Hi All,
I have just purchased a 1978
Trillium 4500 (bathroom model -
VIN 1100892) and am having some issues getting the turn and brake
lights to come on. The trailer has the standard 7 pin round plug and my car (Ford Escape) has the 4 pin flat connected to the rear
lights, with a Reese 4 way to 7 way adapter in between. I've connected the two ends and grounded it to the frame of the trailer, but when activating the turn
lights on the car the trailer lights do not come on.
Steps I have taken so far:
1) Verified that the connector on the car is working (hooked up another trailer directly from 4 pin to 4 pin and the lights work)
2) Confirmed that the connector on the trailer is working (hooked up a truck with a bulit-in 7 pin connector to the 7 pin plug on the trailer and everything works)
This tells me that everything at either end is working, and the issue is either with the adapter or the grounding. I tried a brand new 4 pin to 7 pin adapter and still no luck. I checked all the contacts and they seem fine; used a multimeter to check every pin on both the old and new adapter and everything is working.
Any help would be greatly appreciated. Looking forward to many years of use with the new (to me) toy, but until I can get the lights to work it is sitting on the seller's property :-(
