928 Battery Location

[intervol]

I have just inherited a 1984 928 for my sins and studidly cant find the battery! I have tried jumpstarting the car off the terminals in the engine bay by the O/S/F wing without sucess.

Please Help,

Thanks.

Might be worth rummaging around in the boot as I know for a fact late model 944s have them there, 928s could well have a similar arrangement.

Open the rear hatch, (you will have to connect a battery to the engine bay battery points).

Lift out the rear carpet.

Open the lid on the left hand boot floor. Remove spare wheel.

Battery is then under the metal door.

Good luck

Henry, you must be used to more modern 928s than me!

Open the boot with the key
Lift the carpet
Remove the corrugated plastic cover over the spare
Remove the spare
Open the metal door and the battery's underneath.

just as I said !!

They didn`t really change.

As mentioned, the battery is mounted in the rear of the car over the transaxle, to one side, accessed from the rear hatch.

Be careful about trying to jump start the car, as a miss connection can fry an EXPEN$IVE fuel injection module.

If the car doesn't start, next thing to check is the fuel injection relay.

good luck

From my period at Porker GB there were a few of the final fat gadget laden barges/928's stuggling to cope with the power draw so had a second boot mounted (I think) battery added.

As a previous poster said been careful charging!!!

Just a tip to a fellow (new) 928 owner, the 928 engines have no known weakness, if (and this is a big "if") you just maintain the timing belt. Of course other things wear out too, and the fuel injection relay should be changed "now" so you don't have to post a "help" note about the car not wanting to start, etc. later. They are $18 US and many people keep a spare in the glove box. The DOHC models are similar to the DOHC 944 models, the early DOHC heads need to have the chain drive examined from time to time, as they are not able to run forever without attention. (Timing belt drives the first cam, chain connection between cams drive the second cam on these DOHC models).

Here are the ultimate words of wisdom for a new 928 acquisition: "if you don't know the age or milage on your timing belt, you absolutely MUST bite the bullet now and have it changed, period" (no whining either, just do it, or you may be really crying later).

The timing belts are generally thought to be good for 60,000 miles, but age is a factor too. In the US the best advice is to run the car 50,000 miles "OR" 5-years, and then change the belt. Many people do the water pump at the same time they do the belt. Pay attention to the rollers too, and tensioner. This is part of the "pain" of owning a 928, but there are way too many joys having a big engine with torque and power all the way to redline to be worrying about the cost.
