Hi sir,
Thanks for your reply , Sorry but what do you mean by grounding problems ?
Do you think its something to do with the battery ?
I dun think its the ICE that cause this , because i've had the ICE install 2 weeks before the warning lamp lights up and everything is fine, and only after i change to a new battery for 1/2 a day , the warning lamps lights up .
Before they install the new battery , they had to cut off some of my wires attach to the batt cos is not long enough , and later extend the previous wire with some lose wire so that its long enough to reach the batt terminal .
I suspect this is where it trigger the warning lamp , anyway tks for pointing this out , at least now i felt more convince if its the grounding problem .
Hope you can tell me more about the grounding problems .
Best regards
