Smile Hello Folks

I'm fairly new to this VN750 thing, but I'm hooked. I picked up a 1986 VN750 with 6998 miles. Found it in a chicken coop, been sitting there for about 10 years. I gave it quick cleaning, cleaned out the fuel tank, rebuilt the carbs, changed the jets and removed the "ears", removed the battery box to clean the rust and discovered the voltage regulator had been eaten by the acid that had leaked out of the battery. So I got a new reg and harness connector, and relocated the reg to the left front frame rail (plenty of air here). Now I'm wiating for the new battery. I had it running and it sounds and runs very well, but it still does not charge above 12.5 volts. I hope the battery can fix that.

If you aren't seeing over 12.5v @ 4k RPM the stator could be bad. You should see close to 14v @ 4k RPM.

Looks like you got a good start on things, Hope its not the stator as that is a big job, not imposable but big.
Good luck and welcome to the group.

Geeze Louise, there are a lot of those `86s showing up here lately!
Congrats on the find, and welcome to the Vulcan madness.

Is the reg/rec mounted facing the front or to the left side?
How did you attach it?
I have thought about relocating mine to the front, but it seems ok for now mounted by the left rear footpeg.

Just FYI, I believe the engine should not be run without the battery connected.
It could burn out the stator or r/r.

I used one of the L/H air box attach points. The reg is at a 90deg. angle to the radiator.
