Could Use Some Electrical Help...

So for as long as I've owned my Honda 300 it's given me problems starting. All my mods are in my sig, so you can see what I have...

IF it's left outside overnite and temps are around freezing or very chilly the quad will barely turn over. I need to kick it. Fires up 1st kick.

IF it's left for days or weeks without starting in a heated garage, it's a crap shoot if it will fire up or if I need to kick it.. bur way better than if it was left out overnite. Always first kick it's running.

IF I have to kick it because the battery won't fire it up, & I run the quad for a little bit or hours, it will always fire right up with the battery.

I had installed a new battery over a year ago thinking it was the culprit, however it continued to do the same thing.

I do have the winch wired up to the aux pink wires direct. it's not with key power.



I'm leaning towards the rectifier?? I remember a while back I tried to check the voltage while cranking & was getting something like 7v, but while running it was 13v or 14v if memory serves me correct...


I would love some advice so I can check some things before I just start throwing $$ at it replacing parts!!!!!

Thanks in advance!

Is it slow to turn over? All my 300s I’ve had start great but once I put the 380 on it they start slowly. They say the starter reduction gears help, I think it’s the 250 big red gears but I’m not sure

Had to talk to a friend about it, this is what he found for me.
