JL 500/1 draws .5a without remote

[mnhiphop101]

This amp draws current without the remote. The amp seems power up fine still tho. Any ideas?

Did you pull the cover and check to see if the main or low-voltage supplies were operating with no remote?

I'm assuming that you don't have it on signal-sensing.

Can i use the main ground to check the low voltage supply?
When I flip it to signal sensing it fully turns on.
It's completely out of the case.

 

[Perry Babin]

Yes,

It seems like the main ps is partially activating. Enough to give me +73v dc across the pos. & neg. Speaker terminals.
I've posted a pic of the wave on the drain of the ps

Copy and paste the following list and fill in the blanks. If there is no blank space after the colon, add one between the colon and the numbers you enter. It makes it much easier to read.

DCV on all terminals of the LM324 on the preamp board?

Check R627. It not marked in all revisions but it's near the jumper 'cop6's designation marking near the 3525 end of the PS driver board.

It's reading exactly 4.7ohms

DC voltage on each side of it (B+ and ground connected)?
