wow.. it is tight!with the "trailblazer" just call it a Colorado 7, the trailblazer sold in other countries was marketed here in Australia as the Colorado 7 holden just added the trailblazer decal in australia to try and spruce up the Colorado 7( just a sales thing ).
when looking for addons for the trailblazer just look for Colorado 7, when it comes to the engine bay and front end the ute and 7 are the same.
piranha make a tray that will fit the ute and 7, it involves moving the computer over a bit and installing a tray.
it is really easy to do and wouldn't take more than about an hour to fit.
it is a very tight fit and its pretty much made to have an optima d34 yellowtop battery.
I use a redarc bcdc charger to charge mine.
the redarc can be setup to also take solar input so when the vehicle is not running the battery can charge off solar panels.
this setup runs my waeco cfx65 without a problem when parked up for the day using a waeco 120w solar kit to keep it topped up for the night.
if you do use a batterybox inside the vehicle make sure it is vented to the outside of the vehicle or use a battery that does not produce hydrogen gas while it is charging
here are some pics of mine
Hey mate,you could probably swap out the main battery with a smaller one but you would want to make sure you get the same cca/ah you would also need to make a custom battery tray for the second battery or modify the piranha one.
I am not sure how you would go with warranty repairs if you use the wrong main/starter battery and have electrical/starting issues.
but you could still do it imo
I posted pics about it on another forumHey mate,
Those pics look great. I also have a querstion about the breathers. Where the hell are they??? I have a had a bit of a look around underneath and really struggle to find their locations. Do you have any links to instructions or guides as to where they are located?
Awesome thanks for that! I'll have to start looking, might need ramps first though.I posted pics about it on another forum
