Hey All,

The charging system for all trailblazers is a little problematic. I'm sure you guys have all noticed your headlights dimming at night when the A/C comes on or when you turn the radio up. In February we made a set of upgraded cables for our own TBSS and it made a very nice difference in the brightness in the headlights and also reduced the dip I see when my efans come on or my A/C turns on.

This isn't a cure all but it will definitely help your charging system. We basically run a new 4 ga wire from the alternator directly to the battery. We also upgrade the ground to the battery and better ground the block.

Heres a link to them on our webpage

We should be releasing a kit for the I6's soon.
