Never mind!
I hate you Dome 20A fuse!!
an LED light i installed in boot blew it.

Thank fck i have the camry manuals, thankyou so much whoever i downloaded them from!
life saver.

Well I've been reinstalling my stereo into my '90 cs and I go to turn the headunit on, and nothing.
Won't turn on or anything!

This is an alpine CDA-9884E unit that I have previously sent back to alpine cause the amps were cutting out randomly, they told me to get a relay switch, which is what I did.

So yesterday I started, mounted monobloc amp onto back of sub to clean it up, works fine with my pioneer head unit.

Today, I mount the 4 channel amp onto back of seat and wire up a relay for the amp power on. I tested this out with the pioneer head unit and it worked fine, both amps turned on, no problems at all.

Then I take off the negative battery terminal and install the head unit, changing the Pioneer to an Alpine. I took the pioneers power cable out and straight away connected the Alpines and heat shrunk the connection, did this for the ACC and amp turn on cable.
I mount the ground and amp leads then put the battery terminal back on, turned the key, push the button to turn on head unit and nothing!
Nothing happened at all, and now the digital clock, inside roof light and boot light don't work??

I've checked all the fuses and they are fine, the cigarette lighter even works (replacing the cig fuse month or so back fixed the cig lighter not working and the clock working).

So I am completely stumped! Pressed the reset button on the Alpine unit and double checked all the connections, but I have no idea what is wrong with it

Anyone have any idea at all as to what's happening?

btw, the car starts fine, cluster lights work, checked fuse on head unit as well and it's all fine.
Going to put the pioneer back in tomorrow morning and see if the Alpine is broken.

Thanks in advance

Small world, didn't know you were on Whirlpool too.

Are all the earths good? Maybe you've mistaken the illumination as a ground?

yeh im on wp, tried to get my user name changed here but no luck.

i got noise filters for the RCA cables for the 4 channel amp so hopefully that will stop the noise interference i had last time.
so tomorrow will finish hooking it all up and see how it goes.
post some pics up tomorrow some time.
cant wait till its up and running again.
