I am new at this. I have had all kinds of problems with my cable hook up.
does anyone know how to check a cable connection from the back to the front switching box.

The best way to check a cable is with an ohm meter and a alligator clip lead. You can purchase cheap ones at Home Depot, Lowes, Walmart, Radio Shack and many other places. Unplug the cable on both ends. Attach a alligator clip lead from the center conductor to the outside conductor on one end of the cable. Go to the other end and place your ohm meter leads between the center and outer conductor. You should have a short, i.e. zero ohms. Go back to the other end and unclip the allgator clip lead. Go back to the ohm meter end and measure again. You should have an open, i.e. no reading. (the meter doesn't move)

It is possible that you may have an amplifier or splitter between the two ends of the cable... if so the above proceedure may or may not work.

I know of two ways, one is relatively simple, there other a bit more complicated. The relatively simple metod is to remove the cable connection and the front TV connection at the switch box. Using a coupler, connect the 2 coax cables together, then try to get the cable channels on the front TV. If this is successful the problem is in either the switch box or the connections at the switch. If unsuccessful, there is most likely a problem with either the cable or the park connection.

The more compicated method is to run a coax cable from the coach outside cable connection up to the area of the switch box. Remove the cable coax from the switch box. Using a multimeter set to ohms, test the shield from the two coax cables, then the internal wire from the two coax cables. If the wire is OK, you will see a very low reading on the meter for both tests. If there is no reading on either test, the cable is defective. and must be replaced. If the cable is defective, you can get by by running a different coax cable from the park connection to the switch box maybe through the drivers side window. This will allow the systems to operate until you can figure out how to rerun the internal cable. Hope this helps.
