And first thing at 5:45 am today.
Trailer for service and I notice it has a dim top right marker at rear of trailer. Load my tools on the Genie
and up I go. Now so people understand this marker on this certain brand of trailer also flashes with signal.
I had already seen a repair order from another shop charging roughly $130 labor plus parts three weeks
prior. Remove the rivets for cover plate and a brand new Super Nova was installed, problem was it wasn't
the problem.
The harness in this trailer was made by Truck Light on bid for Van Guard Trailers. This particular marker
is a Dual Intensity Super Nova, built with resistor inside harness so it interrupts constant marker power
with a right hand signal power.
Well it was pretty obvious who ever worked on it thought it was a bad light with poor grounding. So they
just cut the old one off and spliced in a new marker-that didn't fix it so just fack it and run it out the door.
Below is the culprit the resistor built inline and the whole thing hardwired as a unit with light.
I cut it apart to show the orange/brown corrosion collected on white/ground and shrink tube cover.
Obvious they didn't check for ground first but they did check for power by poking a test probe into
marker wire. The thing is this light is not a DOT mandatory signal light so the fix is remove the whole
piece, forget the signal wire and turn it back to a 2 wire marker. This pos is roughly $25 bucks a piece.
But this is one of those where who worked on it had no clue.
