First off- This is a new to me project, and appreciate all the help on this site.

Couple things electrical.

When turn key on and start it- the RED oil light is on always, drained oil, cleaned filter, new oil and its full.

R/N Lights- reverse and neutral I assume.

They never come on, I can move shifter and it goes in gear like it should but no lights.

Any advice- also has brand new battery..

Thanks Again…

The “red” light should be oil pressure….. Please refresh me, the 335 has the external oil tank reservoir (like the 500) correct? My quick thoughts….. 1) If so (has oil tank) try bleed the air (clamp the upper “vent” hose for 10-20 seconds and release, hear air?) like that of the 500 oil change procedure. 2) Pull the valve cover (when your adjusting your valve lash clearance from other thread/posts) is there fresh looking oil up top? Start it briefly (with cover off) to see if your getting any oil flow up top. 3) Bad sensor, replace. 4) Bad pump, replace.

As for the “green” light…. Yes, should be neutral indicator. If not working, could be dash bulb, break in the wiring or a bad switch on the transmission. Only way to check is to get out the electrical test meter and start probing for a signal.

Good Luck!

Thanks alot of good info..

The oil tank is a metal one under front fender and it has an oil cooler (no radiator).

I drained, pulled filter in rear of it and put in new oil.

I will do exactly what you say and try it- Thanks

I will also try to check as you indicated, I did see wires going into the shifter- that is where I thought the switch would be.

But first will see if I have 12v at bulb and check bulbs..

Yup, I’d start at the bulb and work my way back to the switch.

Another thought on the oil…. check the tank outlet to motor fitting. There is a screen on it that can become plugged (rarely, but it can). Pull the hose from the right side wheel well and in-thread fitting. Clean out with brake / carb cleaner. Note, you’ll loose your fresh oil…. but it may be worth a look!!

Good Luck!

Well I had a 12 lighted switch and has a tiny bulb in it. Took all apart and soldered into Polaris fixture, works perfect.

The bulbs are silicone in so not to vibrate, so added some to new bulb.

So now onto my oil hot light. There is no sensor it comes on when fan comes on, however It is lit all the time. I got a good used LR60 and now the thermistor workd and fan only on when hot, just got to fix bulb so stays off till hot, thinking it’s a ground thing.

Thanks for the help

LOL…OK, I guess you CAN change the bulbs IF you have the know-how to do it. Good fix!

I hadn’t even noticed that your machine is oil cooled. The thermistor is the “sensor” I was talking about.

Let us know how everything goes.
