I'm Awesome
Just bought an 88 Shasta 210 trailer.
Its got a 7blade connector, elec brakes etc.
So, I have a 92 K1500 Suburban, with towing package.
I wired in a brake controller and a new 7blade connection. According to the instructions that came with both, its all correct.
When I hooked it to the trailer I had signals, flashers & brake lights. No tail lights or markers.
When i turned on the tail lights on my truck it would blow the 20A fuse.
After looking at the trailer connection, I found that the taillight and left signal wires were in the wrong space, as they correspond to my truck connector.
SO, I switched them so that they were in the correct position to match up to the truck...
Not blowing fuses anymore, but now I only have a right tail light, signals, 4ways, brakes.... NO left tail or markers
in addition to that I have found that the hotwire (part of towpackage) blows its 30A inline fuse AS SOON as I hook the trailer to the truck.
In testing voltage, I found that my hotwire reads +12 volts at the connector... the trailer's hotwire reads -12 volts...
Does that mean reverse polarity on the trailer? If that is the case, would that explain the blowing fuse everytime they connect?
The wiring that I can *see* looks okay... does this indicate that the trailer's hotiwre has grounded someplace?
Thanks!
