Someone help please

I just replaced my battery, stator and regulator with brand new ones and im still having the same problem.

Battery not charging.

I'm losing my mind.

Lights flicker at low rpm. The bike runs perfect but when i shut it off, the battery will not even turn the bike over. I have a parts bike and switched over the coils, igniter, junction box, rectifier connector, light reserve and i am lost. I checked the harness for short as best i could and didn't find any shorts or corroded wires. (newer harness from a 2006 bike)

1994 VN750
Electrosport Stator
New battery
New R/R

Replacing all the parts you listed and its still acting up makes me think its in the wiring, I know you said you went through the best you could, but a small bad spot can be easily missed. After you get your battery charged again run the bike for about 10-20 miles, once your back home cut the engine off, and try to start it back up. If it starts up that's at least one good sign. If it starts up, then disconnect the battery and let it sit overnight, the next time you ride, after re-connecting the battery, if it starts up fine your charging system is working fine and you need to search better for a short in the harness.

Question

Electrosport Stator - not the greatest

Have you checked output with a voltmeter? Both DC at the batt. and AC from the stator.

Have you tested the R/R?

Could it be a bad starter?

did you check the frame to engine ground? if its loose, it will cause the bike not to charge correctly, also unless you used a TPE Stator, i wouldn't rule it out as a possibility. Lat winter I helped several forum members over a period of three months with symptoms just like yours. The had both Rick's and Electrosport Stators, and both were brand new before they contacted me. they ended up going with TPE stators and haven't had a problem since.

As before (Ceal I think), I can tell you how to easily check for short/parasitic drain if you go that way.

Undo the positive cable from the battery, connect a VOM or test light from the + cable to the + battery post. Key off there should be no voltage or the test light should not light.

Can't rule out a dead starter yet. All we know is, it doesn't restart after being run, we don't know voltages.

Thanks yal. I will check all of these when I get home.

It all started one day when I got caught in the rain.

After the new stator it does a lot better but it's not fixed. Voltage is good until I give it the load test.

Thanks for yals help!

What does that even mean? The only load test I know of is for the Battery, so if thats failing, then you have the problem solved.. get a new battery.
