Congrats.Next time get a bigger bike.
Or a stronger wife.
Nice find.
Slim hopes of that around here. This is what I see walking down my streets.

You can fit a fair bit of electronics in 100G bins.
 
Well we now know why it was at the street. The amp (Onkyo A RV401) doesn't work right. The good news is the CD player (Onkyo DX 700) works and tuner (Onkyo t 403) probably works too, but I haven't tested yet.

The amp powers up, and the input selector, volume and tone controls work on both channels. The bad news is there is no volume to speak of. At half volume it sounds like a small transistor radio on low volume. Too bad since the specs on this amp look ok. Would have made a nice 100 wpc garage party amp!

Any suggestions on trouble shooting? I am a total noob in this area, but certainly willing to give it a try if anyone has any recommendations.

Cheers
 
Looked like Sony rack system stuff. Didn't really give it much of a look since the bike was loaded. Looks like I need to invest in a bike trailer.
 
Yep, time to check if there any type of speaker relay where contacts could be corroded, or it's not pulling in fully. Could be also bad DC output so it's in protect mode, needs additional troubleshooting.

Does it have any pre-out / main in jacks? Then you can split the sections and see which one isn't working right.
 
I picked up a Sony AVR receiver on the curb that had practically no output on one channel, even after a DeOxit treatment to the controls. So I took off the cover, hooked it up to some test speakers, and used a chopstick (non-conductive) to tap various components inside, and located a ribbon cable that was making poor contact at the board. Wiggled that around, applied some Tweak, and it's now in the AV system.

It may be a relay problem. Does it make a click a few seconds after you turn it on?

Yeah, the relay clicks and very low volume music comes from both speakers.

No pre-out / mains for that check. Some of the other items are outside of my current skill set.

This I will try!

Thanks all. I'll poke at it some more to see what I can learn.

Ribbon cables - more than a few times, reseating these (including in my own Sony receivers) has been the cure to the problem. Excellent suggestion.

Well, well well! Kirk57 and reydelaplya were dead on!!

Got in there and started poking around with a paint stirrer (not too many chopsticks in the house). Poked on one of the ribbon cables and the unit shutdown. I thought I had killed it as it didn't want to come back on. Unplugged for 15 minutes and went back to try again. Turned it back on and damn near jumped thru the ceiling when the relay clicked at half volume! Glad I was using the tester speakers.

Let it play for a few hours on the test speakers just to make sure nothing abnormal was going to happen. I hooked the amp to my small Infinity RS 2000s and it sounds pretty good. The tuner doesn't impress me, but not really an issue.

I was out in the truck today and went back to see if the speakers were still there. The main speakers were gone, but the Sony sub was there was I brought it home. Hooked it up on the "B" terminals with the test speakers just to see if I worked and it does. Not sure what to do with it though.

Hook the sub up for the garage system or add it into your main system, one can never have too many subs.

Well done. Not many people have a spouse who would A) let them pick up garbage at the road side B) allow A) while they were present and C) assist is dragging A) home using pedal power. Heck most couples can't even cooperate long enough to ride a tandem bike.
 
That's a nice find, but I pity your bike's rear wheel.

That is about the third or forth wheel we've had on there, and I just put two new spokes on the backup wheel. You are right about the rear wheel taking a beating. There is a lot of torque and weight on that wheel. Glad I had that tire aired up good.

We've been on the tandem for a long time, and for better or worse we both tend to get a little junk drunk at the sight of a pile of old stuff so I have a partner in crime. She even asked me if we didn't want to go back for the speakers, but I told her no as the were not an upgrade.

You should get a rear wheel laced and trued by Mark Pace. He has a shop here in Independence, in an old firehouse. He built me a set of wheels for my Peugeot road bike, using hubs I supplied and the widest rims available. $350, and the first time out with them I got ONE ping. They have never needed truing, and that is after maybe 20-25 years of use.
 
Spoke count matters on tandem rears. Also wider rear dropout spacing helps, as wheel dish is not your friend here...

Yep. ..I lucked up and fixed a Sony 555ES this way. The relay kept clicking due to a loose ribbon cable leading to the power supply board
