Problems installing HU?

jmjacks · Post by **jmjacks** » Sat Nov 19, 2005 9:09 am

I am having a problem installing a CD player in my 90 chevy lumina avp van. I have checked the fuses they were blown & I replaced 2 of them. I have tried 2 different stereos that I know work & can't get either 1 to power up.

I'm almost positive that I have the correct wires:

Orange from van to Yellow on HU - Batt/Memory

Yellow from van to Red on HU - Ign/Acc

Black to Black - Ground

How would I test the wires with a multimeter I've never used 1 what should the readings be

What else can I do is there another way to hook up a stereo without the stock wiring.

Someone please help!

Buy the >$10 adapter from Walmart?

The batt/mem wire should have a power reading at all times, the acc/ign wire will only have power when the key is turned to the run position.

Orange from van to Yellow on HU - Batt/Memory

Try running a wire a wire straight from the batt to the cd player. I have a 92 chevy S-10. After a while the stock power wire wasn't constant anymore. I dunno why, but try running a wire straight from the batt to the cd player.

This is a test light. Go get one and test the wires.

All a test light does is check if there is power running thru a wire. I dont see how it would set off an airbag

well it places a current draw on the line to light the bulb....this is what can supposedly set the air bag off.......

i could see how it could if you were poking into the wrong wires. the ones in the yellow wire loom are the bad ones which should be no where near the radio.
