Default Who understands the workings of the steering column?

If so, I have some questions concerning the interlock. I have circled it in this picture that I stole from someone selling a steering column:



The part I have circled is the interlock device I guess. I am not quite sure how it works and was wondering if anyone knew.

Thanks,
Jonny

Just a simple solenoid that is engaged anytime the car is in gear. It's what keeps the key from being turned to the off position until the shifter is moved to park.

OK, wonderful. So on that basis having this thing disconnected is not going to effect whether or not the car would start? I replaced the steering column but ran into an issue with this solenoid and didn't end up putting it back in due to a broken part (so technically it if I put it in it wouldn't have worked anyway.) Trying to get the car started I get a single click, which I'm 99.9% sure is the starter, but this is on a 400 so don't want to replace the starter until I am 100% sure it is the culprit.

That was a mouthful!

Thoughts?

Yup - I own 2 x SC300's and 1 x SC400... and the 400 has to be the one with the starter issues

That is correct, the absence of that solenoid should not affect starting.

If you want to make sure it's not the ignition switch causing an issue, you could power the starter motor separately of the switch. Temporarily connecting the heavy gauge white wire(12 volt constant) and the heavy gauge black/white wire(starter input) should engage the starter. Both wires can be found at the back of the switch. I would recommended testing the wires with a multimeter first.

I have jumped the starter relay but still got the same clicking. Wouldn't this basically be the same test, in effect, bypassing everything and putting power straight to the starter?

Yeah, both tests should have the same outcome. Sounds like the starter is getting power as it should.
