Hey Folks,
I have an '89 240DL, the brake lights are all out. Bulb failure light comes on when brake pedal is presses. I've scoured google groups but still have some questions.
Fuse # 7 is good fuse port carries current brake light switch has continuity switch wires get current as needed
From what I've read I know that I need to check the relay, #54, etc. and check the light sockets themselves. But I have some prodedural questions.
- How exactly do you get that damn cap/plug off of the relay?? It has a lever type thing in the center of the wires, but no amount of pulling, prying, etc. will loosen it. Do I need to pry it off with a screwdriver?
- To check the relay poles, will a standard light-up circuit tester pen do the trick? (not if the cap is off, I know) Do I need to use a multi tester? How does one test the ports on the relay?
- Would someone please be so kind as to breakdown the process of testing the taillight/brakelight sockets for current, etc.? Where exactly are you supposed to probe on the light assembly?
I'm pretty new to using the multitester and circuit tester so any guidance advice is appreciated.
Thanks, and this is one hell of a research archive.
