Mick's GU Patrol Ute: Canopy Power System and Under-Bonnet Rebuild

A fully fitted canopy power system with 225Ah of slimline lithium, then an under-bonnet rebuild that turned up a faulty VSR and a failing alternator.

Mick was referred to us by ABR Fabrications, a quality tray and canopy builder here in Townsville. We've done plenty of projects together, but this turned out to be one of our biggest and best builds to date.

A canopy with all the fruit

The job started as a canopy fit-out. Mick wasn't local, so we had time to finish everything before delivery day. The canopy runs on 225Ah of lithium, tucked neatly away using a Power Lithium slimline battery. Because the canopy is enclosed and out of the weather, we paired it with a REDARC Core 40 DC-DC charger. The fridge, strip lighting, water pump and Travel Buddy oven all run from the canopy control box.

What we found under the bonnet

As with most older vehicles, once the Patrol arrived we found years of different owners' attempts at 12V accessories under the bonnet, and we couldn't leave it like that.

We found a heap of unfused connections. The auxiliary battery was flat and not charging because of a faulty VSR, and once we started the clean-up we also found the alternator was on its way out.

Back to our standard

We rewired and fused everything properly and got the Patrol back to our standard. Mick has given us nothing but glowing feedback since. He even drove 1000km back a few months later to have more accessories fitted.
