I used a PM GM one wire 130 amp before I bought the the MSD, and after it died at DW (five years later)I bought a used PM 130 amp from a friend of the O'reily auto parts manger in Topeka. with this I can start the engine with the alternator off and then flick the switch and the alternator starts charging but then when I turn the switch off doesn't turn off the alternator as now the regulator is supplying voltage to the field circuit. Just crimp on a female spade terminal plug to this wire and push it on. The two-wire connector houses the exciter wire, which is responsible for turning off the in-dash light. It is a GM alternator of the type that has a 2-wire electrical connector which plugs into the body of the alternator (I don't know what kind of alternator you refer to that as. When using our high output alternators you must upgrade this cable to retain warranty coverage. An example of an alternator incorrectly tightened to its mounting brackets (see pic below). The wire to excite the charge circuit should be ignition power and run through a bulb in the dash. remove, clean and tighten battery post connections to check for alternator output,use a volt meter or multi-tester set to 50 Volts DC,w/ tester on battery terminals it should read 12 volts W/ engine off;13 to. The original wire would be best. The drawback of this arrangement is that if the warning lamp burns out or the "exciter" wire is disconnected, no current reaches the field windings and the alternator will not generate power. 200 matches. I am using a 1G Ford Alternator. They are pre-terminated with the ignition input wire and the voltage-sensing wire. I have inherited this car that has been in the family since 1978. They are also known as synchronous generators. You can probably use the "alternator power" wire of the new harness for the B terminal on the regulator. Alternator Exciter Wiring I have the Ron Francis 5. Once the alternator is rotating the field current will be. Read more about a serpentine belt. Instead of upgrading it, add a 2nd wire (#6 or #4 gauge) to it, and run that from the B+ stud on the alternator over to the B+ (battery) side of the fender mounted starter solenoid. The green wire goes. I have a 2008 f-250 with a 6. alternator and alternator exciter wire, coil, water temperature, and oil pressure. First thing to do, is get a volt meter, and see what charge you have at the battery with the engine running You need 14 volts If not, shut the truck off, and test the green/ red tracer wire to the alternator with the key on/ engine off to see if you have 12 volts That is your exciter wire. I don't have a wiring diagram handy at the moment. I have run one wire alternators in several cars,I always do two things I get two cables like Fords use from the solenoid to the starter which are usually 4 or 6 gauge at most parts houses and run one from the alternator to the POS+ battery post, I run the other cable from the alternator bracket to frame ground. 7L diesel locate the diagram for the momentary switch exciter. The contact owns a 2003 Ford Excursion. When the alternator terminal is at 12v the light goes out. Alternators and generators are two devices which generate electricity.
