{"text":"I’m pulling a refer trailer and my top marker lights work, my blinkers all work, my flashers work, brake lights work but my bottom maker lights and taillights won’t even flicker. Out of blue it did this. Any wiring wizards in here? Driving a 2006 T600 KW. Probably in my trailer wiring? Yes I’ve been through the fuses and relays and took apart the electrical plugs from tractor to trailer. ","videos":"[]","link":"{}","pics":"[]","canComment":true,"externalShare":false}

{"replyTo":"","text":"Prob a rub through or a previous repair that may have cracked/corroded between the trailer plug and rear.  Pending brand of trailer, we run Utility reefers and our issues all seem to be from where the wires/air lines meet at the bogies and continue to the rear lights.  \n\nJust my thoughts, hope it helps.","replyToPid":0}
