Power to tv

Can someone tell me if while parked, and you are listening to the dash radio with the ignition key on, does it prevent the tv from working off 12 volt dc power? On my motorhome, a 2008 Tioga 31M, the VCR is connected to what appears to be a 110 receptacle labeled as a PowerTek RL 1003 which has a relay which turns on when the ignition switch is on, disconnects the tv in order to comply with a vehicle code which requires that a working televison must not be in direct view of the driver. My tv is on a pedestal above the front cab area, next to the overhead bed and not visible to the driver.

  • The issue is that when the key is turned to the on position, or the engine is running, power to the outlet where the dvd player is disconnected. This is because the dvd is connected to an outlet called a PowerTek Lock Out Relay which disconnects power to the outlet when the engine is running. The tv is connected to a separate 12 volt outlet, and is not affected, however, loses any signal. This is designed to comply with vehicle codes which state that a working television must not be in direct view of the driver. I don't know why Fleetwood did this, since the tv is above and behind the cab over the driver's head (Class C) and cannot be seen by the driver. I read up on a cure that will bypass this bypass and allow my passengers to watch tv from the dvd player while I am driving. Problem solved.

    First, if you are listening to the radio, you could use the ACC setting (I can not, however tell if that messed up the TV) or perhaps switch the radio to aux battery power.

    IF the TV runs of 12 volts odds are it will NOT be affected

    if it runs off 120, it will, at least if the switch is in ON (not acc) position.

    But why would you want both TV and Radio at the same time? Story follows:

    years ago I was watching the World Series at a campground in their T room, Well their TV had a problem, bad transistor in the audio circuit, sounded like..... Well i won't use that word here.

    I told the assembled I'd fix it and went to my camper, came back with the BOOM Box, tuned to WJR and Ernie Harwell calling the play by play, We turned the TV's audio to OFF.. For years after, that is how everyone in the room watched a Tiger's game.. Alas, Ernie is gone now, and his replacement is .. Well.. not him, he was the last of the great play by play men.


    Well, we still have Vin Scully after all these years.

  • The tv is connected to a 12v outlet, but the vcr is connected to the 110v outlet which has the lockout. Even if I switch the vcr to another nearby 110v outlet, I won't be able to use it when on batteries because my motorhome does not have an inverter, only a converter. If I turn on the ignition key, both vcr and the tv shut off. I suspect that both outlets are wired together. I could bypass the lockout, like Johno02 said, but since I only have an inverter, I can only run the tv off my batteries, but not the vcr. My intent was to only run those two items off the house batteries when boondocking. Instead of buying an expensive inverter, I think I will just buy a cheap vcr that runs on batteries and convert the lockout outlet to a DC. How does that sound?
  • After rereading your original post, is your TV working from a 12V outlet?? Usually the lockout is only on a 110v circuit. for a 12V outlet, the only way the ignition would effect it is if it is wired into the accessory circuit.
  • Its very easy to bypass. Like said, just use another unswitched outlet. Or, disable the switch. As long as you do not have the tv on when driving, no one is ever going to check anyway.

    don't know the answer but a buddy with a different make/model of MH found that he could by-pass the lock-out function by unplugging from one side of the standard outlet and plugging into the other side of the outlet. don't know if that was intentional or just sloppy workmanship but it's worth a try. as long as the driver can't see the TV you won't be in violation of the law.
