Re: 1975 hornet electrical problems

A: Sounds to me like the ignition switch may be cracked or worn inside and 
the alt is going offline at the partially turned point, which cuts down the 
drag on the motor, allowing it to rev up.

Hello all,
            I have a 1975 2dr hornet . 258 auto with air tilt and cruise.
I replaced the cracked exhaust manifold yesterday.
After starting the car and checking for leaks I go to turn the car off.

Now as I turn the key off the engine shuts down. fine.
If I turn the key slowly. just before the key shuts the engine off and I
hold it in that position
the engine increases RPM'S.
if I move the key forward the rpms return to normal.
I could possibly live with this.
At present I have a 1980 Tilt column installed in the car from a concord.

NEXT problem is with no acessarys on just the engine running.
If I remove the positive battery  terminal the engine increases rpms
signifcantly.
(400-500) RPM approx.
If I have the lights on  and remove the positive battery post the rpms
increase a little bit. 50 RPM maybe.
When I swapped the exhaust intake I did replace the cruise control Rubber
Bellow as the old one had a leak.

It was 11.00PM last night when I  Finished.

Any quick clues  before I dig in .
Thanks

Bryan
