First start needs a jump

Had this problem back a couple months ago. I replaced both batteries, both ground cables, GPR, CPS. Problem went away. Now it's back again. Had batteries load tested,and alt. tested. Alt was charging 14.2 volts, with 62 amps. What next? Any ideas? Starts up perfect with a jump, then starts fine the rest of the day. ???????

Disconnect your battery's when you park it for the night then reconnect them in the morning and see if it will start. If it does start you have a parasitic draw. Also you can try to pull your battery's when you park it and have them tested the next day and see if letting them sit for a while will make difference in the load test.

X2.

Are you sure they did a load test on the alternator? 62 amps is what was being drawn, or what it is capable of producing? If that is its max capacity under load test, I would say the alt is on its way out.

I had this problem last week. the jumper cable that connects the positive terminals on the batteries was pretty badly corroded. replaced it and sprayed everything with corrosion preventative, no problems.
