 Posted: Tue May 04, 2010 4:53 am Post subject: Ignition switch failure? |
 |
|
Hey guys,
Got my car running again this week, but it seems to have developed an odd problem. So what is going on is that even when the key is out of the ignition, the accessories stay on, like the key is in the run position. Everything seems to work, but I cannot turn the car off with the key. Does that sounds like an bad ignition switch?
And another quick question while I have your attention- Any good tips to allign the hood? Mine keeps getting stuck and it wont pop.
Thanks,
Ryan

When I replaced the turbo hood on Spike in lieu of a '77 hood for the intercooler air scooper, I had a hell of a time getting it to fit. The first time, I slammed her down, she fits! Nope. Had a really hard time getting it open for the first time. I adjusted the rear bolts near the windshield quite a bit. And, I watched how it latched up front. I think I was able to adjust that mechanism as well, I think, will have to check.

It may be the switch... but there is a terminal on the back of the ignition switch that goes live only when the key is in the off position, it goes to the side lights via the indicator stalk for parking lights. There may be a short between this circuit and your ignition circuit. When the key is on, and you put your indicators on, do the side lights come on too?
But in the US i think your turn indicators and side lights share the same bulb, (twin fulfillment bulb?) Not sure as in the UK we use white light as side lights and not amber so they are separate.
Anyup, if you do have the twin fulfillment bulb set up for side lights and turn indicator, your fault may lie in the bulb itself.
I had a fault on a car once, (not a Porsche) where... when you put your foot on the brake peddle, the headlights came on too. Took me ages to find the fault but that was a twin fulfillment tail bulb. Some cars use these for stop lights and tail lights (21/5w). The bulb had blow and the filament had shorted out two of the terminals inside the bulb so... when you put your foot on the brake, the the brake circuit fed the tail light circuit. As the tail lights and headlights are in parallel, the headlights came on too.
that lot should give you some good starting points. Good luck and [post what it was when it is sorted so we know for future.
Also how do you shut off the engine? forced stall?
Don't pull the battery lead off with the car running, this could damage the alternator.

9xx girl,
Yeah sorry I use that expression a bit too much, and too loosely evidently. "Hey All" might be a better one.
Right now I am pulling a wire which goes to the distributor. Works ok for now, not driving it regularly because of the impracticality.
The reason I think it is the switch is because I was wiring in a radio recently, and had the battery in the car to make sure I had it all working right. everything was working right with the key in each position.
Any way that crossed wires at the starter would cause this? That is the only thing I had touched electrically before the issue started.
I was also thinking maybe the bit that the lock tumbler fits into is stripped, or rounded out, and is just stuck in the 'run' postion.

In the US cars (not sure for ROW), when you have the key in the ignition, there is power to the radio and maybe some other interior things. Take the key out and the radio goes off. Ignition does not need to be on for the radio to work.
Might want to check that circuit. |

Alright, found something interesting.
When I take the key out of the ignition, the car still stays running, except, the headlights turn off. Only the headlights though, the buckets don't move.
Anyway, I will look into it a bit more tomorrow.
Ryan

This is true, having the key in the ignition energizes the radio relay (under the dash to the left of the heater controls on a RHD car). This relay also controls the sun roof as well as the radio. But from what you are saying, it sounds like the ignition switch. Take it out, you need to pull the plug from the back of it and remove the ignition lock, (this is well described in the Haynes book) and take off the switch.
You may be able to take the switch apart but i think i have seen this switch on early VW golfs and polos. There is a lock that looks the same on my "I SPY" post, so go rooting round you local scrappy and see if you can find one.

| StienbargerR, I have the same problem on my 924 and it isn't the ignition switch. We put a new one in and it didn't fix anything. My also stays running when I take the key out. Although once in a while she will shut off. If my father and I figure anything out I'll let you know. |

The park light circuit and ignition circit have to be shorted together some how. Are you sure all lights work as they should including parking lights StienbargerR and doiron?, Hay, you both have cars Mk 1 924 (1976-79) yes?
or Mk 2 1980-85?
hmmmm.... this is a good one 
May be a fault on the fuse board.

| Yes 9xx Girl, I have a 1979 Euro 924. I do believe that all lights are working as they should. At the moment I'm at College for the week so I'll ask my father to go check this week if the lights are working normally. It could be the fuse box, we had trouble with it a few years back. |

Just tracked it down! Long story short, what was going on is this- The main lead from the battery was touching two terminals on the starter solenoid.
Evidently if the main power wire connector is mispositioned it can touch the other terminal on the starter (upper one w/screw) This clearly by passes the ignition switch.
Anyway, I just turned the wire connector bit a 40 degree to where it was no longer near the other terminal post.

Thanx for the post,
Yep that would do it i guess, back feed through the starter soilnoid wire. hmmmm..... the ign switch must ground through the starter solinoid when it is in the off position then, hmmm, i will remember that one, good deducing Stienbarger
doiron, let us know if yours has the same cause

That's interesting. I was wondering how that was supposed to work. My radio is wired to constant power by some half-competent installer a previous owner hired (there have been several similar botches). When I get a round tuit, I shall investigate that trick.
