Please tell me it isn't the stator

Hi All,

So, my good old 89 750 left me stranded twice in 3 days, in events that may be unrelated but I'll let you pros be the judge of that.

Saturday morning, I drove over a bump, and the bike died. No power. Got it home and it turns out the ground wire snapped between the battery and the frame. Went to the auto store to get new wire. Didn't have 6 gauge, so I made 2 wires out of 8 gauge to replace the old one. Fired right up, no issues. Rode it all around this weekend (~200 miles). Then today (monday) I started to have some issues getting the bike to fire up. It was contrary once, but fired up, and drove it about 15 miles. Later in the evening it just didn't want to start. Finally got it started and headed for home, about 50 miles away. Took a lot of back roads and had the high beams on the whole time. About 10 miles from home she just died on me. The headlights were really dim right before she died. I tried to start it back up, and the starter wouldn't do anything, but I could tell it was drawing power. I tried my damnedest to push start it, but every time it would sputter and die on me.

Obviously, the battery is drained. It it possible that the wire I used to replace the broken ground could have caused this charging issue, or am I just unlucky enough to have the stator go out 2 days later? I can do some electrical tests tomorrow once I pick the bike up, but I thought I'd get some advice on what my next step should be, and how dire this seems to y'all.

Thanks!

I mean sure. it could be the stator but that would be a colossal coincidence that you broke a ground and the stator went bad too. A bad ground can certainly cause everything you mentioned. If the ground wire snapped then you might have other brittle wiring that is corroded and causing problems. I would clean the ignition switch as well since it's free and a source of strange happenings too.

As stated, check the simple stuff first. Otherwise grab a multimeter and test the stator and r/r.

So, I charged the battery up enough to get it running. Voltage was around 12.5 when off. Cranked it up to 3000 RPM and the voltage only went up about 0.03v so the stator isn't charging the battery. After letting it run for a,few minutes the battery voltage dropped down to 11 something.

I got to thinking: When I replaced the ground wire between the battery and frame 2 days ago, there was a yellow with black stripe wire that was bundled into the connector to the frame. At first glance this looks like a stator wire. Is it? Should this wire be grounded to the frame? Maybe when i repaired the ground connection I also hooked this wire up when it shouldn't be? I've only had this bike for a year so I don't know what all could have been done to it by the previous owner

On second glance, this wire is black with a yellow stripe. My mistake

I suggest testing the stator and rr directly before doing anything else.

slim also has some awesome guides. I think he can PM them to you if needed, not sure if theyre publicly posted anymore?

most of the ground wires on the vn750 are black/yellow

Did the stator tests. The voltage between each segment was about 8VAC, not the 40-70VAC everyone suggested. So, stator it is!
