That shouldn't be much, but you must plan for the day the horn sticks and the resistor gets really hot. I'll remove it tomorrow maybe. Perhaps that'swhy I like cars in the 20's and 30's. Do you have a buddy with a 6 volt battery and perhaps a amp meter? (1) compression test WHY because if the compression is bad working on ignition or carburetion is a waste of time and money, (2) ignition test WHY because if the ignition is faulty, nothing you do to the fuel system will help, (3) fuel delivery system test WHY because if there is no fuel in the carburetor, the carburetor doesn't work. A #1815 bulb in a suitable lampholder (purchased at Radio Shack) works fine. Schematics of the simple 12V to 6V converter circuits are discussed below. I can take my old 6v battery and run power direct to the horn and it works, but not with the 6v from the reducer. 3) Bad float. Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Save on Voltage Regulators, Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- You may also like. "@type": "Person", Personal and professional opinion - if I owned a 1949 or 1950 Oldsmobile driver OR showcar, it would have the Carter correct for the year. Your 6 volt horn will be fine connected to the 12 volt system. If so, what do they go to? I do not know why, but it seems all the new made Corvair mechanical fuel pumps have springs that put out 5 to 7 psi! Got enough fittings and a gauge to get a pressure reading? The rest of the truck is 12volt but the heater was still 6 volt. Which may be will apply number 7806 provides the voltage of 6 volts. The old system could carry more amps. The 12 volt battery should smooth out the DC going into the converter as noted in the 5th bullet. Variants of the 2G were still being used by new cars in the 1980's. ). . If the pressure is a little wrong, it can change the float level, leading to a whole bunch of tail chasing because the height setting in the book assumed the original fuel pressure. This one is self explanatory. Price Not Available. It will be louder then the 6 volt. Use a three-terminal regulator or DCDC converter. You can use this voltage reducer to operate 6 volt DC motors and fans on 12 volt DC. Devide the rating in watts by 6 volts and that gives you the amps that the light draws at 6 volts. id idn't know any such thing existed.
