Aye - I knew Cap'n Dave would solve this mystery!
He's been sailing the seas of Lucas for many a year.

But as far as dumping ye' old clutch with the car in gear and foot on the
brake . . . Aye - normally stalling it out would be the trick!

But the car hasn't been driven in o'er a year.
Seeing as how I haven't tested the brakes or clutch . . . I wasn't keen on
taking that route.

Besides, at this particular time, the car happened to be up on 4 stands
(ramps) which were actually propped up further off the floor by a few 2x4's.

All that Rigging had my TR6 up on the Poop deck.

I did once make a car walk the plank.  Shiver me Timbers!.  
I don't wanna try anything that might cause that to happen again.

What happened was that I was testing wires and the ignition switch was
dangling down, hanging by its wire.
I went to turn the key off (it was in the accessory position) and turned it
the wrong way.  ARR!

The car was in gear me hearties.. .the hand brake was on. . .but that
starter motor had plenty of UMPH.
It spun one of the back wheels and shot the ramp Smartly Aft.  GANGWAY!
I tell 'ya me 'lil TR looked like a beached Amphicar!

The wee coil wires on my TR6 are the ring terminals type.
I'd have to pull out a nut driver to get them off.
Is it BAD to pull off the high tension lead from the coil to the
distributor?  
Should I go to the trouble of getting out the nut driver next time?  (or put
spade terminals on it I guess)

Much Obliged Cap'n . . . err . . .   

How do Pirates say thanks?

Maybe they don't say thanks.

If
you short the two wires going to the ignition warning light bulb . . .
should you still be able to turn off the engine?

Nope.  The ignition light indicates a voltage difference between the white
wire and the regulator power supplin in the alternator.  If the bulb is
bypassed the alternator is generating voltage which is being fed directly
to the white wire which powers the coil (and everything else that is
supposed to shut off with the key).  

Next time this happens you can pull the white wire from the coil rather
than the high tension lead.

Another thing you could do is put the transmission in fourth gear and dump
the clutch with the other foot firmly on the brake.  Once the alternator
has stopped turning it will no longer be feeding power to the white
circuit.

Or you could manually operate the anti-run-on valve.  (Oh, um never mind)

Cheers

Dave
