My 24 E-ray is having troubles starting. I had the battery tender off for a few weeks and now my car is completely dead. Have tried calling roadside assistance and they have been unable to get car started as well. It is currently stuck in my garage and towing it out is an issue because they don't have enough room on the sides to put it on skates.

Im thinking I may just need to replace the 12v lithium battery in the garage. They tried with the noco boost and still no power. Any suggestions

Thank you

 

Check the sticky in the E-Ray section my friend. Nothing wrong and it's an easy fix.

The 12v battery has a safety on it. Low voltage protection it's like a breaker. It's tripped. To flip it you need a jump box. Direct to battery.

It great article you put together from this ERay owner

 

Thanks for the help. I did purchase the same noco boost pro in the video and had to use the manual override. Car will turn on but will still not start or allow me to put in neutral.

 

If you can get it to turn on, have you tried putting it in shuttle mode so it will move on the EV battery?

 

Weird. Hope you can figure it out. Maybe take a video of whats happening. We can try and help.

 

Just know that I almost freaked out but thankfully cooler heads prevailed and I fought through it. Wanted to save others from going through the hassle. Hopefully it helps anyone using these li ion batteries with the uvp protection.

Chevy could've made an eaiser way to jump direct to the battery. but its not "too bad" to fix.

 

Since the dealer tired the NOCO Booster as you did, why not try what the Owner's Manual states is a viable method and provides power for a long crank, Another fully charged battery as you would jump any car!

From Owner's Manul
Be sure the vehicles are not touching each other.
If they are, it could cause a ground connection you do not want. You would not be able to start the vehicle, and the bad grounding could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set the parking brake firmly on both vehicles involved in the jump start procedure.

3. Turn off the ignition on both vehicles.
Unplug unnecessary accessories plugged
into the accessory power outlet. Turn off
the radio and all lamps that are not
needed. This will avoid sparks and help
save both batteries. And it could save
the radio!
4. Open the hood. See Hood 0 17.
5. Release the four clips for the left and
right outer covers.
6. Release the five clips and remove the
outer cover to access the battery.
7. Locate the battery positive (+) terminal
and remote jump starting negative
(−) post.
8. Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock. The vehicles
could be damaged too.
9. Open the discharged battery positive (+)
terminal trim cover and connect one end
of the positive (+) cable.
10. Do not let the other end of the
positive (+) cable to touch metal.
Connect it to the good battery
positive (+) terminal.
11. Connect one end of the negative (−)
cable to the good battery negative (−)
terminal.
Do not let the other end touch anything
until the next step.
12. Connect the other end of the negative
(−) cable to the remote jump starting
negative (−) post.
13. Start the vehicle with the good battery
and run the engine for at least
four minutes.
14. Try to start the vehicle that had the
discharged battery. If it will not start
after a few tries, it probably needs
service.
Jumper Cable Removal
Reverse the sequence exactly when
removing the jumper cables.
After starting the disabled vehicle and
removing the jumper cables, allow it to idle
for several minutes.
The power windows may need to be
initialized. See “Window Indexing” under
Power Windows 0 29.

Worth a Try!

 

Sorry to learn that you're having battery concerns with your E-Ray. We understand that you're having difficulties getting it moved out of your garage, but if you get a chance and are able to bring it into your preferred Chevrolet dealership, we'd be happy to lend a hand of support through any necessary diagnosis or repairs. Feel free to email us at socialmedia@gm.com with "ATTN: Corvette Forum/24E-Rayyy" in the subject line and we'll be here to assist.

 

"great article you put together from this ERay owner" Again, if a "specialty" version owner, always check to see if there is a Forum section devoted to your model.. All the best!

 

If the battery is coming alive (he didn't say what voltage) the car with the pack attached would start in override mode. The noco boxes are very powerful. If the car isn't starting but getting power it sounds like something else is going on. A video would help greatly. with noco attached etc.

 

Just a thought as a NOCO in good shape may be fine. Can't be sure what was tried was! Fact is you can jump start the car with another car battery. Sure what I would try.

And agree since he got "somethoing" the contacts should have closed. I'd install a charger and seewhat happends.

 

Thank you for the help. I did try getting the car in shuttle mode that does not work.
Currently I am waiting to hear back from the dealership as they are looking to send a technician out.

ButI will post a video once I get my booster charged up
