on my 65 24' tradewind, only 2 of the 10 clearance lights are functioning.
i'd like to repair the originals on the trailer since they are in decent condition however i don't want to go nuts and put hours of labor into each one.
as i understand it, the positive(hot)feed is on the bottom of the bulb(blue arrow in photo) and the ground on the bulb is the brass cylindrical portion(red arrow)
is this correct??
i ask because i am completely stumped???
i removed the lenses and on the bases, completely cleaned all brass contacts as well as the round ground collar that touch the perimeter of the brass contact(ground) on the bulbs. i also cleaned the bulb contact points.
i used my 12v
tester and using the trailer skin
as the ground, i tested the (hot) wire attached to the brass contact on the clearance light bases and all are getting juice - i also tested the brass contact points where the tip of the bulb touches and all are getting juice.
**when i try using the round ground portion of the clearance light base while testing i get nothing. even on the 2 lights that are functioning, when i use my tester i get no ground from the round ground contacts surrounding the bulb??
so my question would be am i incorrect assuming the round portion of the clearance light base that surrounds the bulb is NOT the ground??
...and does anyone have any idea what the heck is up with these lights?? again i am getting hot juice to all lights so it is some sort of disconnect within the light base itself - wondering if i can maybe solder and reground the bulb surounds possibly?
