burnt out earth wire near ecu ....

[Jay09]

Last year my car got stolen and recovered and they stuffed the alarm, i got the car going by bridging the startor motor and that was all fine, then i got the alarm guy to play with the wires and put in a dummy alarm so i can get through the imobilisers and so i can turn the car on using the ignition, i also just put the battery to the boot, but hadnt ran the car yet

Any way today i tried starting the car with the computer plugged in and link software going, i tried starting the car and it took ages to crank then i noticed smoke coming through the ecu cover pulled it back and the earth wire had completely burnt all the insulator on that wire, but it only burnt it up to the junction where one earth goes to the ecu ajd the other to the bolt that bolts to ground, no wires are cut or earthing out that wire , looked at the ecu and doesnt look to be any damage,

Its really weird because before ingot the alarm guy to do his thing i couod start the car fine off the starter motor but now yeaaah. ....

is there anyone that knows a bit about electrical? and can help me

Also link software said warrning system below 7v

Car is a version 4 gc8

Have you earthed engine properly? As with batter in the boot then if you havnt your starter is drawing currant through ecu
