SXR Battery draw

[Mike W]

Apparently I have a slight draw on the battery. Let it sit a few days and the battery (new) was dead. Replaced it with another known good battery and the same thing. Any common things to check?

Also, is there some way of checking if there is a draw on the battery?

Regulator/Rectifier probably has a bad Diode that is allowing the Battery Charge to back flow and drain.

There are some Resistance Tests you can Perform. See Kawi Manual for Test. If bad, Replace the Regulator/Rectifier.

If that doesn't fix it, then the CDI is bad.

Luckily I have a new regulator I can swap out. The ski came with a cheap eBay Venom CDI so Chances are that is the one that is bad.

Thanks for the quick response.

Disconnect battery and put simple ammeter inline with the cable (positive). Should read it pretty definitively. Diagnosing where it is going can happen the same way by putting meter inline with all components one by one.

I use a multi meter and set it in Mulli Amp scale. Disconnect one battery lead and connect meter to that battery post and battery cable you disconnected…. Read your draw…. If you see a number like .00 or .000 the meter may have a blown fuse… fluke meters are protected by a expensive 10 amp fuse….if the meter can’t read then this test won’t work…

You’ll prolly see a number above .015 or 15ma,
Like 125 1/8 amp or 250 1/4 amp or more….

You’ll have to prepare the ski for isolation testing after you’ve measured your draw… disconnect power and the meter and gain access to your electrics…. With electronics open and accessible, carefully and safely hook your meter again and measure your draw…. Now disconnect an item to test if it’s the draw, like JC ^^ said, rectifier, if draw is still there, then do CDI like you said, then bilged pump and so on… good Luck
