Hi! Hoping to get some help here with my turn signal issues. We have a new to us 1984
Burro wide body with nearly all original parts.
Here are the issues: when the tow vehicle
lights are on, only the large bulb in the lower large rear fixture
lights up. Left does nothing.
When the left turn signal is on in the tow vehicle, the the larger of the two bulbs in the rear large fixture blinks, but nothing else (amber left, small red upper and small red lower) blinks.
When the right turn signal is on in the tow vehicle, the smaller of the 2 bulbs in the big right rear fixture blinks, plus the amber, and the upper and lower red blink. If the tow vehicle
lights are on the big bulb lights up but stays constant; with the right signal on the left amber, small upper red, side lower red, and small rear red
also blink, (but not the big lower left bulb in thar fixture). This is the result regardless of whether the tow car beams are on or off.
When the hazards are on,
everything on the left (the amber, the small red lights
and the lower big
light bulb) blink. This happens with the tow car beams both on and off. On the right side, when the hazards are on, all the small lights (amber, upper and lower red, and small bulb in rear light) blink, but not the big bulb. The big bulb only lights up if the tow vehicle beams are on and stays constant with the hazards engaged.
All bulbs are functional and operational—at least when they get a signal….
From this testing, I am deducing that the large bulb in the rear fixture is supposed to be on when the tow beams are on, but should not blink. I am also deducing that, normally, the small series of bulbs (the amber, the big and small red fixtures, and the small bulb in the big fixture) are supposed to blink when the turn signals are on. The big bulb in the rear fixture should stay constant.
So I have some sort of issue on the left side.
I am fairly certain the issue is the trailer and not the tow vehicle, although not 100 percent. It has an after market hitch. I took it back to the hitch installer to have the hitch wiring and it appears to be working correctly. Note: the wide body
Burro requires a 7-pin hitch.
My Internet research indicates that a bad ground might cause trailer
lighting problems. I confirmed the ground in the tow vehicle is good. I consulted the really helpful wiring diagram for a
Burro on the “documents” page, but I cannot for the life of me find the ground to the chassis on the trailer itself. That was going to be the next thing I was going to to try.
Could anyone advise where to look for the trailer chassis ground? I will note that there is an extra white wire coming through to the right large rear taillight fixture that connects directly to a screw—is it possible that the ground????)
I am also open to other troubleshooting ideas. Thank you in advance for your thoughts.
