Hey anyone know what a good voltage/amp output for a late Evo stator should be? I've looked around on the ninternet and found a some different numbers.

at the plug on the block, mine is putting out 10V at idle and about 35-45V at about 2K rpm.

I lost a battery the other day and can't figure out why; except my positive terminal connection was a little loose.

I recently put a new voltage regulator on (after my old one started shitting the bed) and the battery went dead a couple of hundred miles after that. thought maybe my stator might be weak.

I know most of ya don't mess with evo's but....


thanks,
Mitch

had the same problems on the way to sturgis on my shovel and had to trailer from KC to Platte.
turned out to be the voltpak but when we checked the stator it was around 60V.

also check to see if the stator is grounded to the case...
if it is you'll need a new one as well.

You want to do a static check to make sure you have continuity(i.e. no resistance) between the two terminals of the stator plug, and then check each individual terminal to the case and make sure you're not grounding(i.e. you want infinite resistance). Other than that, fire the bike up and check DC voltage at your battery terminals. If you're not getting 13.5-14.3 then you know you're not charging.

I did all of that and my readings were normal. but my battery voltage, while idling, was sitting at/around 12.80. sounds too low right?
I don't believe my scoot has a"voltpak?" I bought a new stator but have yet to swap it out becuse it looks like it'll be a bitch to change, I think the front pulley nut is torqued to about 12 million foot pounds with red loc-tite. so I just wanted to make sure before I got comitted.

you have a voltage regulator...
or you'd melt your battery.
its a "finny" box in front of the case most likley.
at idle you'll read lower that operating revs...
run it up to 2500-3000 and check.. you should be 14.0-14.5 at the battery.

no, I know I have a regulator because I already changed it:rolleyes:. But I think my stator is going out ; that's why I wanted to be sure my voltage output from the plug on the block was sufficient.

thanks

I can get the specs from a service manual if you need them (tonight). I went the same shit only to realize I had a bad ground at the voltage regulator. Someone once mentioned that the bare metal area of the reg. is clearcoated which inhibits grounding. Make sure the connection is really good there.

Let me know if you need the specs. Electric can be a real biz-a.
