Question

if you are testing batteries connected in parallel, you should: a) multiply your findings by the number of batteries installed b) disconnect the ground cable and perform the out - of - vehicle test c) connect the positive lead from the tester to the first battery positive terminal, then connect the negative lead to the last battery d) disconnect the positive cable and perform the out - of - vehicle test

Explanation:

When testing batteries connected in parallel, it is standard practice to disconnect the ground cable and perform an out - of - vehicle test to ensure accurate results and safety. Option A is incorrect as multiplying findings by the number of batteries is not a typical testing method. Option C is wrong because the correct way is not to connect positive to the first and negative to the last in this manner. Option D is incorrect as disconnecting the positive cable is not the standard procedure; the ground cable is usually the one to disconnect first for safety and proper testing.

Answer:

B. disconnect the ground cable and perform the out - of - vehicle test
