Predator programming question for 2004 H2

[jebia]

ChuckE,

I took your advice about my battery being on the way out, and replaced it today with an optima red top.

Just for grins, I again tried my predator programmer. It still required that I remove the 3 radio/onstar fuses and three others (tbc/batt (interior lighting), IPC/DIC (dash lights and odometer display etc.) and SEO Ign (accessories)) before it would work.

Brian from tech service at diablosport confirmed that the 2004's draw more current from the battery during the "key on" position and this draws the battery voltage down a bit more, this prevents the predator from procceding with its backup and tune proramming.

An interesting note: when I picked up the optima battery, the service guy at pepboys showed me to the backroom and the graveyard of ac delco batteries he had be getting in of late, he said the problem with the ac delco batteries is in corrosion that builds up on the inside of the side posts, this causes the battery to fail prematurely (he said this results in low voltage and on/off cycling eventually often setting misc engine codes).

thanks,
