Did you pull any error codes (Diagnostic Trouble Codes)?

1. Remove right side saddlebag and side cover if so equipped. Remove protective plug from data link connector. Other models will be under the seat.

2. To activate the diagnostic feature,follow these steps.
a. Create diagnostic test wire or use a female spade clip which will bridge the two terminals perfectly.
b. Install diagnostic test wire/clip across Terminals 1 and 2 on the data link connector, they are marked.
c. Turn Ignition/Light Key Switch to IGNITION and wait approximately 10 seconds (4 seconds lamp ON, 6 seconds lamp OFF) for check engine lamp to start flashing.

3. All trouble codes are sent out as a series of flashes. To retrieve the first digit of the trouble code simply observe the number of times the lamp flashes.
a. The lamp will then flash one or more times to indicate the first digit of the trouble code.
b. The length of time the lamp is illuminated and the length of time in which it is off are each about 0.5 second in duration.

4. The second digit follows:
a. Following the transmission of the first digit, there is a 1.2 second pause in which the lamp is off.
b. The lamp will then flash one or more times to indicate the second digit of the trouble code. Count the number of times the lamp flashes to retrieve the second digit.

5. If more than one trouble code is sent:
a. Following transmission of the second digit of the first code, there is a 3 second pause in which the lamp is off.
b. Once all codes have been sent, the data string is repeated. When you have recorded the same trouble code twice, it is an indication that the transmission has been restarted and that all trouble codes have been retrieved.

IMPORTANT NOTE ..If diagnostic test wire is installed across Pins 1 and 2 on connector in lieu of a Scanalyzer, the ECM is placed in a diagnostic test mode and the engine will start. The test wire must be removed from the data connector and the ignition switch turned OFF or the check engine lamp will continue to flash codes. A historic trouble code resides in the memory of the ECM until the code is cleared by use of the Scanalyzer or a total of 50 trips has elapsed. A "trip" consists of a start and run cycle, the run cycle lasting at least 30 seconds. After the 50 trip retention period, the trouble code is automatically erased from memory (that is, assuming no subsequent faults of the same type are detected in that period). The numbers after the 'historic' or 'current' is the speedo code number, but without the electrical diagnostics manual you're not going to know what they mean.

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.

Possible that there is a short and is much related to the power section or the output driver. You can isolate the outputs , remove the speakers and check to see the power drain current using a series clamp meter. If the current drain is high then the power section must be checked.

Some manufacturers tend to fudge the numbers and throw around the 'peak' output power as continuous and it isn't. Peak (or surge) is the power a generator will handle as starting current (for example) for a motor and can be 120-140% of the actual continuous power.
Check you owner's manual, find the detailed specs which will normally contain the maximum continuous current rating. If it is listed separately for 120 and 220 (240) volts look for separate current ratings for each output.
By multiplying the current(s) times the output voltages you can find the total resistive output into a purely resistive load such as an electric heater.
For example: 120VAC X 20 A=2400 watts. If other outputs are available such as 220VAC, multiply its current rating: 10A. or 2200 watts Adding those two results 2400 2200=4600 watts will give you the rated power of a unit.
You can also recognize stupid power claims if the engine's horsepower is given. One (US) HP = ~746 watts. Since no generator is 100% efficient, its a fair rule of thumb to guesstimate the available electrical power at ~70% of the engine's rating (although, this is often also wildly optimistic). 10 HP X .7= ~746 X 7 or a bit over 5,000 watts.
