Brake lights, Horn issues
I hope some of you can help me with this issue. Purchased a 96 Disco SD 60 days ago and after much work am almost finished putting a it back on the road. Now, the only thing stopping it from being road-worthy are the brake lights and horn. Both of which were the only things working when I started the project. (Not really, but close.)
All other electrical is functioning normally, including lights, markers, and third brake light.
Troubleshooting and quirks.
Brakes and horn, all fuses, bulbs are good. Brakes, replaced stop switch at pedal.
When the key is in the on position only, the third brake light works when plunger is depressed using the old stop switch. It stays on regardless of plunger position with the new stop switch when the key is in the on position. No power is present at the fuse box leads for the horn or brake lights when the key is off. (This is my first Rover, But every other vehicle I have owned has had continuous power to both leads. regardless of key position. Shouldn't this be the case with the Disco?) With key on, all 4 pins at the stop switch have current. Activating the plunger breaks the current to the outer pins. (Is this the norm?)
Items repaired or replaced during the time these components stopped working: ignition switch, fuel delivery system from pump to injectors, brake master cylinder, steering gear box, rewire rear windows (center console partial dismantle), engine dismantled to long-block, cleaned and inspected.
When troubleshooting the fuel system I went through the relays under the passenger kick-panel Pulling and switching out with one another to check each for continuity. Could one be wrong? In addition the bottom satelite fuse box was out of place. When rewiring the rear windows I spliced into the rear window lead at the fusebox with a new wire and bypassed the old wire. I did not snip the old wire, Instead I T'd into it, then snapped the satelite fuse box back in place.
The issue of no current to the brake light switch lead unless the key is in the "on" position seems wrong. Could I have pulled a lead from the fuse box when I repositioned the lower satelite fuse box? There are some open leads behind the fuse box. But, it is the SD version. I assume these are from leads regarding options the base Disco does not have. Maybe I am wrong. Does anyone have any ideas? does anyone have a wiring schematic?
