Batteries Die overnight, new alternator, batteries test good, no parasitic draws.
I apologize in advanced for what will probably be a stupid question and the long winded way i ask it.
I have a 2006 F250 6.0L with next to no performance mods besides a suncoast transmission and SCT Livewire Tuner. Also i recently just had a Omega 2-way remote starter installed.
Saturday morning when i tried to start it with the remote starter it turned over very very slowly a couple times and then quit. I then got in the truck and tried to start it and it turned over very slow a couple of times and then just started to click. Well i left it and came back to it in the afternoon and tried to start it again and it turned over slower than normal but faster than it did in the morning and i was able to get it to start. Sunday morning when i came out to drive it, it did the same thing. I came back a couple hours later and tried again and it started so I took it to autozone to have the batteries, starter, and alternator tested. The batteries and starter all showed good but the guy said my alternator wasnt charging enough. After the short drive from my house to autozone (~8 minutes) the truck started up like a champ after being shut off. It seems to just be a problem when the truck is cold, after running for a littleO while the truck will start right back up but if its been sitting overnight it does not want to start. Also i have no new electronics so there wouldnt be any new power drains that didnt used to be there.
so i guess my question would be is it really the alternator? Also the guy at autozone said it might have dual alternators? if that is the case then which one do i change? Is there a way for me to test it myself to see if its bad? How hard are they to change? I have changed a couple of alternators in gas cars but never in a diesel truck. Also what brand should i go with?
