I have an old Solus Pro EES316. I was working on a 2005 Saturn Aura 3.5L when the cars battery went kapoot. I hooked up a jump box and all the while my scanner was connected. Ever since this event years ago the scanner says no comm. On every vehicle regardless of key. I bought a new cable new keys k17 k20 nothing makes a difference. No comm on all vehicles except random features with k20 occasionally. Is there an internal fuse I may have fried or did I damage the motherboard may be? I did a restore and no dice. I have a pro level Autel now but would love to fix this old scanner I loved it. Thanks everyone for any advice. I have usa and euro software and all the keys for both but all are useless to me at this point.
