The Volts claimed a small and yet helpful 57 run first innings lead on day two, before reducing the home side to 118 for five - just 61 runs ahead with five wickets in hand.
The top order once again failed to flourish for the Aces, despite an opening partnership of 50 between Lou Vincent and Tim McIntosh.
However, Vincent's dismissal for 38 triggered a damaging collapse as the next four batsmen went for a combined total of just 42.
Colin Munro (28*) and Craig Cachopa (6*) then came together at the crease to see the rest of the day out. Having put on 377 together in the Aces recent match against the Wellington Firebirds, the pair know they are more than capable of resurrecting the innings.
Ian Butler added two more to his first up effort of five wickets on day one, while Neil Wagner also broke through with a couple of scalps his own.
It backed up the good work done by Aaron Redmond earlier in the day to claim a slender first innings lead.
Redmond played with the upmost patience on his way to 98, spending three and a half hours at the crease and facing 279 balls.
His largest partnership came with co-opener Hamish Rutherford (70), with the pair putting on 103 for the first wicket.
It came to an end in unfortunate circumstances, as Rutherford was run out in the 28th over.
Further contributions were scarce, with Sam Wells the only other one to really get going with 35. Redmond looked to be on his way to triple digits, until he too was gone to leave the Volts 246 for seven.
The tail was cleaned up smartly, as the Aces made sure the deficit would not leave a huge gap for them to negotiate in the next innings.
Much of the good work with the ball came from Dean Bartlett, who picked up five wickets in his 18 overs for 53 runs.
Despite the good bowling effort, the Aces find themselves well and truly behind and will have to show some serious resilience to deny the Volts the points tomorrow.
