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 best practice to disconnect the ground cable and perform an out - of - vehicle test to ensure safety and accurate results. Option A is incorrect as you don't multiply findings by the number of batteries in this context. Option C is an incorrect connection method for testing. Option D is incorrect as disconnecting the positive cable alone is not the standard procedure; the ground cable should be disconnected first.

Answer:

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