• Check the battery voltage to make sure it is not discharged below 11 volts.
• Check the negative battery cable to see if it has been securely tightened back on the battery.
• Check the inline fuse located near the battery to see if it is plugged in completely and not blown.
• Check the multi-pin connectors at the back of the radio and at the amplifi er chassis to make sure they
are plugged all the way in.
