If you yourself replaced the alternator and battery, I would recheck your work. I am not questioning your ability, but make sure that all your connections are clean and tight. The next step if everything is o.k. with the connections, is to take the car into almost any auto parts store, and have the battery tested "under load". Even a new battery can be defective. Good luck!!
Electrical system dilemma...HELP
New member Hello All, I recently purchased a 2016 versa from a rental car agency whose policy is to use the vehicle to 45,000 miles then sell. So I have it now and it has 126,000+. The alternator went down the other day so I replaced alternator along with battery. Now the car will sometimes start with a boost and sometimes it will crank right up no boost. I have no dash lights just the beep of key in ignition. Now I put a SCAN tool on it and the only read I get is EOT (engine oil temp) sensor. I'm stumped and thinking about replacing the ECM/PCM the brain anyone who could point me in the right direction would be greatly appreciated. Thanks in advance guys and gals

Thank you for taking the time to respond, Yes I double and triple checked the connections and ground points the fusible link at the Positive terminal (120A) is separated/blown I believe it's A on the diagram. But having it checked to see what's what will keep u posted
Sounds like to me somebody did not disconnect battery first thing and shorted something out. 120 amp fuses don't just blow for nothing. Or the old alt blew out to do it.
I'm confused more so than normal.. Are you the only owner since it was a rental? Are you 100% sure the replacement alternator is good? I've seen folks go through 3-4 aftermarket alternators until they found one that works. A lot of times a dealer parts counter unit is just troublesome reman unit as well.New member Hello All, I recently purchased a 2016 versa from a rental car agency whose policy is to use the vehicle to 45,000 miles then sell.

Aside from that, could the vehicle have a parasitic draw? For troubleshooting, you could unhook the battery just while the vehicle sits to see if it will crank over full force next time you hook it back up.
I have similar problem with my 2015 Versa Note SV, pretty much since I bought it used in 2016.
My car has an electrical leak for the last year or two. I've had the battery, alternator and starter all tested, and mechanic says they're great.
If I turn off the car, but continue listening to the radio for a couple minutes (not high draw amplification, just some interview on the radio), car won't start.
If I leave headlights on for 30 seconds after turning off car, car won't start. Then I jump start my car with another car or a battery pack jumper cable, and it starts right up.
This might happen a couple or few days in a row, and then no problem at all for a few days or even several weeks.
A tech recently put an ac/dc clamp meter around my battery cable, and saw that 1.3A was flowing through it, with ALL lights, switches, fans, radio, etc turned off.
Anyone know any solution to all this?
Thanks!
Ted

Do that same test but start yanking fuses out one by one. When you hit the problem circuit the current use will drop way back narrowing the problem area greatly. Then you focus on that.
