How to make your light switch work again

[jachady 130]

Someone was looking for a good light switch for their tractor. I had a good one for a spare, but I made it "good". When I took it out of the tractor it didn't work. Here's how to fix you own switch.

So here's what you start with.

Remove the chrome (or used to be chrome) surround. It just clips into place.

Then carefully pry these tabs back. You need to pull all four of them back.

The switch should come apart.

Clean everything. You'll be surprised how much stuff is in the switch. Dont' forget to clean the contact points.

You will also want to pull out the black pointer and clean it really good. I have found that it sticks, not fully seating the contacts.

Don't lose the little spring.

Then carefully put it back together.

The hard part is getting the tabs back on tight without craking the black housing. Just be gentle.

Good luck.

Lookin' good Jachady.

I'm glad folks are finally applauding efforts like this instead of just screaming "NO USER SERVICEABLE PARTS INSIDE, JUST BUY ANOTHER ONE !"

Glad we are winning over converts. You efforts here help to promote that and should be applauded.

:D

Not that you want to do that again, (I don't know how many times you can pry back those tabs) but next time, pack the inside with silicon dielectric grease. It keeps the moisture out and prevents corrosion.

As a matter of fact all electrical connections should be packed with silicon dielectric grease (after they are cleaned). This once of prevention is worth many hundreds of pounds of cure !

It works well inside both ends of the high voltage coil wire also and on your battery terminals !
