Trailers about appear with a 4 or 5 wire collapsed adapter or a seven wire annular connector. If your bivouac has an electrical base adapter this does NOT beggarly your bivouac has electric brakes. Electric brakes are a abstracted connection.
The purpose of the base affiliation is to bout the activity of the lights on the tow car to the bivouac lights. This includes the active (night) lights, emergency flashers, about-face signals and anchor lights. A four wire adapter contains a arena wire (connected to the bivouac frame), active ablaze wire (goes to both appropriate and larboard bivouac lights) and about-face signal/brake ablaze wire for appropriate and larboard lights.
If you accept a 5 wire connector, the 5th wire is acclimated for an electrical solenoid on a hydraulic actuator acclimated to stop the anchor if abetment up. This are frequently alleged a "back up solenoid", "reverse breeze solenoid" or "stop breeze solenoid". The fifth wire from the tow car is affiliated to the about-face lights of the tow vehicle. This activates the solenoid if the car is placed in reverse.
Most bivouac ablaze problems axis from a bad arena affiliation amid the tow car and the trailer. Since there is not a arena wire traveling aback to anniversary ablaze (very few bivouac manufacturers add added accomplishments wires), the able arena for anniversary ablaze is abased on the base arena from the car to the bivouac and the arena affiliation at every light.
Indicators that you accept a bad arena affiliation are:
Weak or dim bivouac lights
Opposite ablaze concealment if about-face arresting is on
Running lights go aphotic if about-face arresting is on
All lights dim and agilely blink if about-face arresting is on
Check the simple things aboriginal if all lights act strangely.
Check the base adapter amid tow car and trailer. Apple-pie the apparent connectors with a accomplished beach cardboard or animate wool. Make abiding affairs accept not been cut or scrapped on the pavement.
Check the arena wire from the adapter to the trailer. This wire cannot just be adherent beneath the articulation lip. The wire has to be adjoin apple-pie bald metal, with a spiral or bolt adhering it to the frame. Preferably a abstracted accomplished aperture in the anatomy for this connection.
If alone one ablaze is acting up, analysis the ball aboriginal for able connection, Carefully abolish the ball and apple-pie the connectors on the aback of the ball and central the ablaze housing. Analysis the arena to the frame. This can be a abbreviate wire of just the bolts captivation the ablaze to the bivouac frame.
If you accept a continued alarm wire or similar, you can analysis the arena at anniversary light. Attach an alligator blow at anniversary end of a wire that is continued abundant to go from the tow car to the end of the trailer. Connect one end of the wire to the car frame, authoritative abiding to get a acceptable affiliation to bald metal. Connect the added end to the arena on the light. Compare results. If the ablaze works better, that is the a lot of acceptable atom area the arena affiliation is bad.
If your lights beam rapidly and not a abounding brightness, you may charge a new flasher in the tow vehicle. Consult with a bounded auto locations abundance to alter the absolute flasher with a HD model.
Remember, your bivouac lights acquaint the cartage about you what you are doing. Improperly alive lights are a hazard to you and anybody active about you.
