All Things Chev

[MudRunnerTD]

Hi Mark,

I had a read back trying to figure out if the dual Alternator was a Chev thing or not? trying to figure your need. It appears your just looking for it for supporting the winch is that right? as the Chev Alternator is supplying enough for your engine?

This is a No Brainer, especially as you have a tray back. I would be 24v-ing the hell out of that! You have plenty of room to store 2 batteries under the rear tray for your 24v setup, your committed to a second alternator so 24v all the way. Your fridge will take 24v as will your LED Light bars if you want it.

Your Winch will just love it. its a whole other level. I can't agree with Winnie about battery life though to be honest, a good 24v system will last as long as any 12v system and there should be Zero detriment to the storage batteries in this scenario. Im not aware of any Race cars that are swapping out their batteries after a couple of events unless they have cooked them or the Rich guys at the pointy end just because new is good. Buy a pair of New batteries for your 24v system though and make sure they are the same. make sure you fit an isolation switch with at least 600 continuous Amp rating and you should mount that in the cab within reach of the driver. I have a mate that runs cheapish Bond batteries under his tray running 24v and has competed in 2 Outback and 4 Cliffhangers at least. Plus heaps of club stuff in between.

Note also your Winch Motor Ishka is not like a normal 12v motor and has the capacity to take ALOT of power unlike the Warn motors. They have a completely different winding system and are designed for a static industrial application. Given this they don't tend to burn out the windings like a 6hp Warn. Tough. The Ishka motor was an accident. a guy a few years ago had a Pallet of them sitting around and he couldn't move them. He noticed that they had the same spline as the Warn 6hp so listed them for $130 each on a Comp page with no promises "Good for spares. Guys bought 3 or 4 each. I was strapped and did not buy any damn it!! Well bugger me if they are not Bloody Awesome and are rated far better than a Warn and hold their own in the Comp Trucks. Unfortunately when the Dump supply was gone the restock was way more expensive but still cheaper than Warn. Will be my next motor for sure.

Only advice i can give for running 24v through your 12v motors is Avoid Reverse Winching (Winch Out) as this will kill the motors quickly, especially the Warn. You have an Air Freespool for that reason so happy days.

24v ALL DAY
