Zone 2 won't work

What kind of help were they?
Did they check all fuses?
Take to a repair shop & get
it properly diagnosed & repaired
Google the Codes you got at auto zone,
to see the system with the fault

my guess is that the yamaha has pre-amp outs, most yamaha stuff does, and that is the one you should be using for the main, and hooking up to the onkyo, and letting the yamaha be your zone controler, and the onkyo be your remote amp for your second zone (if your onkyo had pre-amp outs it would work how your trying to do it, but it dont) so exchange there places, and run a pre amp out to any input of your onkyo, and you'll have total volume control of your outside speakers

How are your cable and cd inputs hooked up? Analog connections? Alot of receivers cannot send an audio signal from hdmi inputs to zone 2.

It won't work. Your moped's electrical system won't support that sort of demand.

I would suggest a full synthetic oil, next time & stay with 5W-30
That will be better on start up

I have no idea why it won't start after only changing the oil

I think that was just a coincidence

I just installed a new throttle body ,because the motor has
acted up for 7 months & unknown the battery was failing
as I was diagnosing some odd behaveour

I was using professional scan tool software & when that
went weird I saw the computer module & battery voltages
going down,key on,engine off. So strange things happen
with todays electronics. When your think your on your game
things go to the twylight zone

zone 2 volume can be adjusted by zone2 remote control (small one which came with the unit) or by main remote control if you switch it to zone2 mode. My main rem control has a slide switch i have to put in zone 2 position to operate zone 2 amp.

If your satellite box is connected using a digital cable to the 601 receiver you won't get any sound through zone 2.Zone 2 can process only analogue sound ( inputs ).

Check the starter/solenoid - sounds like either one or both need replacing. If you can get the starter off - you can take it to an Auto Zone or an O'Reilly's to get it tested. I'm not sure of any tests for the solenoid (sometimes it's part of the starter) - some cars also have a starter relay switch. If that's the problems - it's usually cheap & easy to replace.

have the same model. just got it to work. but, struggling with one part. here's the scoop. 1. Plug your second zone speakers into the SURR BACK/AMP ASSIGN speaker outputs on the unit. 2. You need to "amp assign" the speakers to zone 2 by pressing AMP, MENU, select SPEAKER SETUP, AMP ASSIGN and scroll to ZONE 2 - this will force the sound to the speakers that you plugged in. 3 - Turn on Zone 2 (press Z2, press ON button on remote). Use the UP/DOWN arrows to select the input for Zone 2. I've only been successful in selecting USB and plugging my iphone in for zone 2. For some reason, I cannot get the SAT (cable box) to play in both zone 1 and zone 2 at the same time. But, I can get SAT in zone 1 and USB in zone 2. Hope that helps. Let me know if you can solve my issue...

make sure that you are selecting the sp2 to be working with zone 2/3. Be careul and check volume to zone 2/3 on front panel before you activate sp2 with zone2/3.
