I have repaired my Bose 321 Home Theater System 3 times. I am wondering if I have an inverter problem. How can I isolate. Bose has been very good performing no cost repairs.

Seadaddler, I think what MattRob means is...
- He uses a Bose 321 Entertainment system on his boat,
- He uses an on-board inverter to power it (the inverter isn't part of the Bose system),
- The Bose system has quit working 3 times,
- The Bose dealer repairs it (under warranty, which won't last forever...), and
- He thinks the quality of the electricity from the inverter may be what's causing the Bose system to fail.
MattRob, Not sure how to isolate trouble with inverters, or what the power requirements for the Bose system are. What kind of inverter do you have aboard?

Jon's question is the beginning of the "detective work" work you'll need to do to help us to help you. Was it a factory installed inverter or did you or the PO install it. What brand and model. What wattage or amperage draw is your Bose system?
Hunter 38 Inverter Test Update
The responses to my question moved me to action.
1. The Bose 123 System was factory installed, 300 watt system
2. Bose repaired the out of warranty system 3 times at no cost (on a 2005 H38)
3. I need to insure the problem is not the inverter
4. Hunter Customer Service (always helpful) provided me with the inverter make/model; Sinergex PureSine600. Note: My boat is currently out of state, not accessible by me until mid October.
5. I found Sinergex on line and requested from them "how to test system to spec". Or, any other suggestions they might have.
6. I had previously tested the output voltage with a multimeter, as OK.

Inverter
Do you have another inverter charger on board and if so try using that inverter.
I saw a Hunter 38 and it had a smaller inverter for the TV and Boss system and a larger inverter /charger for the rest of the boat systems so that is where I ask trying the other inverter.

If the inverter is a qualty pure sine wave inverter it should not be causing problems unless it is too small for the job or being taxed by start up loads while running the Bose. If however it is a typical MSW / modified sine wave inverter the Bose system may not like it... The Bose system may also not like the humid environment.. It would be much better to know what components Bose has been replacing when it fails...
Just reviewed specs
They rate power requirement at 300 watts.
I think the inverter may be borderline, and clipping its output at higher volumes.
This will definitely cause the input switching power to have grief, and could damage it.
If this is a modified sine wave, (square wave that approximates sine wave through a series of amplitude steps), then I could see this being overheated & damaged.
A certain way to exclude this is to just run the 321 directly from shore power.
You won't have tunes from it while you're sailing though. Don't know if this is an issue for you.
Also,,, is this inverter also powering your TV? If so, then for sure you are way over the limit on power requirement

"the inverter does not drive the TV (shore power only). Sinergex said have tested multiple inverters returned by Hunter, all OK. Waiting on response from Bose, specific failures, board or component issues, seeking answers from their reliability engineering. So far, they recognize it is much to their benefit to resolve this as mine. Next step, as you suggested, are the two systems (Bose and Sinergex) compatible. Bose engineering would have to tell me. Appreciate everyone's input.
My 2005 Hunter 38 came with a Prosine 1000watt pure sine wave inverter to run the Bose 321 system (requiring 300watts) and the flat screen TV.
I suspect your inverter is not intermittent, e.g., they usually either work producing full sine wave output or the don't.
I'd be more suspect of the "Entertainment" breaker in the hunter wiring system.
The 12 volt Entertainment breaker on the main electrical panel is a 40 amp breaker. It is wired to a distribution panel found under the navigation table seat. This (gray) panel has 6 additional circuit breakers on it named R1 through R6. R1, R2, and R3 take that 40 amp circuit and split it up to run "entertainment" circuits into the V berth, the aft cabin and the main cabin's pure sine wave inverter. Make sure that none of these "R" breakers is tripped paying close attention to R1.
The reference circuit diagram is very hard to follow, but it is on page 64A2 of the Hunter Owner's Manual. If R1 is tripped, the pure sine wave inverter won't get 12 Volts and won't run the Bose 321 system.
I suspect you're getting free warrantee service from Bose, because nothing is wrong with the unit.
If you have shore power available, simply run an extension cord (from a shore power outlet) under the port settee where the pure sine wave inverter is located. Disconnect the Bose 321 110volt plug from the inverter and plug it into the extension cord. If that works, your Bose system is fine.
(Note: the 321 media center controller is mounted on the wall and connects to the subwoofer under the settee. It's just the subwoofer that plugs into the inverter.)
Next, get a 110 volt appliance -- a desk lamp, a vacuum cleaner, etc. -- and plug it into the inverter. If the breakers (Main entertainment and all the "R" breakers are all set) and the appliance doesn't work, then suspect the inverter.
Hope this helps,
Rob

Rob, I have never reset the "R" breakers and the Bose System has worked upon previous re-installations. I will not be back on the boat until mid-Oct, will follow thru on your circuitry then.
Rob, installed repaired Bose 321 System, all works O.K. Talked to Bose trying to understand failure. Their response was, "if it fails again, we'll replace the whole system". Both Bose and ProSine have been very supportive throughout this process. Your suggestions also greatly appreciated!
