Bravo boot light problem

Hi guys, having a problem with the boot light in a bravo.

Light does not come on when the boot is opened. Have carried out various tests.
  • 1 side of light with boot open - 12V
  • same side of light with boot closed - 12V
  • other side of light with boot open - 0v
  • other side of light with boot closed - 0v
  • continuety check of negative side to known good earth - circuit open

Suggests bad earth or faulty switch. Where is the boot switch? Is it a physical switch or a magnetic/level switch inside the bootlid? Which side of the boot light does it switch?

All help will be greatly appreciated.

Re: Bravo boot light problem

Errrm Does not compute

Our survey said
1 side of light with boot open - 12V
same side of light with boot closed - 12V
other side of light with boot open - 0v
other side of light with boot closed - 0v

You seem to have 12v at the bulb holder whether the boot is open or closed yes? This would mean your light would be permanently on and not permanently off. How did you check it with the boot closed? Just curious

The other side of the light should always be 0v as it's connected to earth or should be so that's fine but then you say "continuity check of negative side to known good earth - circuit open"

Open circuit means no earth.

Check the power to the light. Should be 12 v boot open 0v boot closed. If it's 12v regardless then something's up with the switch. If it's 0v regardless then check fuses, switch or wiring

Power off, check light earth conection (the other side) to earth for continuity. Should be near zero ie closed circuit. If not check the earth wire and earth connection

Come back and let us know

Re: Bravo boot light problem

You sure it's switched on the positive side?

Re: Bravo boot light problem

My question exactly.. I thought most lights switch on the negative side of the load.

Re: Bravo boot light problem

Sorry sorry. Confusing myself now. Been working on brake lights all day which work the other way and have the switch on the input

A picture would probably be quicker


If you have 12v on the input to the light but 0v on the output with the hatch closed (and the light isn't working) then that suggests something wrong with the light assembly like poor contacts or the bulb gone. It should be 12v on both sides

The output side of the light should be closed circuit to earth with hatch open (switch closed) so check resistance on that side to earth. Should be zero resistance with hatch open

Re: Bravo boot light problem

If it's of any help, I discovered my boot light wasn't working because the bulb was fitted the wrong way round, I just never bothered to check it until now
