EMPI's 12 to 6 Volt Resistor drops 12 volt power to 6 volts so that older 6 volt accessories such as wiper motors or radios can be used when you've converted your VW Beetle, Karmann Ghia, Bus or Type 3 to 12 volts. The old wires are thicker because they carried more amps but less volts. It limits voltage to coil when using 12-volt battery. Heavy Duty Electric 12 Volt To 6 Volt Reducer Resistor, For Fans/Motors. 2 terminal style, reduces voltage to distributor points, 1.5 OHMS of res 12 V/2 mps = 6 ohms total resistance from the battery throught the resistor and through the light. In over 100000 miles I put on the truck after the conversion I never had an issue with the gas gauge not working right. Steiner Tractor Parts sells new parts for old tractors. I do not think my 6 volt horn on a 12 volt system is loud by todays standards. Calculate this current, and plug it into this formula: R= (12â5)/I to get the required resistance. Converting your 6-volt Ford flathead car, truck, or tractor to 12 volts does not require replacing everything associated with the electrical and engine circuits. All times are UTC [ DST] 12 volt to 6 volt dropping resistor : Page 1 of 2 [ 31 posts ] Go to page 1, 2 Next Previous topic | Next topic : Does anyone know where to buy the specific resistor to do this, and the ID brand and part number for such a resistor? and dissipate 8 watts (14 volts (battery) - 6 volts (radio) x 1 amp). You will need a "Runtz" for each 6 volt electric gauge on your car. If the item draws 10 amps at 7.5 volts- - - -it's using 75 watts of power. As the current increases above 2 amps, you'll have to use a switching regulator or your car will have a nice built-in electric heater. 261 sold. Restore your vintage tractor with new aftermarket parts for many classic tractor brands. This is why you are able to use the same wiring and mechanical switches in a 12-volt system as in a 6-volt system. true for wiring: because 6-volt systems require higher amperage to operate, wiring within such a system essentially is two times larger than that required for 12-volt systems. ... 1951 Gauges use 6 volt with a 12 volt system. Includes clamp on bracket." The 12 to 6 voltage drop is wired inline, typically after the fuse box, on the wire that supplies the 6 volt accessory. "Runtz" transistorized 12v to 6v reducers allow you to use your original 6 volt electronic devices (like gauges) on a vehicle that has been converted to 12 volts. 12/6/2 Amp 12 Volt Battery Charger. Where Vout = (Z2/(Z1+Z2))*Vin However, many vehicle owners decide to convert from 6 volts to 12 volts in order to be able to use more readily available electrical components. Replaces ABC366, S43243. Product Line : Clore Automotive ... this item may be purchased online to be shipped to home or may be purchased in person by visiting a NAPA store. Its a way to divide the 12 volt alternator voltage to approx 6 volts across the bulb, leaving 6 or so for the rest of the car. 12 volt resistor relay - Can anyone tell me exactly how a 12 volt resistor relay works? 4 product ratings - Electrical Resistor for 12 Volt to 6 Volt Fits Ford 9N 9-N 8N 8-N NAA Jubilee Tr. Top Rated Seller Top Rated Seller. Antique Radio Forums Index » Category » Electrical/Mechanical Repair and Restoration. I did the usual changing of the coil & bulbs but I never put a resistor on the gas gauge (never occurred to me that I needed to). Lets say that the lamp is 12 watts,then 12W/6V = 2amps. With a fully staffed technical help department, helpful customer service reps, great product photos, helpful installation and repair videos, we are ready to help you restore your first antique tractor or your one hundredth. Hopefully I didn't overload anyone with too much electrical talk. Mounts through 7/16" diameter hole. If youâve got an electrical device that operates on 6 volts, connecting it to a 12-volt battery will break it. Screw type terminals. Vintage Tube Radio Reducer 12 volts to 6 volts Multi gauge reducer Oil Gas temp Gauge 12 to 6 volt MGR1 12 volt to 6 Volt Electric Window Seat & BW Overdrive reducer without relay Heavy Duty 100 Watt Heater & Defroster Motor Reducer 12 volt to 6 volts View unanswered posts | View active topics. 13.8v â 6.8v = 7v, so you need to drop 7 volts across the resistor at 3 amps A 12 volt system allows you to use modern automotive electrical accessories (lights, tools, some implements) which are not available in a 6 volt version. Between the 1930âs and the mid 1950âs, 6 volt electrical systems were the norm. Can you put a 6 volt battery in there for this to charge, then t ï»¿ h ï»¿ e horn will work. Soâ¦ Youâve got 13.8v, but you want 6.8v on a device that draws 3 amps. For example, the original 6-volt motor requiring ten amps of electrical current would only need five amps of electrical current to run at the same speed. Your 12 volt system actually is at about 13.8v with the motor running and you want the radio to get about 6.8 volts, which is roughly what the system voltage would be on a running 6 volt system. Buy It Now. -AC Delco part # F610 and F611 -Napa part # VT6187 (Echlin) This may be the best option. 1.5 ohm resistance for 4 amp maximum load. 6v/2 amps =3 ohms for the light. Flashlight 12v to 6v reducer works with up to 10 amps of continuous current draw. Part # : SOR 4512. Devide the rating in watts by 6 volts and that gives you the amps that the light draws at 6 volts. Since the car is set up for 6 volts, I recommend using the original 6 volt generator configuration. The resistor needs to drop 7.25 Volts, and the accessory needs to run on the other half. DA Plug Try NAPA or Patrick's has a real nice one; 12 volt coil AC Delco 1#12337166 (not internally resisted) 12 volt coil resistor 1 #12336832 or NAPA ICR13 or standard Ignition VRC 604; 12 volt horn relay (2) 7 inch headlights; Fuel Gauge Reducer NAPA IR4 or NCA #2143 (3) voltage reducers for accessories (1 for heater, 2 for radio) NAPA VT6187 Tiny #682902 Sun Oct 03 2010 08:56 PM. If the item is not in stock at your local store, then your store associates can order the item for you. This would give the starter motor 6.5 volts with 22 amps of current and 143 Watts, which is pretty close to the stock 6 volt system. Simple! There are voltage reducers that are inexpensive to buy.
