I changed my cranking batteries and since then starting engine has been harder. It takes a longer cranking time to get the engine to start. Any suggestions.
Half the time, people change out batteries when they actually have a charging problem. I suggest you get it running and perform a charging system check. Also it would be a good idea to perform a voltage drop test through all of the connections such as the ground on the engine, started, and alternator. Many times there is high resistance and it surely messes up the starting, and charging functions.
