Electrical issue Porsche 914

[tedsu0]

Hey,

sorry for my bad english....

I have a 1971 Porsche 914, i have some issues with the electric system.

I think there is something regarding the ground.

When i put the car i revers(activating the reverslights) og break(activating the breaklights) the tachometer, oilpressur og fuelgauge dies.

Some idea what i could be?

Welcome to the STF!

Strangely, I vaguely recall having a similar issue many years ago...

Fuse does not blow, right?

There is a common multi terminal ground under the dash just behind the fusebox check that for fallen off or loose connectors.
If nothing there, could be the backup switch or wiring on transmisssion related.

(I have 74s, yours may differ some)

Iv been reading here for some time, seem to be the right forum for me.

Ill check the ground under the dash.

You know a place to find a good wiring loom drawing? The one in my haynesbook is not that good

If you have had "water in the trunk" issues it could also be related to the grounds to the rear lamps.
