Default Brake light relay...


I bought my 1999 XK8 several weeks ago and have been having rear light issues from day-1.

Here's my question...does the brake light relay take a different relay than the other relays in the board?

The one that is in the brake light slot now is LJA6703AA.

Here's what prompts me to ask;

I removed several adjacent relays and took my volt meter to them and easily found the hot plug, the ground plug, etc.

But all 4 posts on the brake light relay had voltage running to it, and the voltage left one of the posts when the brake pedal was depressed. The exact opposite of what I would expect.


My assumptions would be;

-This relay slot uses a different style of relay than the other slots


-I have a short in the wiring somewhere before the relay slot.

If this slot demands a different relay, then I would be one happy boy, so any help here would be greatly appreciated.

The electrical schematic shows the stop light relay to be the same as the related (tail, backup) relays.

There is a history of ground problems in the tail light assembly.
