I have a 99' Honda fourtrax 300 and I can't get the electric start to work. It's a new battery, new solenoid, and starts with kick start on first try. We have tried jumping it directly off the solenoid itself and can sometimes get a little spark but never starts. Also it's getting power all the way through to the starter itself. Even tried to temporarily bypass (what we believe to be a bad fuse). However there is no neutral light. Would this have something to do with it. Also FYI none of the other handle bar light or brake light work either.

without a neutral light ?, it wont start/fire the plug. FYI, your model does not have a brake light, all it is, is a tail light :).

Alright thanks a lot. I believe I have heard that somewhere. Now it's just a matter of where i can find one.

I belive the lighting circuit is separate to the starting/charging circuit, that may well be another problem, possible fuse, bulbs blown, dirty/corroded plugs.
Electric issues I will confess, aren't my strong point, I have to ask questions myself when I get issues, some clever guys on here though who will be along shortly with some helpful words.

under front fender ( guessing you already checked the neutral switch lower right side of engine ? ), under bars, black box, inside the black box is a diode, if the diode is bad ?, your neutral light won't light up. to test the diode, pull it out, stick a paper clip in its place, see if you get a neutral light ?, if ya do ?, then the diode is bad. DO NOT RUN IT WITHOUT THE DIODE IN THERE !!!.

Well there's no neutral light at all so I we have no checked that.

I've got that logged for future reference! I've not been here long but no neutral light seems to be a fairly common issue with the older machines

lol, a lot of folks don't know about that diode !!..lol.

It takes a while for me to get my head around electrics, once I'm tuned in I start to understand it. As with everything though I guess, it's something that hands on experience works wonders for

Travis: I just ran into a similar situation so I may be able to help, mine was on a 250 so I assume they are pretty much the same. I would suggest doing the following two things.

1. put a multi meter on the positive post on the starter, and ground out the other end of the mutli meter. It should read some sort of positive voltage when you hit the starter. If there is no voltage you have an electrical problem upstream of the starter.

2. Pull the starter out and bench test it (plenty of youtube vids, I would suggest watching one, and it doesn't have to be a ATV, all starters are the same). Very easy to do, there are two screws (12mm I believe) at the back end of the starter. I access them from the other side where the kick starter is. Once these two bolts are removed you can pull the starter. It takes some force to get it out initially, may need to use a wood block with a light tap of the hammer to get it lose. All that is holding it in is an o-ring and some friction once you remove those two 12mm bolts. Finagle the thing out and put it in your vise. Take some jumper cables and hook up the starter to a battery and it should spin like there's no tomorrow, especially since its under no load. If it doesn't spin your have a dead starter. You can either rebuild it, or buy a new one.

Once you verified these two thing I think we will be able to help you further.

even a brand new starter won't crank unless the neutral light is on.

Understood...The multimeter test should confirm it's the light, and bench testing the unit will also confirm that.
