What is the DC voltage on the amp terminals?
With your multimeter set to DC volts, the black meter probe on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) and the head unit on (so the amp will have remote voltage applied), touch the red probe alternately to the B+ and remote terminals of the amp.

The amp appears to have blown the fuses again. Check them but don't replace them. Post what you find.
The fuses are good. The fuse holder in the amp had a brass piece that looked like it had popped out. I tried to fix it and no luck
there are 4 and the brass that snaps into the back of the fuse holder wasnt snapped it. That brass piece goes to the circuit board. All fuses are ok. Tried to fix fuse holder but no luck
A single fuse holder shouldn't cause the amp to completely lose power. Can you post a photo of the area you're describing?
Here is what I am describing. The brass piece thats on the back of the black fuse holder; where the arrow is pointing.
Do i just measure by putting the probe on the brass bar going from the fuse holder to the circuit board? Right by where it states the name (Like CP6)?
With the black probe on the same point and remote voltage applied, are you still getting less than 5v to all pins of the 494?
I checked all the voltages again and this is what I got:
1-.5v
2-4.93v
3-.07v
4-.51v
5-1.47v
6-3.39v
7-.02v
8-13.11v
9-6.2v
10-6.2v
11-13.94v
12-12.89v
13-4.94v
14-4.94v
15-4.94v
16-1.27v
1-.5v
2-4.93v
3-.07v
4-.51v
5-1.47v
6-3.39v
7-.02v
8-13.11v
9-6.2v
10-6.2v
11-13.94v
12-12.89v
13-4.94v
14-4.94v
15-4.94v
16-1.27v
OK, with the black meter probe on one of the non-bridging speaker terminals, what's the DC voltage on the center leg of the large output transistors?
Don't allow the meter probe to short to the clamps on the transistors.

Virtually all of the components clamped to the heatsink are transistors. The large transistors are the output transistors.
