The official 2014 Spark EV service manual is now available for us common folk to purchase. If you're interested in getting a copy, it's Helm item number GMP14SEV and it's currently only available in paper form. I ordered mine at http://www.helminc.com and received it in less than a week.
It's not a light read! I plan to bring mine to Kinko's, have the binding removed, scan it into PDF format, and make a text searchable file out of it. I've done this in the past and it is well worth the few hours extra for tinkerers like me to save time in the long run and have a digital file instead of lugging books around. If anybody is interested in a good method to do the same digitizing with your manuals, let me know. Also, please don't ask, of course I won't be sharing my PDFs! Aside from obvious legal reasons, I also want Helm to sell every copy imaginable to make up for the hassle of GM and Helm making this book available for such a low volume car!
