Is there a fix for this switch rather than installing a new switch?
As you can see by the photo, that the tab does not stick out far enough to cancel.
Yes, the switch is turned "on".

wrap some electrical tape or heat shrink on the tab that contacts it .. fixed it on my 944

So, did your tab look as stubby as mine?
I will try your tip.
How long ago did you do this modification?
Its hard to imagine that a piece of heat shrink would last but maybe a couple to turns before the heat shrink would get knocked off.

the 944 is a little bit different maybe but i actually wrapped the actuator on the wheel , not that little nub on the switch .. worked for 8 years

Here is my actuator, if you're calling the plastic tab on the wheel itself an actuator.
So, you think I should put heat shrink or electrical tap around the plastic tab (actuator)?
Sorry for the dirty picture, I've cleaned it since.

theiceman

yup thats what i did ... look slike yours might be getting a little worn ..

bcgreen

Great, will try that.
I appreciate it.

Ice is the only person that I know of who has ever been able to repair these switches. I just replace them every few years.

theiceman

hey what can i say .. im cheap .. .. maybe i am so cheap i should be demoted to the 944 board..

944? You can bring some 944 M-Jetronic knowledge here.

I'm battling a periodic no-start. I'm thinking (after talking to Doug) that it's the fuel check valve. Fuel pressure was good yesterday, but reading 12psi today. Either the gauge is bad, or the check valve is sticking part way open. Fuel delivery is good, and mixture is .97 ~ 1.03 lambda. Anyway, I'll start a thread about it after the new check valve arrives.

May have to go with a new switch if this fix doesn't work. Isn't replacing them somewhat of a major undertaking? About how many hours on your first attempt at replacement?

bcgreen

About how many turns of electrical tape do you estimate I will have to apply for it to work?

No, replacing the switch is not that bad. You've got the worst part out of the way, which is removing the steering wheel. If you do go that route, then remove the light switch instead of trying to figure out the wires behind the dash. You'll need a pair of snap ring pliers on the switch retaining ring (to unscrew it from the dash side). Then let the switch hang down and replace the other plugs and stuff under the dash. Probably a 30-40 min job. Dont mess with the hazzard switch, just work around it. It'll break if you try to remove it.
