'83 Interstate neutral switch

Postby nome » Fri Jul 01, 2016 12:32 pm



I have an '83 1100 Interstate that I've rebuilt. It's running great but the neutral light does not work correctly; only comes on, sometimes intermittently, while in 5th gear.
Does anyone have experience/advice regarding accessing/replacing the neutral light switch?
Thanx!!!

my 83 aspencade's neutral light used to come on only when i was changing gears and the clutch lever pulled in. you have 2 choices.......1, you can pull the motor off the bike and remove the front engine cover and replace the switch thats on the inside of the front cover if its the same as the aspencade or 2, you can do what i did, remove the switch diode which is located on the main wire harness thats located under the air filter box. i hooked up a 2 inch "jumper wire" with male blade connector ends and it went from one side of the diode connector to the other side of the diode connector.

getting to it is a pain. you have to remove the tank shelter, remove the gas cap and the tray thats under it, unplug the hoses that go to the cap tray, remove the air filter and the filter box. once you have the filter box off should be able to see the diode. it runs along the main wire harness on the inside of the frame rail,(you might have to pull up on the wires to get at it) and it looks like this..............http://www.ebay.com/itm/Genuine-Honda-3 ... Sw8lBTn0mw once you use a jumper wire, you'll be able to fire it up in neutral or any other gear without holding in the clutch lever. make sure you have it in neutral before you press your starter button. your shifter light and gear light should work normally once the jumper wire or a new diode is put in.

here is what your neutral safety switch looks like..........http://www.ebay.com/itm/Honda-NOS-neutr ... Tb&vxp=mtr

Did you by any chance have the front cover off...like to replace the water pump? Thinking the switch may have not been aligned when the cover was put back on.. (you don't have to pull the engine to get inside the front cover to get to the switch)

I think the 82 switch is different from the 83....and if the Aspy has indicators for all the gears, it would be different than the Interstate

the 83 aspy has a gear indicator,(upper right side of LCD) as well as a neutral light,(left side of LCD). he says he has an 83 interstate. im not sure if they are the same, but the engine cover on the 83 aspy has to come off to get to the switch thats why i never changed mine.

somewhere in here wingadmin posted a photo of the switch inside the front engine cover.

you stated that .................

"only comes on, sometimes intermittently, while in 5th gear"

for the 83 (and 82 ?) Honda changed the red warning light (located in the tach) for low air pressure in the rear suspension to purple and it is now a "OD" indicator light (ie: 5th gear).

so .................. my question to you ............ Does the the OD light come on in 5th gear ??? neutral ??? not at all ???

if the front cover was off (for water pump change) it is possible that the neutral / Over Drive switch did not engage properly or is 180 out.

Wow, thanks for the information everyone!

I do think the Interstate is different from the Aspencade; mine does not show every gear.
Also, no, the OD light has never worked and I miss that from my old (wrecked) '83. When I got this bike 3 years ago, it had sat for at least ten years and I do not know the history so don't know if the front cover was ever off.

My manual isn't real clear on the neutral switch location, but if I understand these posts, it's behind the front cover, correct? Same location as the OD switch?

Thanks again!!

The neutral switch and the OD switch are the same part.Under the front cover.It can be removed without pulling the engine.
I would locate the plug and test from there first.

Here it is - the inside of the front cover. This is an 82, with neutral only (no other gear position sensors):

Thanks again and sorry for the delayed response; my internet was down for 2 weeks.

The picture and diagram are great!!!! This project may wait until winter or I have to replace the water pump. I can't see opening up the front cover just to check/replace this switch, though I do miss actually seeing when I'm in neutral / 5th gear :-)

if you can take your false tank cover and the air filter box off, as you look at the wiring running down the left inner side of the frame you should see one of these..........http://www.ebay.com/itm/NEW-RECTIFIER-f ... hn&vxp=mtr its a diode that is suppose to let you know when your in neutral so the green neutral light comes on. mine went bad so what i did was connect a "jumper wire". take a short piece of wire and crimp 2 male connectors to it and plug it in where the diode goes. if im correct your neutral light should come on when your in neutral. if it doesn't, remove the "jumper wire", put your diode back in and order a new one. the OEM part number of the diode is....31700-124-008
