Polaris 550 EPS Sortsman 2012 charging issue

[Dave2012]

Hey guys, new to the page from Australia. Just wanna know if  anyone has had an alternator charging prob if using an auxillary piece of equipment eg spray unit. New battery, and cant seem to catch the alternator playing up, reads all good on outlet power.Just doesn't keep up the charge only when using spary unit, and headlights are off.....

How is the sprayer wired ? Directly to the battery with a switch/relay ? Or into the fuse box or harness ? 

Also what’s the amperage draw on the sprayer ?  There should be an electrical label on the unit someplace that shows the electrical draw on the bike when in use.

so its just running the battery dry and the pod doesnt show a low voltage sign or check engine light or anything?

You really need to find out how many amps the sprayer is drawing and compare it to what your machine is putting out. . I had an issue with a high power radio drawing too much, so I purchased some 12 volt 5 AH Lithium Ploymer batteries used for large Quad copters. I wired two in parallel put them in a water proof box with a 12volt utility outlet and it makes a nice rechargeable portable power pack.

I run a Shurflo spray pump (7amp max draw) all afternoon on my 06 Polaris 500EFI when spraying weeds.  It is an on demand pump that starts and stops with pressure.  I start the ATV every 20 minutes or so to move it in a new area to spray and it has not failed me yet. 

I did have a charge problem that never showed on the instrument cluster.  No low voltage or low charge warning.  Turned out it was a bad alternator and wire harness.  I replaced the battery with an AGM and have been very happy since.
