Reverse Switch On 280 G.box Faulty?

i think i have the same g.box. lurch said it came from a non turbo 280

the text says its the one with bullet connectors, but i can;t make it in the photo. is it the ones closest to the clutch hole?

i've tested them all and they're all "open" when reverse is selected

 

 

[C.A.R.]

 

Remove the switch from the g/box.
Plug the wires in.
Turn on the ignition system.
Activate the ball in on the end of the switch. 

If the reverse lights stay off, the switch works. If they stay on, it's faulty.

You could also test it with a multi meter out of the car.

Make sure you install the switch into the correct hole, which will probably be the bottom one (5th/Rev rail).

If you can't handle all this, I suggest you stake up stamp collecting.

Check your reverse lamp Earths. As well.

The passage of years can play havoc with electricals that lie dormant.

all good, thanks for the stamp collecting advice - that sounds too mechanically intense for me

it was oil inside the bullet connectors under the car, so resoldered a new set and as good as gold

don't know what the other sensors are for - i think someone said its for neutral and 5 th gear?
