I have been having an electrical problem with my Z. If left unattended, the battery will slowly die. The process usually takes couple of days to kill the battery if I don't run the car.

I think I traced the problem to a relay under the hood but I can't tell what the relay is for, so maybe someone here can help.

When standing on the passenger side of the car and looking down into the engine bay and the relay box, it's the relay that is on the top left of the box.

or

The relay in the corner that is closest to the battery and towards the engine.

Marked on the side of the relay is the following "25230-P7100" and then "MR3-1011". and underneath it it reads JEDCO of course with the # "810" in ink.

 

Here photos are worth a thousand words.

 

Welcome to ZDriver! Rule #1... buy yourself a Haynes Manual.

Here's a scan from that book:



Looks like it's your lighting relay... do your interior lights stay on all the time? Is your hatch / doors closed all the way?

 

Thanks!... I got the Chilton book, maybe I need both.

That helps a lot, thanks!

 

Out of all the service manuals available, the Chilton's is the absolute worst. Tons of misinformation and inaccuracies.

The best combination is the Factory Service Manual (FSM) and the Haynes manuals.
