My ed falcon has been having park problems intermitingly for a while and now it wont go at all, i thought it was the TFI module on the dizzy but a new dizzy did nothing, i've also replaced the coil to make sure as well as the ECU but nothing has changed, one od thing is im gettin no constant power to my head unit until i turn the ingnition on and even then its only givin me 1.6 volts. does anyone have any idears?? please help.

main fuse in the engine bay?

nah, i've checked all fuses and fusable links in the loom also, all fine. it's got me stumped...

ignition barrel? they can cause problems also...

unsure if current passes through for the memory wire tho.. but it may!

(the casing with the contacts on the back of the steering lock/switch comes loose)

oh true, i didn't think of that. do you know if ya can test em or where i might be able to pick another one up from?
