I recently bought a 1972 Porsche 914 (with a '74 2.0 motor) and have been having some electrical problems.
Ok here it goes:

When I turn the ignition on, as well as start the car, the hazard indictor lights on the dashboard start to flash and the relay clicks. The exterior lights do not flash! The hazard switch is fully disengaged!

Before I proceed, its worth mentioning that this is a '72 car. Meaning that the hazard indicating lights are in the FUEL gauge and the turn signal indicators are in the speedometer. When my problem occurs the speedometer lights DO NOT flash, only the hazard indicators in the fuel gauge.

All of the turn signals, hazards, and lights worked just fine otherwise.

So being a DIY type of guy I decided to order a new turn signal/hazard relay from AA. Having installed this new relay the problem got even worse. Now BOTH the the turn signal and hazard indicators in the gauges just stay (but don't flash) and none of the exterior lights work! And the thing is buzzing at me like crazy!

I have also cleaned the ground underneath the dashboard.

I am fresh out of ideas, so any comments, criticism, and help is much appreaciated!
Thanks 914World!
- Chris

The big red flashing light in the FUEL gage is actually for brake pressure. It relates to the pressure switch located on the side of the master cylinder. Could you be getting that mixed up?

What happens when you disconnect the hazard light switch?

The big red flashing light in that gauge is triggered by the brake master cylinder when it loses pressure.
This is common after bleeding brakes. There is a reset button on the drivers side of the MC that you need to push to reset the light.
Turn the wheels full lock to the right and crawl under there to reset.

The same light is also used as a parking brake indicator...

No, on the 70-72 cars the hazard lights are indicated on the fuel gauge. The 73-76 cars do not have these lights in the fuel gauge.

That is the brake warning light. The 70-72 cars have hazard indicator lights in that place.

No...this is different. These are Hazard indicator lights. Only available on 70-72 models. I am aware of the brake warning light, that is different.

Then post a pic of those "dedicated Hazard indicator lights" on your early car.

Yupp, as i said above, the MC pressure warning uses the same bulbs to indicate a pressure loss.

That goes for early cars too ...

These three go to those lights:

32 Brake warning switch
34 Hand brake contact
47 Direction warning blinker indicator (second page of the diagram, not shown here but indicated by the tiny 13 next to the wire)

I'd suggest reinstalling the original relay, then checking your master cylinder and parking brake.

Admittedly, you're right. What does this button look like?

That's the master warning light. It's normal for it to flash before the car is started.

It will normally light and flash due to at least:

- Alternator not charging (ignition on and engine not running).
- Handbrake on.
- Brake failure (brake warning switch).

I'm looking at the master cylinder as it sits in the car and I'm not seeing a "B" or anything that looks "button-like". I've also looked at an MC when its out of the car and seen nothing.
