ABSTRACT OF THE DISCLOSURE An inductor alternator of the type used in a motor vehicle is combined with throttle control apparatus having a vacuum diaphragm that is communicable via a solenoid operated vacuum valve with the intake manifold of the vehicle engine and is operated thereby to actuate linkage connecting the diaphragm to the throttle of the engine carburetor. A function switch selects one of two operating modes, the first providing a regulated do voltage output for battery charging and the second providing an unregulated do voltage output that varies directly with engine running speed and which is suitable for arc welding, battery boosting or powering small resistive appliances, floodlights and the like. In the first mode the vehicle's battery is connected to the do output of the alternator via a solenoid switch but is disconnected in the second mode to prevent damage by an overvoltage. In the second mode, the output voltage is available at either a polarized receptacle or via a pair of welding cables. A local switch actuates the vacuum valve to increase engine speed in the second mode to obtain a fixed output voltage suitable for appliance operation whereas a remote control switch on a welding rod holder runs up engine speed to develop a welding voltage only for as long as the switch is held closed. When released, the engine speed drops to a preset minimum, thereby economizing on fuel consumption.
