Help please
Removed battery, cleaned ground.
Took battery to AutoZone for a load test.
Battery tests out ok.
Next day, put battery back in car.
When I connected it, trunk light came on.
Turned ignition switch to aux position, and guages came on.
Turned key all the way.
Heard one quick click coming from rear
of car,
the guages, lights, etc went dead.
And, of course, the engine did not crank.
John,
Why don't you take the car to your local repair shop?
This has been going on for over 2 1/2 weeks now...
Wouldn't you rather drive it?
I decent Porsche tech would have that diagnosed in an hour on his hoist...
And you know what they say about free advice??
Well free advice on the internet is only worth half of that.
That being said I can't sit by while you waste another perfect weekend working on it instead of driving it. So here we go:
Car in neutral
Emergency brake on
Go the the back and remove the black plastic cover off the electrical board. (very left rear of car)
Remove the 14-pin electrical plug (be careful not to break it-its 25 years old)
Now make a jumper wire (12-gauge) to bridge pins #1 and #14
(They are marked and on opposite diagonal corners)
If the motor cranks when you bridge 1 & 14 the starter is good.
If it clicks and you get a big arc at the jumper you need a starter.
If the starter works with the jumper and not the key you have insufficient current getting to the starter from the ignition switch and you need to find and repair the bad connection.
This is just a rough outline and there could be other factors contributing to this problem. Be sure to check the engine ground strap which is hidden under the transmission mount and bolts to a stud on the chassis directly forward of the right transmission mount.
BTW- If it does crank with the jumper and not the key, you can turn the key on, use the jumper, and it will start. Then plug the 14-pin connector back on and drive it into your local shop and you will save the tow.
Good luck
