Switched Power Help!

[gatty]

ok guys - some weird shit is going on....

i pulled stock cassette player out of my 33 - identified wires and started to hook up - but unit wouldn't light up!

So i took it out and tested power wires again with test lamp - constant was fine - switched was fine....

Then i tried it again - no go...switched suddenly didn't have any power to it!!!

I dissconnected it again and it tested as dead once again, i tried to start car and it wouldn't idle - i had to give it some - turn the car off, then when i start it again it would idle fine!

So i test switched again - it was fine - as soon as i plug the connector into the back of my sony headset (that does work) the switched wouldn't work - thew second the connector left the back of the headset it would...

weird

any idea's?

Check your groud wire, or even ground it to the body of the car and try again. also make sure when you turn your car on the ground doesn't become live.
