Re:Info best way to track down shorts.


First put yourself back to when you last remember wearing your shorts. Okay, but seriously, you need to isolate the short. In the case of pass-thru power taps, you either need to use a stop-power face plate or a tie-wrap or other non-conductive material to stop the mechanism that passes power when the tap-plate is removed.
I have found 7 out of 10 shorts are connector related. Either the cable center conductor is bent & cause the seizure mechanism in the connector to short out or the pin is too long on the connector & shorts in the equipment. In UG &MDU situations if the splicer was sloppy when prepping the cable the aluminum scrap can fall into the cored out cable end & create a short that is the dickens to find.

The previous examples are mostly from new build/re-build/upgrade situations. If this is existing plant that has a catastrophic failure short, again try to isolate. Now you're job is harder as it could be burnt out equipment, or damage to the coax from fallen branches, a pole hit, lightning strike, or the dreaded underground sprinkler system installation that nicked the jacket of the cable & over time the water seeped into the insulation to create a short. Or it could be the tech from the HBO comercial sitting on a pole using a screwdriver to wreak havoc.

You don't always get what you expect, but you know what you got when you inspect. Happiness comes from within, some poor souls are just without.
