Airwolf MCT

I recently purchased a pre-owned Daystate Airwolf MCT and am having issues with the electronics. AOA replaced the battery 2 weeks ago and it worked flawlessly. Trying to be proactive I charged the rifle for the 16 hours to reach 100%, now it won’t turn on. I have attempted to charge (again 16 hours each try) 1. rifle key off safety on 2. key off safety off 3. key on safety on 4. key on safety off and nothing has worked. I checked the connection and all appears fine. When plugging in the rifle it says IP voltage good and goes from 0% to 100% but still won’t function. Anyone have some insight?
 
AOA should have the work under warranty. But I know it's a pain to send it back again. However, anything you do to it (if still under original factory warranty) could void the warranty. With that said:

CAUTION:: the capacitor on the circuit board has a very high Volt/Amps charge. Normally, if you want to check the circuit board board, disconnect the battery and let it discharge for about 8 hrs. If you know how to discharge the battery faster, fine, but do it safely.

Turn the key ON. Check all connections, especially where the battery connects to the circuit board.

Try to remove the battery and measure it with a voltmeter to see if it's charged, With the battery removed, use the Ohm-meter to check if all wires to and from the battery are intact. If you have an amp-meter and know how to measure amps (do not short circuit for more than a second or so) see if you have at least 200-400mAh in the battery to see if the charging circuit even works,.

Try a 9V "radio" battery (make sure connecting the right polarity to the circuitboard. It should turn on. 

Going further to see why there is no power or not charging may require some know-how of circuitcircuit boards.
 
great advice fe75. thanks for helping us wolf owners.. do have one your self as well?

I have an MVT in .22 (with built-in chrono). It's a 2012 model, I am the second owner. Had AOA replace the board and battery (for some extraorbitant amount) back in 2013 because it was "forgetting" the velocity settings at times. Bought the heliboard for it this year but did not install it yet. Albeit I have the Impact and the Crown, the Daystate is still special for me because of the technical "marvels". 
 
Thanks for the input! I think I will send it back to AOA and have a pro fix it. Electrical work has never been appealing to me, I should have trusted my gut and stayed away from the Airwolf.

The Daystate Airwolfs IMHO are the Cadillacs of airguns, but because of the electronics there are also in their own category. They were well ahead of their time when first released and I think that with better design many of their innovations (electronically-controlled valve, pressure sensors, chrono, etc) could be used routinely in airguns in the future.
