That tells me you have a voltage output problem! You do not have a battery problem. Do the 2,500rpm test regardless. You need to run the test necessary to isolate the alternator or get a second opinion on your alternators output. If your alternator's output is good I'm not impressed with 14 volts at the alternator, you have a wiring or regulator problem.
Huh?? 14v at alt is fine(Ford says 14.4), but if that 14v isn't being supplied to the battery, it generally means the fuse link between batt and alt is open...
Make sure the "ALT" light on the instrument panel is working...If it does not light when you turn the key to the ON position. The bulb is probably burned out. If the light does not work...Your charging system wont either...The resistance from the bulb is what excites the alternator to start charging.
Krazy Comet may be close to the solution to your charging issue, i.e.. a fuse link or some other wiring issue, assuming the voltage regulator is doing its job. I further agree with Krazy Comet on the 14v issue. Your alternator appears to be operating in good order, no second opinion required.
That's mostly hearsay, at least in Ford charging systems, the 15 ohm resistor that parallels the bulb is what excites the alt... Without a resistor, the bulb probably won't draw enough current to do so... If both were bad(resistor & bulb) that could defiantly be a cause... This is a earlier diagram without the fuse link but is essentially same otherwise(up till '70 they were not used, which is a possible fire hazard)... The fuse link is part of the black & orange wire between alt and battery... http://1bad6t.com/Maverick/repair/engine_repair_02.html#c
Remember that there are two fusible links. One goes from the main harness to the solenoid and the other comes straight off the alternator battery terminal. Since the car runs the fusible link to the main harness is working. Using a test light you can follow the fusible link to the battery terminal on the alternator and make sure there is a complete circuit. If you have power all the way to the alternator then you can run the engine and jump field terminal at the voltage regulator plug (Just for a Short Time as it will run the voltage to the max) and see if you get a higher voltage at the battery.
ok i checked the fusible link wire with a light tester and nothing so i pulled the wire harness out and peeled the electrical tape off and one spot on the solid black fusible link wire is soft and weak
charge up the battery throw a spare one int eh trunk fill up your tank and come on over well get it fixed for ya
My fusible link keeps blowing and i took my alt in and learned that its putting out 65 amps, since ive been working on my brothers gt for the last few weeks i noticed his fusible link wire is the same gauge as mine so i took his alt in and his to is putting out 65 amps, so my question is why is my link blowing but his isnt even we have the same setup. Also ive noticed my alt light doesnt turn on so maybe thats the problem.
