Emu power up trouble

[FeNder]

heya everyone ,

after taking out the harness + field for inspection , i put it back in place without changing any of the wiring , however the the emu wont power up when ignition is on , all jumpers in place , all wires connected , dash lights come on , where might the problem be ?

its gotta be your power wire has got knocked off where its spliced into the extension harness?

have you had it back out to check since finding she didnt have power?

yeh its all out there on the seat anyway , i had a second look it all appeared im place , will have another look tomorow in daylight !

 

[FeNder]

okay i got the harness/extension on my desk , everything is spot on , the 12v red wire joins the power wire pin 9 on the smaller connector together with the adapter wires ,
therefore the power isnt reaching either emu or the stock ecu ,
which fuse or wire should i be looking for ?

it might be a long shot buddy, but have u looked at the efi fuse?

kon

well i didnt check of the smaller stock plug itself had the power wire knocked off , or any of the fuses yet , will i find the efi fuse in the main fuse box in the bay ?

yes

right what else could it be , on cranking the car sometimes cuts out completely as if theres not batt connected , its fully charged ,
maybe its an ignition barrel thing , no switched 12v ignition , to the emu aswell ? started shortly after wiring a turbo timer , im suspecting its circuit shorting trouble ?

 

[HYBRID]

one last thing.. what version emu do u have?

 

[FeNder]

B version , i checked inside the ignition chip has the white tape over it in place

 

[HYBRID]

hmm... take the board out & have a look at the bottom ignition chip ie from underneath.. i have this weird feeling that could it be ur problem buddy..

Hi,

Try checking your ground wires on the EMU, might be your problem, if that doesnt fix it drop us a PM and i'll go through it with you.

Many Thanks

grounds are fine now after removing the intrusions ,
the fuses in the bay are all okay ,
where else is there a fuse to look for that can supply the 12v switched for the ecu and emu !
