Picked up a ceramic heater at Pep Boys this am; it plugs into the cig lighter and uses 200 watts. Is this going to be a fuse buster ? Will I have to upgrade the fuse ? Any tips ?

Running the car itself doesn't take all that much. Ignition and injection and the injection pump take about 15-20amps. Lights, radio, and heater blower motors can easily consume as much. There's probably 10 amps of spare capacity if you're driving along with the brights on, the radio blaring, the turn signal going, both blowers going, with a turn signal blinking. My 912 has only a 25amp generator on it, but it also has carbs and a mechanical fuel pump. Just turning on the brights and the brake lights at the same time will max it out, which is why they went to a 35amp unit later.
