I have a trailer which is parked at a campsite and hooked up to AC. There was a cheap AM/FM OEM radio which I replaced w/ a SONY XR-CA330 AM/FM Cassette, which worked well w/ the existing wiring: I hooked both yellow and red wiring to the hot wire the OEM unit was hooked to. I replaced that SONY w/ a new SONY WX-4500X Changer Control Audio Master (CD/Cassette/AMFM). When I wired it up w/ both yellow and red wires to the trailer hot wire, the unit will stay on for 20-30 secondsand then cut out, come on again, then cut out, and repeats this cycle. I tried every combo of the red/yellow wires but it wouldn't power up correctly.
I have a feeling the issue is with the trailer battery/AC power supply. Can I fix this?
If I can't fix this can I wire the unit up directly to a free standing 12 volt battery? If I can wire it directly how long should I expect the 12 volt battery to supply power w/ infrequent use?
Thanks

This may indicate a low battery condition. If the BAT is not delivering at least 11.0 volts and adequate current, the HU will do just as mentioned. There may be a poor ground connection here as well.
It would be good to test the BAT voltage and general performance of the BAT. If it's old, (3-5 years) It may be on its last legs. Also, your charger may not be doing the job well enough either. Most newer HU can draw close to 10A of current at full power. If the charger cannot keep the battery up to snuff, this will cause the same issues.

Thanks, Swez. Come to think of it the batteries are probably > 10 years old. I get weekend use out of the trailer 5-6 months a year and as long as the lights and H2O pump work, I'm happy.
I'll start w/ the battery check.

If the batteries are worn out, consider replacing them with Deep Cycle types. These DC batteries last a lot longer and can take many complete discharges/recharges and keep performing well.
Typical lead/acid, car start batteries work fine if they are kept in a well charged state at all times. However, after a number of deep discharge cycles, the performace deteriorates quickly and the batteries fail well short of a DC type BAT.
Good luck,

NEW INFORMATION:
The trailer is hooked up to a 120 VAC line, which goes directly to a power converter which is designed for 45 amp max continuous load. There is NO BAT, but there is a hook-up for a BAT. The power convertor has an automatic relay to switch over to BAT when 120 VAC is disconnected.
QUESTIONS:
1. Since the HU is cutting off, does that mean the power convertor is bad? All other components seem to operate well: coffee pot, minifridge, shop vac. If all these other appliance operate why would the HU be cutting off?
2. Would it do any good to install a BAT?
Thanks.
