Grounds Please

[Ravins]

Hi just wondering if anyone has a wiring diagram of all the grounds under hood and inside the car and were they are located for the 87 325 ETA motor

Under the hood, Behind Left headlight on fender
Passenger side strut tower
Oil pan to Driver's side frame rail
Those are the major ones, then in the car, there is a main one under the steering column. For details you'll need to get an ETM.

Don't forget, he has an ETA so the main engine ground on the strut tower on an 'i' is actually under the intake manifold next to the diag connector on an ETA.

On the older ETAs and cars with rubber alternator bushings there is also a ground strap from teh alternator to the engine block.

ETM whats that also is the ground inside for the ECU because I need to check the grounds to that too

NO ECU is grounded threw the engine harness to the block by the Diagnostic connector like stated. ETM is the factory Electrical trouble shooting manual, search on ebay or go into to your dealership to get a copy. It has wiring diagrams for every system along with where grounds and connectors are located.

If you read properly that's not what I said. I said the ground is not on the strut tower on ETAs it's on the intake manifold.

The alternator ground is attached to the block.

Check the Bentley if you don't beleive me, they are all listed there.

I know, just stating it differently, it's grounded at the Diagnostic connector threw the intake manifold, to the block, then threw the block to the oil pan, then to the chassis frame rail.

Sorry I was actually reading your post differently. I thought you were saying that "No Ecu" was grounded like that rather than "No, the Ecu".

Fucking internet, so easy to misread people.
