The wiring for the deck in my 1988 Jetta is all hacked to hell. I have went on the Advice of Ross and install dr to connect my deck, and it does not power on. I tried my Alpine deck and my Clarion, both decks I know work fine.

I do not have a test light on hand so I cannot test. What are some other methods I should use to trouble shoot?

check your fuses
all of them under the hood as well as under the dash

checked, I will recheck in the morning in case I did miss one.

take your 12 constand and your ground wire, and touch them both to your tongue.... if current is flowing through them, you'll know!

Not sure if this applies to an '88 VW, don't you have to connect the full-time and backup power together to the deck? The VW's usually allow you to turn the deck on with the keys off, so with an aftermarket one don't you tie the two power wires together? [img]graemlins/dunno.gif[/img]

Yeah I think on that year of Jetta you have to go looking for an ignition power source. IIRC the fusebox is a frustrating waste of time - grab ignition from the rear defrost or something.

^^^Yes. I had an 87 Scirocco and had to do this.

if your key sensing feature still works(key in the slot but not turned on),use the small 20ga brown w/red stripe to power up your acc. wire on your deck. being a vw owner you would know you can put pretty much anything in the slot a get it to turn on the chimes.my wife has a 92 jetta and i hate those chimes. out with them!dont forget to add a fuse. also, test lights are cheap and good to have

^^^^ oh yah that wire will be at the back of the ign. switch.the only small ga. wire there usually

Tried that on 2 different decks, nothing happened.
