New member, 1972 does not stop Options

[acebee]

Hi Forum Members

Just joined the forum today..this is my first post on the 914world...

please forgive if this is not the correct place to ask the question..

i had purchased a 1972 ( Dec 1971 build on the data strike plate ) and have used it for an year without any problem..

It has a 1600 or 1700 cc displacement..not sure which..with dual webber 40 IDA setup with computune & pertronix coil for ignition

most of the electric stuff seems stock for carb setup it is .. being smog free most of the other electrical stuff was removed..like buzzer, seat belt warning et all..

the car does not stop..when i turn the ignition switch off .

i had to pull the ignition coil to dizzy cap wire & then disconnect ground from battery to stop the running facet fuel pump

seems there is electrical feedback in the system..

should i have to replace the ignition switch and the voltage regulator ( bosch stock version with the yellow tape ?).. does the order matter..

Is there any other gremlin.. the real culprit ?

Fiddling with the electrical system can result in very strange problems. I wound up with a car that would run as long as the left turn signal was on. I caused it by using the wrong type of light bulb (single-filament instead of dual) in the left taillight bucket...

I can attest to that. I removed all the exterior lighting from my first 911 to refurbish the housings. I thought I'd remember where all the wire connections went, so I didn't label the wires.

A few months later when I reinstalled them, had a strange issue pop up. Now, this was 40 years ago, so I don't remember exactly how the sequence went, but IIRC, the ignition was in the on position, parking lights on, left turn signal on, foot on brake pedal, clutch pedal in and shifting into reverse - the engine cranked over (IMG:style_emoticons/default/yikes.gif)

Good thing the car was on jack stands.


Ended up being incorrect tail light wiring that cause the oddity.
