The PO on my truck swapped out the automatic glow plug controller and put in a manual button. Not too long ago, I could bring my 'plugs to life. So I did the cheap thing first and swapped out te button with a starter button I found a Wal-Mart. It had twice the size and seemed pretty heavy duty, so I figured it would replace the cheapo button that was in there when I got the truck. The new button worked great, but then I started getting whiffs of burnt marshmallows. A few weeks later, smoke coming out of the dash. I pulled it out tonite, and it's coming from the button itself. My question is, what should I be using for a button. Obviously a starter button isn't going to cut it. thank you in advance.
