Rotate the hand wheel towards you on the furthest right of your Singer 1507 machine . This should take the lever up and you should be able to thread it then.

there are no speakers fuses on this model it only shows relays so your probable couse is your left channel went bad specially if you like to play it loud and for long periods of time ( I recomend that you have it repaired by a profesional ) good lock ,, I have the service manual in case you need it

Hope this is what you are searching for.

I scanned my manual and uploaded it to a file sharing site here is the link to the file:

I only scanned in the English pages, I hope that is not a problem.

Because the sound is only faint says to me that the power amp that controls the left channel is faulty. You need to look at the device(s) on the heatsink and probably replace them.

According to the owner's manual, it means that the battery voltage is low. Page 13:

If it indicates that you have an open shield ground, read through the following page. It will show you how to test the shield ground connection of your head unit..

The MRV-1507 is a two channel amplifier, below I've pasted important info from the manual:

Battery Lead (Sold Separately)
Be sure to add a 80 amp fuse as close as possible
to the battery’s positive (+) terminal. This fuse will
protect your vehicle’s electrical system in case of a
short circuit. If you need to extend this lead, the wire
gauge should be AWG8 or larger.
