Hi all,
I've found the reversing lights not working today, the is no power to the lights, I have traced the two green wires to the switch on the side of the auto gear selector.

I have power to the switch and power out of the switch when in reverse so I'm guessing everything is OK there.
I've run a temp wire from the green / brown wire (power out) terminal direct to the light and it works so I'm guessing the wire is damaged somewhere from the centre consul to the boot.

Anyone have any ideas on a likely place to start without ripping the interior out?

On another issue the heater fan will only work on high not low or mid, would this suggest the switch is knackered?

thanks

in the Series 3, there is a roller switch on the right front side of the shifter that needs to be correctly adjusted so the reverse lights are activated when the shifter is placed in reverse gear.
if the Series 2 is different and there is no roller switch, then the reverse lights switch must be at the side of the transmission.

My Series 2 has the same roller arrangement to activate reverse lights.

Elinor Hello! haven't read from you for a long while!

good to know Series 2 have the same reverse switch. That is where I would check first. After all, why would there be a broken wire? wires just don't break by themselves.

 

Do I recall ? I think so. My 83 had the reverse light switch on the transmission. It departed on getting "lumped" .

I had two options to replace it.

1. The conversion kit from John's cincluded a similar witch and the means to attach it to the shifter tower.

2. I sourced an XJS shift tower from Andrew's Jaguar Specialties. Same switch, but a better means of attachment Plus a shift detent pattern better suited to the GM transmission

Alas, something went bonkers. Reverse lights always on. Not a jag pattern, usually go dark...

Bodge. Removed bulbs. One day, I may open the console and fix??? durn I sold the ortiginal tower, new switch and all!!!!

 

Heater fan speeds are normally varied using resistors, with max speed not having a resistor in the circuit. It is a common fault on my MG TF heater, apparently.

 

Thanks Frazer, so where would I find the heater resistor ? and how would I test it?

I'm going to spend some time tomorrow having a poke around with my multi meter and I will take a photo of the reversing switch by the selector that I was talking about that I have power too and works correctly. If there's another one on the transmission i will find it!



thanks for all your help

 

Hi all
just a quick update on the reversing light saga

I took a look underneath and there are no wires to be seen anywhere in the transmission tunnel,
this picture shows the switch in the cabin, the removed green wire is the one that I ran a direct cable to the lights and when reversed is engaged worked so I'm assuming the switch is OK.


Am I correct in thinking that this wire runs directly to the reversing lights and not via any other inhibitor switch or fuses?

thanks and Happy New Year!

I believe that switch requires rotating it with shifter in reverse, ignition switch in ACC or RUN until the reverse lights come on. Loosen the nut in the threaded neck and rotate it clockwise or counter-clockwise

However, I don't know if that switch also works as the Neutral Safety Switch. I would confirm before rotating it so you don't lose the NSS adjustment.

 

Yes, because, as Jose mentions, you could easily lose neutral start safety operation.

My car for example, very happily starts in Reverse! as I discovered quite by accident very early in my ownership.
Fortunately, there was no harm done, she merely rolled herself back through the open door, off the jack stands under the front bumper mounts, which jack stands then went flying across the shop with much clanking as she chirped her tires with fiendish delight.

Didn't even leave a mark on the bumper but I have been Very careful since that time to start only in PARK.

haha!
that reminds me of my first ever oil and filter change in the MG-B.

I drained the oil neatly but didn't put the drain plug back.

refilled the engine with 3 or 4 quarts until I noticed all the new oil had drained under the car on the floor.

​​​​​​My father said "well at least you didn't drive away with no oil in the engine, could have been a lot worse, better clean that mess before your mother sees it".

 

the fan speeds resistor is located on the left side of the evaporator box, high above, mounted to the box with tiny screws.
Remove the screws and pull it complete with wires attached to it.

Hi all
Just to conclude the reversing light issue.
I located the wiring loom in the boot behind the off side panel which had power to the bullet connector that fed the reversing lights so I knew the issued was located at the back of the car. On closer inspection I noticed the wire around the hinge was broken, it looks like someone in the past when tightening the nut had move the clamp, which in turn must have take out all the slack and resulted eventually in the broken wire.



Now on to the fan issue!

thanks
