The Truman Doctrine arose from a speech delivered by President Truman before a joint session of Congress on March 12, 1947.
Positive First. When installing a mower battery, always connect the positive cable first. The positive cable is red. It attaches to the battery terminal post marked with a plus sign, the letter P or the word POS. Attach the negative cable last. The negative cable is black.
Do you hook up the positive or negative wire first on a battery? Always hook up the red or positive cable first, otherwise you could cause a short between the battery and the car through your wrench. Ths of course could cause an explosion oâ¦r other problems.
