Question:

My lights wont come on my Demco Kar Kaddy SS. I have good voltage up to the tongue where it connects to the 4 pin in the trailer. Where do I check next

Expert Reply:

Since you know you have good voltage and ground connections at your 4-way on the Demco Kar Kaddy SS Tow Dolly # DM9713045 you will want to next use a Test Light # PTW2993 to check power going into the tail lights. This will help you to determine if the issue is with the Light # DM45MV or the wiring. If you have power and ground going into the tail light then you know the light is bad. Otherwise you will need to trace the wiring for any shorts or damage to the harness.
