upgrading alternator on x749

sparrowhawk · Mar 2, 2011

I was wondering if there are any good options to upgrade the stock 40amp alternator on an x749 to something a little more beefy. An alternative would be wiring in a second battery for auxiallary but I don't know if anyone has done this yet. I'd like to be able to wire up a few added accessories and do not want to max out the current configuration. Any thoughts would be great!

Try looking for a manufacture part number on it. I've found alot of these are automotive alternators and there be more sizes available. A good alternator shop can tell you or internet search will turn up different applications. Sometime a good shop can rework them for more output.

A 40a alternator should power anything you want to add...

What are you trying to add that would cause the need for more power?

Seriously, I'm outfitting with aux. lights as well as a few other gadgets that I will take pictures of once I'm done fabricating. I'm going to pull the model numbers and see if I can find them with Delco or whoever makes the alternator. Thanks all.

Each 50 watt light draws less than 4 amps, your headlights are probably only 35 watts...I just don't see what you could add to tax a 40 amp alternator.

I have 4 50w lights mounted to my ROPS, plus a strobe and various other electrical goodies with only a 20 amp alternator, never a problem yet in 5 years or so.
