This circuit operates the alternator charging lamp indicator. The alternator bracket will also need to be modified and you will need approx two washers to take up the space between the alternator bracket and the alternator. The alternator drive belt must ride straight over the alternator pulley, the water pump pulley and the vibration damper pulley. The same reading should be 12 volts with the engine off. Alternater has been bench tested putting out 70 amps. Trial fit everything, tighten the mounting bolts finger tight until you are sure everything fits nicely without binding.
Use a bolt with metric thread to fasten the adjusting arm to the alternator and just for good measure put a nut on the end where it threads through the alternator. Now would be a good time to replace the battery terminals. We apologize for this inconvenience and encourage you to visit for the latest on new cars, car reviews and news, concept cars and auto show coverage, awards and much more. Loosen and remove accessory drive belts. The adjusting arm may require some grinding to provide clearance between it and the vibration damper.
Take off all the original alternator mount brackets and clean the area you will be working in. . Post Reply after you do what i have posted above. So for me, installing a technologically advanced one wire 85 amp charging system was an easy decision. I not the best on wiring problems.
He put two lights in the gages but the ones that are in the dash idit lights are out. The smaller 45 amp Delco alternator will fit easily on the upper location. Don't know what to do anymore can anyone help with this. Could I have lost the ground when I took the speedo out to repair? If you have a warning light in the dash then that bulb serves as the needed resistance and you should use the non-resistor adapter. The original voltage regulator is removed.
The green wire with brown stripe is paired with an 18 gage yellow wire that connects to the horn relay. If it helps I can call you? A 10 gage wire from the battery post terminal on the alternator to the positive battery cable side of the starter relay will also work. It has two 18 gage leads, a white one blue on the wiring diagram , with solder less crimp connector installed and a red lead about three inches long with a ring connector. I have a externally voltage reg which is on the core support. Click on thumbnail to see larger picture. A 13mm wrench will be needed to tighten the bolts. One is a non-resistor and the other has some resistance built-in it.
We ordered it with a V-belt pulley and included a new charge wire in our order. The installation was extremely simple and we had the new alternator in place after about an hour in the shop. Without adding an aftermarket voltage sensor, the battery warning light will no longer be functional after removing the voltage regulator. Installation should be similar for any 1961 — 1979 F-series truck. The red wire with ring connector connects to the battery post on the alternator, same post as the 10 gage wire running to the positive battery post. Photos by Tommy Lee Byrd. The flange for the tensioning bolt and the alternator bracket are tapped for metric bolts so you will need to get two 8mm bolts with a thread pitch of 1.
I put in new reg, battery is good 12. Another option is to run the alternator charge wire to the starter. There are two different types of conversion adapters. F on the alternator to F on the regulator. I have an external regulator. I on the other hand enjoy my old truck so much that I literally drive it every day. Post Reply My camaro was not charging correctly, it was only showing battery voltage on my volt gauge.
Most will probably come with a pulley for a serpentine belt like mine did so you will have to change over your pulley if you are still using a V-belt. I forgot to tell you when I got the car the horn is still not working all the parts under the horn are gone. For me the answer is simple, this project is in keeping with my philosophy of making my driven daily truck technologically new without sacrificing practical originality. The lower location is cooler. Post Reply i have a test. We carefully traced the wires, as this regulator was originally wired into the horn relay, which acted as a power distribution point. The yellow wire on the alternator diagram is not used in this application.
The red line shows the original shape of the bracket and how much needs to be ground away. The yellow wire operates the horn and it is hot with the ignition on. Doing this will provide a little extra movement of the alternator when you install the belt and it makes things neater. With the belt installed and everything tight, we can install the charge wire on the back of the Powermaster alternator. Lastly, the lower location looks cleaner and provides a less cluttered appearance. Other people say diodes in alternater. We went with a Powermaster 12si-style unit, offering 150 amps and a simple one-wire connection.
Near the regulator is a connector with a 18 gage green wire with brown stripe paired with a yellow16 gage wire. Remove the fan and water pump pulley. If your car has an externally regulated alternator you will need to convert it first. A volt sensor can be added to the new alternator for volt gauge or warning light functionality. Post Reply this is how it's more than likely wired. Use this and go to for more information on converting to an internally regulated alternator.
