truck is loaded to capacity of 11,000 your...
The voltage difference you‘re seeing from the tester at autozone and the voltage on your truck is most likely the difference in load placed on the alternator. As load goes up voltage goes down. The load at autozone was probably less than the actual load on your truck. Your alternator will get...
This may interest you. Your alternator is probably 60 to 70 amp output. If you do the 3g upgrade if your alternator needs replacing you pick up almost 100% amperage output. Then you’ll see about 14.4 volts charging with everything running.
Turn everything on and check your voltage, if it’s still 13.2 it’s good but on the low side. Let it run long enough for the glow plugs to turn off before checking voltage.
