Engine ground leak

[me2kimi]

Hi all zth'ers.

My charade ascend got a problem with wiring. This problem occurred after I replaced fuel pump.
The symptom is auto gearbox EASY light blink and gearbox act weird. A friend suggest me to add extra ground wire on gearbox and it work for one day.

After that the problem is still occurred. From my troubleshooting, what I have found is the EASY light only blink when there is electrical load, eg. turn on front light or aircon.
What I have done before is:
1-put back old fuel pump
2-add engine grounding wire
3-replace alternator
4-add ground wire to ecu body
5-replace radiator fan

Then what I found is, when I connect multimeter (to test ground continuity) from -ve battery terminal to chassis or other ground, multimeter beep continuously when engine is off. After engine turn on multimeter intermittently beep, which mean the grounding is not 100% connected.

I have took out fuses one by one during engine running but still cant find the culprit. What should I check? Please advice.

i still remember last time i got a nasty electrical shock while installing grounding cable on a g11 charade.the alternator body is live.
u hav an electrical leak and have to trace it.it will be a hard amd painful process.
