Not really... but something similar. When I step on the brake, it cuts the current to the guages. Gas, Tach, Speedo...they all shut off. I just bought this car and haven't dug into it yet. I was told by the po that someone had installed BMW brakes on the front. Maybe they also put in a 19mm master cylinder. Not sure.
Has anyone had this happen to them? Should I look at the master cylinder and check all the connections for a short circuit? Where else could the trouble be?
I want to get this car ready to AX on the 30th, but the problem list seems to be getting bigger. It's good to be back in the 914 world tho.
The break switch is a ground path for that circuit. Somehow your gauges are either getting power form that circuit or a ground. Time to reads the spaghetti (wiring diagram) and use your meter
I have a similar problem. Everytime some jerk pulls in front of me going 30 miles per hour slower.Horn goes off just as I hit the brakes. The steering wheels mysteriously jerks to the right; then to the left; followed by the universal salute.

Fuse. I forget which one, probably #8 or #9. Pull each fuse out (one at a time so you can get them back in the right spots!!) and inspect it. Betcha one of 'em falls apart while you're removing it.
--DD
It is almost deffinately fuse 8 or 9, though I don't remember which. I had this happen to me on the way home from work on day. You also don't have brake lights when this fuse goes!
Your horn goes off when you hit the brakes? That's one hell of a practical joke...
Haha. I was thinking you should swap the wires and make it so the horn honks when you step on the gas!!
DAVE!! You pulled in that classic birthday photo for your avatar!! Nice.
I've been trying to compile a *complete* fuse chart for a while. So far, the best I have is http://www.4nets.com/baldwinpowersports/914fuses.htm.
I had a similar thing happen- but it wasn't with those particular guages....
It came down to having some wires having worked their way between the floor plate which holds the pedal assembly (I had replaced the original wood w/ a metal one with semi-sharp edges) and then them shorting against the body of the car.
Dunno if it could be a similar problem....worth a check.
This is what I did.
Took out all the fuses (oops, wish I had seen Dave's response first) and cleaned them. They're all pretty old, one in particular was corroded. I didn't have any spares to use so I will have to go buy new ones. Which brings me to this question: what fuse rating goes where? Is there a chart for this?
I looked at the master cylinder and everything looked okay there. I did notice a red wire coming out of the same hole as the brake line to the back which was actually cloth wrapped (like a fuel line). This was not connected to anything. I'll try to get pix of this.
Also, I noticed that the ground strap above the tranny came from the body down to the tranny ears. I thought this connected on top of the tranny.
Anyways, the first step will be to get new fuses.
Thanks for the responses.
Oh thanks. I can't believe I missed that. That will help.
Just to update. I put in all new fuses per Rand's chart. This did the trick. Now the guages don't cut out when I step on the brakes. And bonus, I have turn signals. The only bad thing is that now the flasher unit won't stop clicking, no lights, just clicking. One thing leads to another.
