I have a 2006 Honda Foreman 500 It shifts fine but does not show neutral when am in neutral. If I pull the brake handle while in gear it well start but that’s the only way. Drive gears show on the display just not “N” any ideas?

Checked neutral switch all wiring connections and the manual says to run an ECU but in order to do this I need my neutral light to come on, hence the problem. Manual I downloaded the wiring schematics are fuzzy and you can not read what it says. Shifts fine into reverse and all 4 gears, but I still get no neutral light and no neutral indication in the dash.

The 2006 foreman 500 no longer uses a separate neutral switch in the engine, only a reverse switch on the rear crankcase - older models had two switches on the rear case.

Neutral is now found in the Lg/R wire on the gear position switch in the engine on both the FM and FE models. You can use a multimeter and see if there is any signal coming from the gear position switch when the quad is in neutral by poking the light green / red wire. If there is no signal you need a new switch or diode, if there is signal then trace it to the J/C4 junction block, all the light green / red wires should be connected together. The 4 junction blocks appear to be behind the front shock under the tank (in front of the coil) by the picture in the manual.

It could also be a blown diode - the foreman uses a 3 way diode in the fusebox.

It is a bit confusing though, the microfiche shows a neutral switch at the back of the engine for the 2006 foreman but the wiring diagram does not, only a reverse switch.

Which model is your foreman? FA, FGA, FE, FPE, FM, or TM?

Its a 2006 TRX500FE I checked the back of the engine and found a small wire going to what looks like the neural switch checked it and was good not sure what you mean by gear position switch. My ATV changes gears with the electric up and down buttons.

Is the neutral light burned out? My '99 Foreman 450S had no neutral light ...... took the circuit board out, and had a new bulb soldered in. An electronic repair shop did it. Works good now.

The switch on the back of the engine is the reverse switch

The gear position switch has 8 wires -- Go section 21 in you manual -- page 21-11

both of the neutral lights do not come on and your can not pull start it. no spark if you put it in gear and pull the front brake lever it well start that way. But that's the only way and its not to cool to start in gear. You can shift to neutral when its running but still no lights.

If you have a meter checkout the Gear position Switch-- what do you mean by both neutral lights, you only have one.

X2 w/Mel....... probably your reverse switch. The manual will take you through troubleshooting it.

The brake lever should allow you to start it in neutral not just in gear - it is a neutral switch/light bypass for emergencies. The ECM needs your neutral light coming from the gear position switch before it will engage the starter or supply spark, the right brake lever has a microswitch that bypasses this and allows the starter and coil to work without the neutral safety.

Chapter 21 page 11 and 12 is Starter relay switch. Troubleshooting the book all wise says to hold down the up and down shift buttons until Neutral light flashes, but every time I try this nothing doesn't help I think that my neutral light well just not come on. I love this machine work it to death but now ITS DRIVING ME NUTS

Bobsundance -- sorry that should have been Section 21 page 21-11

Like HondaTinkerer has said the bike should also start by pulling the right brake when in Neutral & in gear.
Do any other lights on the display light up???

Everything lights up that should just not the Neutral light or "N" on the dash it well not pull start or start when you hold the brake lever in as long as its in Neutral if you shift up or down and get the "1" or "R" on the dash then it well start with the lever pulled

Did you try the one on this forum below?

Key off -- unplug the gear position switch -- using the gear shift tool to do the test. Every wire on the gear position sw. should read zero ohms to frame ground as you shift it with the tool.
