Reverse Lights

[ToF]

Hey guys,

My reverse lights aren't working on my manual R32 GTS-t.

So far I've tried looking at the basic stuff first. I tested both reverse lamps and they aren't blown. I also decided to check the voltage across the reverse light plugs (at the rear bar not gearbox yet) and it was reporting 0.06V in reverse and 0.04V in neutral on both sides...

And just before I went to check every fuse under the dash and 2 were blown but I'm not sure if they are related. For starters, wtf does the "Shift lock" fuse do? (Can't be central locking because it's currently working). The "Transmission control" fuse was also blown but isn't this used for Autos only?. (BTW: My car used to be auto)

I don't have new fuses on me at the moment so I'll have to replace them tomorrow but can anyone let me know if the reverse lights are related to those 2 fuses and what these fuses do.

Thanks

BTW: I was going by the fuse labels used here: http://www.skylinegts.co.uk/R32-Fuses.htm

So no one knows what the "Shift lock" fuse does or if the "Transmission control" fuse is used on manual?

Or anyone know what else I could check?

I've seen auto cars with a shift lock, so i'd guess that it is for locking an electric auto gearbox into gear.

As for the reverse prob, I have it too on my R33, and i've been told that there is a reverse-switch on the gearbox. I've located what I beleive it to be, and it has a wiring harness on it. Makes sense though... how else do the lights know when to come on? =-]

Sounds like your car used to be an Auto.

There should be the best part of 12V at one side of the reverse lamp when reverse is engaged (with Ign = ON). Check both sides for ohms to earth (1 side should be 0 (or close to it) - that will be the earth / -ve side).

I'd put money on a broken reverse switch in the gearbox, or a broken wire attached to the switch.

I haven't had time to check the wiring next to the gearbox sensor yet but I will this weekend. If the gearbox switch is broken are they expensive to replace?

And I don't know what you mean by there should be 12V on only 1 side of the reverse lamps, shouldn't each lamp be getting 12V each?

Also I'm guessing the the reverse lights has no relation to the "transmission control" and "shift lock" fuses since they had to do with AUTO?

OK, I just replaced both fuses and the reverse beeper started beeping for 5 seconds then instead of beeping it now does a continual whine. At that time my reverse lights worked but after a short drive I noticed the beep and lights didn't come on when it came time for me to reverse. I checked the "Transmission Control" fuse and it's blown again.

Stupid of me but for the moment I've put in a 15amp fuse to replace the 10amp.

So does anyone have any ideas why the fuse would blow after a short drive?

I'm thinking I might have the wrong rated bulbs in, so does anyone know the correct rating for R32 GTS-r reverse bulbs.

ahhh.. so whoever did the conversion actually wired up the reverse-switch on the gearbox eh? On an auto, I think the switch is in the gear-selector.

So.. it's been hooked up, but blows fuses... and the beeper whines. I'd take a guess and suggest that there is a short somewhere that causes the beeper to stay on, and the fuse to blow. I wonder if the beeper runs off a relay?

I just did an auto to manual conversion.

The shift lock is only for the auto.

It locks the car in park until the ignition is on and your foot is on the brake pedal.

Transmission control is auto only.

I guess when they did the conversion they left some of the unused wires to short out and blow your fuses.

If the reverse lights worked since the conversion I put my money on it being a worn out reverse light switch in the g/box. It's very common. They cost about $25 from Nissan.

If you've never had them working then they may not have been hooked up properly when the conversion was done.

Check the neutral position switch as well.

I've been told if it's not working the car thinks it's in neutral and retards the timing.

Both switches are on the drivers side of the box and look the same.

The rear one is the neutral switch and the front one is reverse.

I posted a thread on how to wire these.

Of the wires that went to the auto box the green wire and the thinner of the two black wires are for the reverse switch and the white and the same black wire are for the neutral switch.

They all plug into the cluster of connectors mounted on the side of the fusebox under the bonnet.

Just make sure the right wires are hooked up to the right switch.

The beeper is part of a module called shiftlock controller

On the auto I converted this module was mounted on a bolt that is used to mount the clutch pedal box in a manual so I disconnected it and threw it in the bin. No problems.

Get rid of it.

While you're under the dash check that the clutch switch is wired up. If it's not, there is a plug for it taped to the auto loom just above the clutch pedal.

The clutch switch helps to stop the car from stalling when you clutch on the overrun or during gear changes.

This is often overlooked during conversions.

Hope this helps.

No way! I've been hunting for a USED one, thinking Nissan wouldn't have them new anymore... but like everything, it's prolly a Bosch switch eh?

Cheers!
