faulty loom?

[nxka24de]

has anyone ever bought something like a HU n the loom was faulty?

i have a new 7"TFT screen which turns on but screen doesn't motorise out. the loom supplied only has three wires; batt, acc and ground. i have taken it back the guy that sold it to me who plugged it directly to a battery and it motorised straight out which was kind of embarrassing. the theory was that there wasn't enough current to drive the screen motor so i did some re-wiring. i got to the point where despite repeated changes, it still wasn't goin n i had both acc and batt wires directly to the battery and the ground screwed directly to chassis (more than one location).

now, seeing as the seller showed me the screen obviously works and i am convinced it cannot be wiring, the only option left is the loom.

i don't want to go back and embarrass myself again so i'm checkin with u guys, is there something stupid i've overlooked here?

You're sure you have the right power/accessories?

Are you talking about the loom of the actual unit? If so, how did you connect it to a battery without the loom plugged in? Or are you talking about the loom of the stereo that you have jacked into?

There should be enough power getting to it if you are just connecting it to the stereo wiring... I would just run a new constant power straight to the battery, and get the accessories from the key barrel.

when you get the rb26dett you get more power into your audio system.

yes.. to clarify, the loom i'm talkin about is the one that came with the screen which is jacked to the back of it. i am guessin it is somehow faulty as i reckon i've tried everythin else.

There should be enough power getting to it if you are just connecting it to the stereo wiring... I would just run a new constant power straight to the battery, and get the accessories from the key barrel.

i already ran a new 16gauge cable for constant power direct to battery (spliced off 4gauge amp power with a distribution block) cos i thought there might not be enough current from the factory stereo loom. i have acc spliced off cigerette lighter but i previously had it also wired direct to battery to check but nothin...

when you get the rb26dett you get more power into your audio system.

i considered that... but i'm about $10,000 short... maybe next month  thnks chr1s.

hahaha

shit duuddeee i thought u were xxxx

get a test light into the connections while loom is plugged into the deck, make a note of the brightness of the test light, or better still, use a multi meter

So if its the loom with the screen, how come it worked when the seller put it onto a battery?

you're saying the guy at the shop used your own wiring loom or one that he prepared earlier? if he did then i'd say your accessories wire isn't giving you any signal at all.

Try it with the engine of the car running. The higher voltage might help it along.

If you read the first post he said he wired both the battery and acc straight to the battery to bypass the acc stage and still nothing happened.

My suggestion would be without using the stereo unit check to make sure you are getting sufficient voltage to both the battery and the accesory lead you are connecting to when the car is running. If not maybe you are using the wrong grounding spot?? H
Have you removed all the paint from around that area?

Yea, tried that...

when i brought the unit back... i couldn't be bother unwiring the loom cos it was raining so i unplugged it n used a loom the seller had on hand...

both of the grounds i've tried are holes that i've drilled through the metal supports behind the centre console... at one point i even ran a wire back into the engine bay for a proper ground in case that whole section isn't grounding properly...

i'll go to a mate's house who's got a multimeter tonight n check the voltage across the wires i'm connecting to plus the connectors on the loom... thanks guys.

If it worked fine with the seller's loom, I'd say it's a problem with your loom.

[nxka24de]

well... i checked connections on the loom, the voltage and current on my wires n battery. even wired the unit to my mate's soarer... nothin.

basically stumped. time for the professionals i think. off to an auto electrician for me.
