92 civic deck/clock problem
K so i installed a deck harnes into my eg hatch and now the clock wont work. Or it does work but its very very dim and gets dimmer when i turn the headlights on. So i figured blown fuse or something. Turns out the fuse for the deck/clock is blown so i replace it, doesnt fix anything. So then i searched on here and read a post with a similar problem so i checked the under hood fuses and 1 was blown (Back-up fuse). so i replace it and still nothing.
The deck is getting 12 volts with key turned to ACC and the memory wire is getting 1V with car off and 4 with car on. All the wires are secured properly etc.
Now the weird thing is when i plug the harnes into the deck the deck wont turn on but with the harnes halfway into the deck the clock will illuminate fully.
Whats the problem here cause im stumped?

ok another thing, the clock will blink when the turn signals are on.
Nothing has been touched with the electrical except installing the harness for the deck. The only other thing was i had a new clutch installed but that shoould have nothing to do with the clock and deck.

you should not be getting 4v on the memory wire
it should get 12v all the time so you def have a wiring issue, almost sounds like a short the way the clock changes intensity like that
check the current draw on the memory wire soo if its drawing excess current
was the wiring intact 100% or is there signs it has been hacked or modded before

im almost 100% sure the wiring is right. The harness power is correct as is the ground wire and the acc wire is right aswell. The only other wire that makes a difference is the illumination wire and thats done right aswell so i dont know what the problem is.
might just start taking wires apart until the clock comes back on working properly.

so let me clear this up
before you installed the cd player the stock one and all wiring was running perfect...correct?
after you took the stocker out and installed the new one you blew both fuses in car andunder hood...
now you replaced them, did everything run fine after that... BEFORE you put the new cd player back in, or did you not test that?
If everything checks out, it just leads back to a faulty wiring in your new deck, or internal ground in the head unit
what you can do is take the deck and harness out and check for continuity between the memory and ground wire
if that checks out, turn your MM to amperage mode and run it inline on the memory wire with te deck off and see how much current is being drawn

basically the person who owned the car before me had there deck stolen. THe thiefs ripped the deck out and ripped all the wires off from the deck harness where they were attached to the oem wires.
This had caused a short with the illumination wire which blew the taillight fuse awhile ago. I fixed that and everything has been fine since then.
So i installed an replacement harness (oem male connector) to the wires that were there. Basically i went by the honda manual i have because the rear and front speakers are not hooked up so i couldnt check them with a 9V. After i wired the harness the clock will not illuminate all the way. I thought it might be short but it will only go full bright when the harness is halfway in the deck. I have jiggled the harness every which way aswell and that didnt make a difference.

try taking the illumination wire off the harness all together and see what happens
do you still get 4v on the memory wire even with no deck installed at all and just probing the OEM harness

yeah im testing all the connections without the deck installed and thats what im getting.
OK so here's where it stands now, i just spent 20 minutes outside taking apart all the wiring and nothing changed except i accidently shorted the power wire and had to replace the fuse.
So anyways the memory wire still only gets 4V with car on and 1V with car off. Illumination wire does 13-14V with car on and headlights on, power wire gets 13-14V with car running.
Now here's the weird part, 2 of the wires are reading .6xxV. Also when i had all the wires apart if i touched the illumination wire to the memory wire the clock would light up bright with the headlights but go dim with the headlights off. IF I touched the illumination wire to the other wire (didnt check exactrly which one) the clock would light up bright with headlights off and dim with headlights on.
I am really freakin confused, i just wired up the power, illumination and ground cause i know those are right.

yeah i was thinking it might have something to do with the alarm. I am gonna test the memory wire in the engine bay and see whats going on. I may just have to run a new wire cause i have no other option really since the wire is only getting like 4V's with the car on.

well the fuse that the memory wire is connected to is blown again so its for sure shorted/grounding out somewhere. Not sure how ez it will be to trace the wire so im wondering how hard it would be to attach a new wire to the under-hood fuse box.

yeah forgot about that, just gotta find out what things in the car rely on that fuse to stay power while the car is off. Dont have a helms for this car so if anyone can help me out the wire is white with blue stripe.
So far i know it doe the clock and deck.

before you do it, did you see which wire the alarm brain uses for memoery as well? maybe its tied in..
just probe with your MM on the fuse panel
there should be a few unused male spades stickoung out around the actual fuse location some are alwats 12v
