751 glow plug timer/relay diagram

[shawn macananny]

Hey gus, I have a 751 with Peugeot motor, 2700 hours or so. It runs great but I've noticed the glow plug timer sometimes isn't coming on. I already have wiring and a push button run into the cab back to the relay area, where do I need to tie it in to make the glow plug relay manual with the button?

I found this diagram on here. It looks like after i test everything, i should cut the wiring at terminal 3 and tie in 12V there right?

Before you cut things up, I'd suggest you open the box up. There is a relay inside it that activates the glow plugs, the terminals do get corrosion on them. It's possible you have the same problem.

How do you get the blue box open? Haha i tried prying from a few difference angles but it kept cracking. The bobcat started in 28F weather without the glow plugs working, so atleast the engine seems healthy.

I can't remember how it came apart now but the one I had was fire damaged, so the plastic opened up some to give me access.
It may crack a bit, but as long as you can get it open, you can glue it back together.
