Had a "Fun" one yesterday.. Noticed power to my Engel Freezer was absent. Checked no power to the power 12 volt power strip (it normally runs on 12v) when I pulled the feed line to the stirp I had 10 volts,, TEN VOLTS? Putting a small load on it (An LED lamp, one LED) the voltage hit zero and fast.
Switched to 120vac for the freezer and went to bed.
Got up this morning.. Re-did the ground lead on the battery, it looked ok but in truth was getting to the point where failere was going to happen, (Not there yet) cleaned and polished while at it (Thia is a 10ga wire hooked direct to the house batteries back when the RV was pre-delivery)
Checked the positive lead, Good solid, 13 vac measured when I piereced the wire load side of the fuse.
This is one solid length of wire, no joints, 10ga "ZIP" cord, from the battery to the power strip.... (Rig Runner power strip)
Started testing at assorted points. All good till I got to the photo.
This was perhaps 2-3 feet from the battery connection, The 'Nick" in the insulation you see in the photo is fresh, I put it there to confirm this was the problem spot.
When I cut the section out I found the wires much tarnished,, When I cut back a few inches on each end and spliced (Solder method) the system now works fine So problem solved.
But I've never seen this in the middle of a span of wire before.. I mean on an end where chemicals and weather and such can get at it yes, but in the MIDDLE!!!.
See photo.
