VE V6 Omega not going! Holden mechanics help please!

[mrv8]

Hi all,

We have had a VE v6 omega towed in this week. It had a flat battery, fitted new battery but wouldn't start, or even crank. Alot of the accesories also wouldn't work. After a while on the scanner, we reset all the computers and it started, and ran fine. Everything worked well. Then the owner asked if we could put a heavy duty battery in. Now the same problem has come back, but now we can't reset the computers. No fuses are blown, and have checked the common issues, like the wiring to the wipers etc. Any help would be much appreciated, as even the 2 local holden dealers, which we have a great working relationship with, are also stumped.
Many thanx in advance for any help offered.
Anthony.
