I did forget something, when my parking or headlights are turned on the car beeps constantly at me.

Is this when driving or not?

Well when I had to start deflooding the car everyday for a week I realized something was wrong. So I had to do that procedure about 15 times, and this was before I read to pull the egi inj fuse and the egi comp fuse. That and when restarting once in awhile after deflooding the tach would not work and the car would beep only while in motion. Now its the same beep, just it happens anytime my headlight switch is on moving or sitting still.

There's a warning unit in the CPU which reminds the driver when the lights have been left on. The circuit is powered by two fuses, and one is the Meter fuse so perhaps this playing a role in your problem.

I have more electrical problems in this car I still haven't figured out either. Maybe its related so I'll share. The room fuse has been a problem. It was popping everytime I've tried to plug a fuse in there since i bought this 7. I havnt tried to plug one in there in awhile since none of the stuff seemed to important at the time to keep the car running. Just had to many other problems to get to it. But tomorrow i will plug a fuse in there and see if some of the grounds I've cleaned/replaced may have fixed it. But its probably in the cluster **** of wires in that kick panel/ under dash area. Looks like the po got in a hurry when rewiring her after the rebuild. A few connectors and plugs are not properly fastened like how it is in my other unmolested 7 in the garage.

It's nice that you are now sharing this information. This is not how it is done. You need to look at the online wiring diagrams and go from there.

86rxNa

Well I don't know any other way of doing it, I just do. My other car getting fixed so I'll be able to park this one soon and actually take some time to go thru the wiring diagrams. Just would be nice to see my rpms in the meantime.

Still reading .21v w/key on.

So, either the B/Y wire has come loose from the fusebox and or the wire has grounded out and causes the fuse to blow. If you want to check the wire to see if it grounded out then take the meter set to continuity and w/the largest CPU plug disconnected place one meter lead to the back of the B/Y wire so the meter lead is snug and place the other meter lead to a good ground and if the meter rings out then you know the wire has grounded out.


And your initial post only mentioned the gauges not working and nothing else. No mention of the Room fuse and so on.

86rxNa

Ok, what do you mean by if the meter rings out? Ty for all this info.

86rxNa

Should I disconnect the battery to test this?

satch

Ring out means the meter makes a sound similar to a low oil buzzer. It is loud and you cannot miss it. And the battery doesn't need to be disconnected but you don't put the key in the ignition either.

And in the three hours which passed between my post and your reply was there not an ample opportunity to watch a video or two from Youtube illustrating how to use a multimeter? The info is free for the taking and it appears it wouldn't hurt to increase one's knowledge about things, especially since the car, which is not operating properly, is yours.

Ok so its not ringing out, no buzzer. I get a reading of 34.4. I checked both ways by sticking the probe in the back and in front like in the pic with same results. The fuse hasn't blown since earlier this week when the I first reported the gauges dying. I'm sure I put that info in there. When I initially checked the fuse it was blown and has not since.

If you have the meter set to continuity and you place both meter leads to each other then the meter will ring out. Does it? Secondly, make sure you are using a good ground for one of the meter leads.

86rxNa

Ok looked again and I think im testing wrong.

86rxNa

Ok i got the meter set to continuty I had it on resistance. It does in fact ring out and beep now. So if the wire is grounded out what does that tell me?

satch

Did the meter ring out when the meter leads were placed together or when you checked to see if the B/Y wire is grounded out or not? If it was the latter then you need to inspect the B/Y wire and see if you can identify the problem area. The wiring diagram indicates all the items powered by this fuse (meter fuse) and which harnesses are involved. You know the B/Y wire starts at the meter fuse and runs to the largest plug in the CPU so that would be a place to start. You can sometimes jiggle a wire if it looks suspicious and then do the previous test again and see if the meter fails to ring out.

86rxNa

Yes the meter did ring out with both the leads touched and when I tested the b/y wire. I'm gonna see if I can trace that wire back tomorrow. I looked at the wiring diagrams for awhile, they are somewhat confusing. I'll keep reading I am determined to sort this out.

86rxNa

Still no luck, poked around for 2 hrs yesterday. I read in some other thread where a guy bypassed the connectors and hooked the tach up from the trailing coil. Can this be done temporarly? Also this b/y...is it the same b/y wire I see going diff places under my dash. Like I see one in the connector for the brake switch. It had same reading of .21v. I checked a few other spots I seen it and got the same numbers. Does the reverse switch have anything to do with this in your opinion?

satch

The reverse switch is powered by the B/Y wire. You can try unplugging the switch and retesting the wire as you can also do this to the other components supplied by the B/Y wire.

The B/Y powers all the gauges except the speedometer. This wire does not provide the signal to any gauge but just supplies the power so you need both a signal to the gauge plus a voltage source so unless you take care of the B/Y wire your gauges will not work.

86rxNa

Sorry if I keep asking dumb questions satch, but take the reverse switch for instance. Its highly unlikely I'm getting under there for that one but in theory if I disconnect it, do I go back to the largest CPU plug and test from there? And would I need to disconnect the cpu plug to check continuity as I did earlier on it. And if it doesn't ring out then I know I've found the connector or circuits that are grounding out?

satch

If a component is shorting out the B/Y wire, then if disconnected, in theory it should cause the B/Y wire to act as it should which would mean 12 volts w/key to on at both sides of the meter fuse. The B/Y wire runs through FE-02 before reaching the reverse switch so use the wiring diagram to find that connector and unplug it. Remember, the B/Y wire also runs to the gauge cluster so that to would have to be unplugged, at least as connector ME-01 is concerned, which is one of the two round plugs located at the back of this cluster. FME-01 is the intermediate connector before ME-01 and after the meter fuse so this plug could be unplugged instead of ME-01.

EDIT: FE-02 is located near the trailing coil and the plug has 5 or 6 wires in it.

Alright sweet, well at least a few things I can check now. I've been reading the wiring diagrams like crazy so with this info I think I'm heading in the right track. I also have noticed my warning lights are out too. I'm going to try n find everything that's hooks to this meter fuse and see what's still working if any of it. And maybe that plug by the trailing coil is loose, I have switched the coils recently(not the same day or week of this problem though). I also have played with the aas switch recently to see if it worked(not since the guages have died though), I think its part of the meter fuse too. Well it seemed to work, I heard something going on when I hit the switch from sport to norm. I won't rule it out yet though. Thanks again satch.

86rxNa

Well I fixed it, its only been 10 mins so I still got my fingers crossed. You gonna laugh ur *** off, all I did was put the room fuse in. I've tried to put one in their before but it kept blowing, so I gave up it. Now this was months ago maybe even a year ago. Since I've been cleaning up wiring issues and cleaning grounds, it looks like I got it. I put the fuse in and I was expecting it to blow. When it didnt I'm like wtf. Turned key to start and everything came back on. This was without the meter fuse in. So I put that one back in and nothing blew yet. I guess only time will tell. But ty satch I learned a lot about electrical stuff this past week or so. Sorry I didnt try this earlier as I coulda saved both of us time.
