Could you use the antennae boost switch located in the front overhead cabinet as a power switch for a winegard t 4in motion dome?? Is it not just a 12 v power source?
I am installing an in motion satellite that requires a 12 v power source. It comes with a switch but i would like to not have to drill more holes, and since i do not use the power booster for anything thought i might tap in to it. Feasible ??
The switch itself will not work (it's a self contained amp and only coax goes from it to the roof) but there is 12 volts behind it that you could utilize for the new switch... There's probably already a penetration through your roof that serves something that is unused (cell or cb antenna?) Was your coach possibly prepped for satellite?
Yes and i currently have a king satellite dome on the roof. This is the third one i have had(all same models) that has failed and the company says "buy a new one" or send it in to be fixed. I am in canada so cost wise that would be as expensive as a new purchase... all said and done..not very happy
So i am going the winegard route as starlink is:
More expensive
And i have personal feelings about the company
I have all the cable wiring already on the roof installed but the winegard uses a power cable instead of cable powered system and new one has a separate cable
So...ready to go except the power connection
Instead of me running around looking for the 12v power i require i thought the power booster connections might do the trick
You should be able to find the power wire going to the booster and connect into it. That would provide you with a constant 12 volt power source.
There is a pile of wires under the dash that have EXT printed on them and most go to the back of the
coach and I believe a few of them go up behind the TV. They are spare wires that Foretravel put in.
So looking to use the existing 12 volt power wires from the antennae boost switch. I tested touching the white wire to negative on voltage tester and the green wire to positive on tester. I got about 14 volts. BUT i want to ensure these are correct and the white wire is not a false ground. Can you confirm green is positive and white is negative ? Is this the standard colors for wiring with Foretravel?
My new wingard t4 antennae power wire has a red for positive and black for negative
Peter, check for continuity from white wire to metal frame of coach. Jim.
Being more on the dumb side today.. how do you do that? The only other possibility for ground up there would be the metal frame going across the cabinetry but i think it is aluminum
Peter, I assumed you had a digital volt/ohm tester. For basic use a inexpensive one can be had from Harbor Freight etc. Use the ohm setting and one lead to the white wire and other lead to coach frame. Jim.
Well my guess is i will have to dig under the front dash for a ground point and run a wire from it to the meter as my meter cables are not long enough. Then i can check the continuity. I dont see any other ground point by the tv
Maybe i should ask this a different way. Is green positive on wiring and white negative??
Green is negative, ground, or chassis ground, What ever you want to call it.
So white would be power? Funny i directly wite it to my house batteries and everything works as it should?!!!
Peter, do you have any of the coach manuals that go to the coach? There's a good electric wireing diagram in there.
Wow....found some other positive and negative wire s over the driver seat and bingo..it works.. so the power to the antennae booster is not a confident power source... thanks to all for the tips
