I have a 96 Ford ranger, 2.3 liter. We changed out motor to 2.5 liter and wiring harness and ECM. The alternator isn't charging and keeps blowing fuse. Any suggestions?

Https://ibb.co/vD3tDf8 Click on the link, wiring diagram for your generator, 96 ranger--2.3L. Which fuse is blowing? As you can see, the generator bat terminal has a fusible link on that circuit. See the charge indicator circuit, that is excite voltage w/o that, the generator won't charge.

SOURCE: ford ranger truck overheating

I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

SOURCE: 1991 ford ranger 3.0 eec relay fuse keeps blowing fuel good no sp

I understand that there is a relay box under the hood with 3 relays. Which is which I don't know. However if you are blowing the fuse TO the ecc relay, then the relay must be bad. This relay controls the spark.

The coils are fired by the ECM, check all the wires to the ECM from the coils and make sure the signal is getting through and you don't have a wiring issue at the engine firewall connector on the driver side firewall.

talk with an auto electrician as there are now many alternators that are controlled by the ECM ( voltage regulator is in the ECM) 14.5 volts -14.38 volts is good voltage control so the problem may not be the regulator at all
problem could be a shorting diode in the circuit or other problems not connected to either the alternator or regulator such as wiring shorting out , bad connections etc
may even be an ECM problem

What your problem sounds like is a short in the engine harness. When the engine is under load it will rock slightly this can cause wires to rub. If the right wire rubs ground it will blow out your fuse. Follow your harness from the fire wall to the engine and look very closely for any rubbing of the wire loom.
