I didn't have the batt charger on the battery so those voltages were from straight off the battery for the rectangle part, (btw it has no part # it was scratched off not by me tho)

You need to determine why pins 8 and 11 0f the 494 don't have 12v (approximately) on them.

As a side note, my anti-virus alerted me to a potential problem (faceboax.a) on that site (car audio classifieds) and two other sites (that scan domains for threats) list it as suspicious. If you're a regular visitor of that site, you may want to ask the moderators to see if the site has been hacked.

Follow the traces from pin 11 or 8 on the PC board back to the parts. It should be a part that ties to + voltage.

Read the basic amp repair from Perry's sig line.

Since this company is belly up, can you get the schematic from the fellow on CACO?
