This was three years ago and I’m still using this damn thing for everything with a 3000 watt inverter. Take the generator and cutout shown and white them out. 4) Connect a minimum 10AWG wire from the “BAT” position of the ignition switch to terminal “S” on the back of the amp gauge. Alternator vs. A true alternator IS a generator: an Alternating Current generator, which is where the term alter-nator comes from. Connect the battery's positive cable to the alternator with a washer and nut. ALTERNATOR FITTING. It is better to connect this new wire directly to the battery cable, and leave the original brown wire to supply the normal amount of power to the rest of the electrical system. I advise to find an old style hand drill; flea markets are often a good source for older tools like this. Best to utilize a deep cycle battery. As its name implies, the 3-wire alternator has three electrical connections to it. So, with minor modifications, the alternator will produce electricity for a home. The alternator is best as a connection point, but if your new wire is nice and big, the starter relay or the battery would be fine. The Epic Center: Convert Lawnmower into Generator, Other Power: Alternator Generator Comparison. The alternator’s positive and ground cables should be sized according to the chart on Page 3. If you are using a Delco 10SI alternator use your 3/8” ratchet and 9/16” socket to remove the existing brackets for the generator from the exhaust manifold. This will invert the AC from the alternator to DC in the inverter. This diagram shows how to wire a Delco (GM) internally regulated 3-wire alternator. You must verify that all required connections are connected to the proper terminal and have the correct voltage in order for the alternator to operate properly. Attach the exciter field tap wire to the 1/4-inch terminal screw on the alternator with a washer and nut. An electrical supply for a small house is usually a 100 amp service but a larger home will require more. Below you will find the most common alternator circuits used on marine applications. Out of pure curiosity and having the parts readily available, I tried it following his every detail. After removing the alternator, cut a length-wise 1-inch slot out of the bottom. However I can say with 100% certainty that a 12v generator system with a battery bank and power inverter can run 110v home electronics reasonably well. Extreme damage to the generator, wiring, ammeter, and regulator (or cutout relay) will result if the battery and generator polarity are not matched. Your email address will not be published. Using 10-gauge wire, to which solderless ring terminals have been installed, connect the output bolt on the back of the alternator to the positive terminal of the battery. Tools (wrenches, drill, drill bits, etc. But… all this seems a duplication of the power-plant sitting in your driveway. The orange wire with the male connection on it goes to the generator light on the dash. Instead, go to a heavy truck supplier for a massive alternator engineered for constant duty. Steve Smith has published articles on a wide range of topics including cars, travel, lifestyle, business, golf, weddings and careers. The way they are set up each inverter runs ONE side of the breaker box. Automotive alternators can supposedly be reconfigured to generate 110v. REMEMBER dc voltage is just as lethal as ac Wiring is really just about as simple as adding one wire from the BAT post on the alternator to the + … The field wire … Oh! This is just information to get you thinking, there is a lot of information on youtube. December 1st, December 2nd, - Ford 6volt Tractor Wiring Diagram. You can also make this connection on the starter solenoid where the positive cable is connected. If using a single larger 110v inverter (4000-5000watt) you will have to split the positive (+) into two leads and wire each side of the breaker box, if using two smaller inverters (2000-3000) run the negative (-) from each to the center buss (common ground buss, there will be bare copper wire bunched up along this buss bar) and then run the positive from each inverter to one side of the box. Bolt the unit on in place of the generator, noting that you have removed two wires from the generator ( a thick one and a thin one.) Thank you for your positive input. This information is intended to show you that it’s possible to do with just a little ingenuity. Many of those people, those who desire to be off the grid, must find ways to power their homes without relying on the power company.

Older house service panels utilize fuses, this is similar to a breaker but when a fuse blows it is done, when a breaker trips you simply turn it all the way to the off position then back to on and service is restored. Plug the sense line housing into the alternator case. … This diagram shows how to wire a Delco (GM) internally regulated 3-wire alternator. This will invert the AC from the alternator to DC in the inverter. If there is a small wire crimped in with the ammeter wiring at the bulkhead (there probably is) you are gonna have to cut it loose and extend to your new circuit and connect it. (tach) wire if needed and other necessary wiring. Weld a four-inch steel pulley to the lawnmower motor shaft using an ARC welder and #3 filler bar. Did you know a car alternator can be turned into a generator with a little know how and persistence? Attach the other end to the positive terminal of the battery. I have a wire going from the screw that holds the regulator on the firewall to the GRD post on the alternator. This 12v system can still run a refrigerator or stove simply by using a step up transformer commonly known as a power inverter or you can use the 12v system to power a 12v motor to turn an entirely independent generator system with a higher voltage output if you can source that free rather than spend several hundred dollars on inverters. Where do you think the power companies get there power? Being self sufficient is becoming more important these days and it’s far better to be so than to rely on someone to come and save you. The inverter will have to be bought unless you happen to know how to make one, like this guy: There are tons of videos on how to do this but I’m not sure I want to try that, I’ll buy an inverter. 2 inverters will only produce 220 in proper phase don’t place 2 inverters as shown you will more than likely destroy both inverters.
