Even the speedometer, which is best known of all, is sometimes misread and misunderstood. Take the matter of speed alone. When the speedometer shows the driver stepping on wit and registers around 60 or 70 miles an hour, the usual driver will boast about the mileage shown on the dial as though he had actually made it.

At the 10,000-mile points, the oil filter, gas filter and air cleaner might need cleaning or replacing. They should be checked by a com- petent mechanie. Then again, at every 10,000 miles, the spark plugs might be ready for replacement. the valves ground and the cylinders scraped of carbon.

TESTS STRAIN ON WHEEL"

Taking a running start, Ralph Hepburn, noted auto racer, leaped two feet in the air over railroad tracks in Cleveland, recently and landed without damage to the car or the new type of steering wheel he was testing. It's the solid steel wheel used, for some time on racing cars and now for the first time on a passenger car. The car was a Studebaker.

Headlight Bulbs Burn "Out.

Question I am having trou ble with the burning out of head- light bulbs on my car, both of

them giving out at the same time. The generator is charging at about 8 to 10 amperes. I have examined the wiring for short-circuits, "but can find. none. What do you think is wrong?

"%

Answer: Too high generator voltage, probably caused by abnor- mally high resistance somewhere in the charging circuit, is the most likely occasion for this trouble. You better make sure that there je sufficient liquid in each of the cells, that both battery-cable clamps are tight and that their contact surfaces are perfectly clean and chat the connexions at the ammeter and elsewhere between the gener- ator and battery are not loose dirty. The recommended charging current for this car is 15 amperes at a 25 m.p.h. speed and the fact that your generator is passing but 10 amperes, rather indicates that there is too much resistance in the charging circuit. Short-circuited wiring does not cause bulbs to burn out.

Hill Climbing Suggestions. Question: What is the best procedure to follow when at- tempting to take a hill on high gear?

2

Answer: Unless a car has surplus of power or unless the road surface is too rough to warrant it, the car should be speeded up just before the hill is reached and kept at a good rate of speed by gradual- ly opening the throttle. If ignition
