Why won't my Jensen MPR420 Receiver turn on?
If your Jensen Receiver isn't powering on, there are several potential causes. First, the yellow wire might not be connected properly or may have incorrect voltage; check the connections to ensure the voltage is between 11 and 16VDC. Second, the black wire might not be connected to ground; verify this connection. Finally, the fuse may have blown, in which case you should replace it.
What to do if my Jensen Receiver keeps blowing fuses?
If your Jensen Receiver is blowing fuses, it could be due to a few reasons. A yellow or red wire might be touching the chassis ground; check for any pinched wires. Alternatively, speaker wires might be touching the chassis ground, so inspect those for pinches as well. Lastly, the fuse might have an incorrect rating; make sure you are using a fuse with the correct rating.
