Home Theater Questions? Ask a Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, bear with us; re-confirm and post back with the complete model number of the new stereo.
And do you have access to and familiar with a multi-meter?
Can you at least get hold of a test light? ... though a multi-meter is preferable.
Let's go through the basics; a review of the AMB600W wiring:
Can you also please try to temporarily disconnect the red wire? ...and then join it together with the yellow wire to the always available +12V source?
Yes please on the multi-meter.
Post back with the model number when able so that I may post information as to what settings and configurations to use the multi-meter.
The •200 V~ setting is for AC voltages. We would want it to •20 V--- for DC voltage.
And yes, black probe to black wire and red probe to red and then yellow or even if joined together.
We are expecting a reading of around 12 Volts for the AMB600W to work
If not a fuse, then possibly a loose wiring connection or even a switch or even a poor terminal connection.
Is there only a single 12V battery? ...or 2 or 3 tied in series?
"...getting a 13.97 reading..." on both yellow to black and red to black pairing?
Please press the RESET button behind the detachable face plate.
Yes please; it should be wired correctly, then remove the face plate and using a dull pointed object, press on the recessed RESET button.
For test purposes, try simply twisting the red & yellow to the +12 source wire and the black to the ground wire. Use electrical tape to ensure no accidental shorting or grounding of the live wires.
For this test purpose yes; i.e. red and yellow together to the wire of the boat (red?) that provides the +12.
Please re-check the 10A fuse at the back of the AMB600W.
Do you have a spare 12V bulb? The idea is to see if the boat's red wire and the ground wire would be able to power the bulb / light it up.
Try the 12V lamp/bulb to test if the boat's red and ground wire have 'real' power.
The meter gave a residual / ghost 12V reading; no real power.
As posted earlier, please trace the the boat's red wire as well as its ground wire to where they originated from. A likely loose connection, corroded terminal.
