Am I inhibited ?

Post by Korporal brunhausen » Thu Jul 04, 2019 11:43 pm

My SE6A is about 6 months away from it's 40 birthday and when I was getting it ready for it's
last MOT trying to sort the lighting down the back, including the reversing ,stop and the indicators etc. When this was done, I found I couldn't then get the starter to operate.
I thought straight away that it might be to do with the inhibitor as I recall there being some connection between this and the reversing lights.
Have I gone and messed the inhibitor up now?

The starter should only work with the lever (and hence gearbox) in Park or Neutral.

If the reverse light comes on in park or neutral you will have put the connections on incorrectly

Check the condition of the wiring from the inhibitor to the starter relay then to the starter motor. Just renewed mine as the wires had gone crispy under the insulation. The plug onto the inhibitor is unavailable but you can get the wiring loom from here; https://www.autosparks.co.uk/finder.
Fitted this my GTC hey presto all worked for the first time in years.

When I bought my Gtc the starter inhibit switch was bypassed. The switch tested ok for continuity between the centre pin and the first pin (reversing lights) the third pin gear lever position inhibit should have continuity with the body of the switch when the plunger is depressed. On the Gtc the inhibit relay is in the engine bay by the wiper motor . This had also failed as it was fitted upside down allowing water ingress.
Not sure if any of this helps on the 6a
Bought a second hand switch and a relay from Nigel at QRG

I’d check the relay first as that will quickly tell you if it’s the inhibit switch - as Pete says, in park or neutral the inhibit switch should provide an earth path to the starter relay, so check you have 12v in (probably pin 86) and an earth path at the coil (pin 85), then 12v in (pin 30) and out to the starter motor (pin 87). Pin numbers can be swapped but as long as the coil is 86/85 and it’s making the contacts between 30/87 when energised, it’s fine.

I read that as meaning it was working until you did some work on it . hence my suggestion

Many thanx guys for the suggestions, I'm really glad to have joined the forum.
I notice there's no clicking coming from the solenoid and the 3 small wires have voltage ( lgnition on etc) white - 6V ,Brown - 12V, Red -0.
I'm hampered a bit in that whilst I know that a relay is essentially a switch, I don't know what they look like, or the location etc. Only thing I can think of are blue plastic cylindrical things dotted around.
Can anyone put me straight pl?

I’e done some low level photography and the prints are back from Bonusprint ....
Is the reverse inhibitor in shot so I can check it. By messing about with wires I’ve had the starter turning and the ignition switch seems to be ok so I’m going to concentrate on the inhibitor and it’s relay, But first I need to find it, can anyone help here please?

The Inhibitor switch is ABOVE the cable in the pic. and is JUST visible above the kickdown system.

The cable should be connected to the lever to the right for the kick down to work.

Just to enlarge on that, the inhibitor / reverse switch is a tubular device with a plug that goes onto it vertically. It has four connections going to it from a sub loom that side of the chassis. You can reach up and pull the plug off for testing. Getting it back on is a bit more awkward but as it is keyed, you can't get it wrong. I have lots of photos somewhere, but can't put my hands on them for some reason.

I found it was best to remove the plug on the inhibit switch from under the car it's a bit of a fiddle. Then the inhibit switch can be removed using a long reach six sided socket on a very long extension. From pax side of engine bay it can be seen rear of the bell housing. I have also replaced the wires from the sub loom to the starter solenoid which were in very poor condition causing an intermittent loss of the ignition light ( Gtc)...... I'm ever be short of something to occupy my time in retirement while I've got a scimitar...all part of the fun!

Thanks guys for the additional info, I can now get going to try to raise the car a little to implement the advice given.
Pete, I had an SE5 back in the late 1970s and it was very much like you have described - always something needing doing!

The latest pic is great, thanks AJL, but I've drawn a complete blank over the weekend and I only got the rubber plug off. The rest is solid.

To play safe I think I will tow the car to a friendly garage 1/4 mile down the road at ,say, 10/15 mph. I know the probsassociated with towing an auto, but with a short trip would I get away with it ?

Thanks guys for the info provided.

John B.
