on/off instruments
 

Please Help with the electrical instruments in my dash board when I'm running my car, try to accelerate, or fall in a street hole, all the electrical supply goes down for seconds and return back; I review all the electrical connection, fuses, and relays, but continue the problem

These types of problems can be tricky. I would suspect that you have a common ground wire that has come loose. You may need a schematic to trace this and then a lot of patience to find it.

Are all the dash lights going out then coming back on? If so, that may be a loose ground.

Good luck.

You need to put the car year model on your signature

As an example, these are the ground points for a 1990 964. Look for the instruments ground MPXV.

If it's not the ground, then it's a loose power wire.

Check your ignition key socket. I have a problem with the contacts. When it's running sometime the radio cuts in and out, so does the A/C fan, and headlights. Wiggled the key in the ignition and it's the culprit. Now I need to find out how much it cost to get a new ignition switch and rekey it :(

thank you buddies; my car it's a 964 american roadster 1992; I'll review all this items and buy the ignition swicth from pelican parts for 87 $ because I live in Venezuela and I'll travel to US soon to pick it up; I;ll let you know what happens. my best regards

:(THIS IS AMAZING. THE ELECTRIC PROBLEM GOT WORST. TODAY THE MECHANIC INSTALL THE NEW STARTER SWITCH AND THE PROBLEM COMES AGAIN UNTIL MY CAR SMELL BURNED AND ALL LIGHT AND ENGINE WENT OFF. THE BATTERY AND CABLES GOT VERY HOT. DISCONNECTED INMEDIATLY AND CHECK THE ENGINE AND GUEST WHAT? THE ENGINE CARRIER AND ENGINE MOUNTS WERE BROKEN.

THE ENGINE IS ALMOST IN THE FLOOR AND I GUEST SOME CABLE IS TOUCHING GROUND CREATING A SHORT CIRCUIT

I NEED TO FIND THE ENGINE CARRIER PART NUMBER 96411502190 AND THE ENGINE MOUNTS. PELICAN SAYS THAT THE DONT HAVE THE ORIGINAL ENGINE MOUNTS, BUT THEY HAVE THESE ONES PART NUMBER 993-375-101-80-M285 AS Engine Mount, Solid Type Sport/Race Version. COULD IT WORKS??????

You don't want solid race mounts. The part listing 965-375-049/050 are correct for the 993 fitment.

For half the price, I recommend the Wevo mounts with blue pillows.

The engine carrier is P/N: 99311502190 and is a special-order part.

I will merge this with the engine mount thread...

Also happened to me... had to tow the car for 100 km... :(
Have a look at Rennline's site, they make a good reinforcement solution.
