WIBIMMERS

AAAAAAAAAAAAAAND my speedo stopped working. Tap the dash and it comes back for a second and fails again. If anyone has tips on pulling the cluster and checking out everything. It would be much appreciated.

ooo, good idea! could easily be missed

i wish you were closer so i could look at this myself.

I found this on r3v: (they suggest to check the grounds)

I'm getting more and more concerned the ground got messed up in the process of all of this. All of the ground wires that I can find (3 of them 1 from the radio) are all connected. Any advice on re-grounding it them? 

My analog clock is still lit and working, but I don't have lights for my heat/ac controls. 

I am concerned about pulling the cluster and causing more issues.

Not much of a wiring expert, hint if you have your hazard switch installed upside down in an e30 which is possible by the way your headlights and turn signals will exhibit strange behavior...and there was that rewired 1955 Willy's Jeep kind of on fire incident in the mid-70s. 

That said: 

-If you're getting power to the head unit have you tried running a cassette in the deck to see if you get any sound from that? If yes could be just a radio specific issue which leads to other things. I don't know the unit but If no longer power to the head is there an inline or internal fuse?

-With the radio the clicking sound through the speakers is one click when you turn the unit on or constant? 

-As far dead dash lights which fuses have you checked?

-Also to rule out the "doh" factor with the new light switch have you rotated the switch knob to make sure things aren't just dimmed (been there I am sad to admit)? 

-Lights aside do the gauges themselves still work (tach, speedo). If yes that is a good thing, if no you might have damaged/shorted your SI board.  You have had the battery disconnected during the install yes? 

Yeah, I have tried the cassette deck. Still no sound. Cassette deck itself seems to be working. 

The speakers click once when the radio turns on and the sound is turned up. 

Dead dash lights (& PS rear Tail light) - I have replaced fuse #'s 10,12, 19, 21, 22, 23

I did rotate the knob.  I wish it was that easy! 

The speedo, tach, etc. all work, just no longer light up. 

Yes, I did have the battery disconnected.

Replaced the HL switch. No luck. 

Anybody have any insight into wiring troubleshooting?

DAMN! Something came up. I'm not going to make it.

I borrowed a speaker to attempt to see if I could get some sound out of the radio w/out having to remove any panels. Now, when I turn on the radio I can hear a click from all of the speakers. No luck getting any sound to the speaker. Also, no luck with the lights in the dash. 

The voltage coming out was .023 at the most. 

I'm thinking I ended up with a trash radio and killed my dash lights in the process of trying to do the install.

only one way to find out!

and just to be perfectly clear - there is no amp and location #3, hidden behind the carpet panel? and no wiring that has been cut running up inside the car under the seat/side panel between the rear speaker and location #3? there should be a big bundle (10ish wires) that would have gone to the amp.

and to go back a little, did you say at some point when you owned this car the speakers worked? what was changed/who changed it since that point?

I’m an idiot. I was looking under the carpet on the DS side towards the tail lights in the quarter panel. It’s there.

Yes, the rear speakers were working for sure with the old radio.

if all of the dash lights are dead that would normally come on when you pull the light switch to position 1, the light switch could have shit the bed or the connection came loose. any of the wire you were dealing with at the radio shouldnt have affected this, the only thing i can think of is if you were tugging you could have pulled something loose.

the amp wiring is gone? i've never heard of anyone actually pulling the wiring when putting in a new system, that would be a waste of time and rather tedious to remove from the harness. your car most likely never had an amp. do you have tweeters in the doors at the mirrors?

I was trying not to pull on them too hard, but there wasn't much to work with. Are you thinking it got pulled from the back of the headlight switch? 

I have one odd plug, but nothing that looks like the plugs I have found when I search for the amp.  There are a few loose wires back there, but nothing that matches the schematic. 

Yes, I do have the tweeters.

Speedo, Tach, Fuel, Temp & Climate Control 

All of the warning lights are still functioning.

I plan on checking the ground (it was a mess) tonight.  Also, none of the wiring that would have been going back to the stock amp is back there, so it looks like I'll be sending wires out for that.

I just picked up the amp. Hope to give that a shot tonight and see if I can get things working.

Took the car for a spin last night my dash lights are no longer working. Unbelievable. From what I've read they are part of the same wiring cluster as the radio

i've attached a photo showing the wires on the back of the CM5908 referenced below.

its seems like general internet consensus is that mystery two prong plug is not needed. see '??' in attached photo.

backlight wire should be the white wire in the 2-pin plug that has yellow and white wires. see 'IL' in attached photo.

the white wire for the antenna power: there should be a prong near the top right corner (f you are looking at the back of the radio)where this would plug into. see 'PA' in attached photo.

is the amp gone, like the wires are hanging around and its been removed, or it was never there?

see my attached diagram for explanation of the wire loops. it shows a wire being connected to two pins of the the same connector.

the etm diagrams are certainly another language until you have used them a few times to figure out wiring.

AAAAAAAAAAAND it isn't the fuse. Any ideas?

I'm down for driving from the Madison area.

My shop is on the east side and is always an option as a gathering spot if that sounds like a good idea to anyone else? I would say arrive between 8:30-9am and we can head out at 9am.

Unless something comes up count me in!

I know, I've gotta quit.

I'm trying to live my life a quarter mile at a time, but Jonny Tran keeps blowing up my NOS filled cars!

lol

speaker panel screw?

I think so. As soon as I saw it I immediately thought of that movie!  Hahahaha

I found this screw on my floor last night! 

If I learned anything from The Fast and the Furious I can pretty much count on my diamond plate flooring to fall right out of the car.

Anyone from Madison planning on going? I’ll be driving down to meet with the rest of the MKE guys at the park and ride.

@Jdesign @vbhargava @cpandrewschmidt @AlpineE30

Oh Man! I want to go! Let me figure out what's happening that weekend!

Clearly in need of some work, but didn't look too bad

Look what I spotted in the wild the other day!

Ran the car tonight for an hour and entered the code. Even with the antenna power and the (hopefully) functioning tape deck I'm not getting any sound. 

I found a thread about replacing the lights within the deck, but want to get some sound before I go through all of that.

Looks like I need to figure out the amp situation and move forward from there.

Thanks for the clarification on the diagram. This is my first run at fixing a stock radio using existing equipment.  

Got the antenna power attached, but the radio is now asking for the code and looks like I'm stuck in the hour waiting period.  

I was using that picture as a reference as well. So IL is going to be my backlight power? Damn I hope that isn't shot. 

As far as the amp goes there are wires hanging and it looks like the mounting brackets are there.  Part of me wants to just rewire the whole damn system.

straight6pwr said:

do you have the speaker wires from the back of the radio matched to the 8-pin plug per the etm diagram?

there are supposed to be two looped wires on that connector, per the diagram. A yellow/red loops from pin 3 to 4 and a blue/red wire loops from pins 6 to 7. That connector should also have 4 wires vanishing off into the dash headed to the amp. yellow/black, yellow/red, blue/black, blue/red

did you look for your amp yet?

you could run a temp. wire from the head unit outputs directly to each speaker to test the outputs of the radio/speakers.

what color are the two wires from that 2-pin connector? your phone pics are sized for ants. maybe its powering up a 6-CD changer, i believe this radio was capable of connecting to one.

is that white wire the power wire for the antenna, or is that accounted for already?

I am not seeing on the diagram where you determine that there are loops, but they are there in the plug.

The amp is gone. 

The 2 wires are White and Brown and Blue and Grey. They originate from the same plug ( +12V) as the Violet and Brown that go to the power distributor box (on the left side of the diagram). 

My backlight is not powered. I wonder if the 2 pin is for that?

I don't have a corresponding solid white wire coming from the rear of the radio.
