My glow plugs stopped working so I bought a part from the local dealer but when I removed the cover in the upper right (from behind) engine compartment and touched across the posts the engine started turning over. Is this NOT the glow plug relay? The part they sold me looks just like the one that makes the engine spin. Are they combined into one unit or am I in the wrong place on my machine? Help!

On my 743 bobcat it has two soliniods both look the same one for the starter and one for the glow plugs trace the wire from the glow plugs and you will find it.......it could be the same one I can't see it from here do you turn the key one way to heat and the other way to start? If not I would look for a bad connection on the glow plugs from it or a bad glow plug if one dies the rest might not work
Right place, just need to look a littler closer for the second relay that is thereOn my 743 bobcat it has two soliniods both look the same one for the starter and one for the glow plugs trace the wire from the glow plugs and you will find it.......it could be the same one I can't see it from here do you turn the key one way to heat and the other way to start?

If this switch is working should you be able to hear it click when you push the glow plug button?Right place, just need to look a littler closer for the second relay that is there
New Holland has a button that you push and hold. It clicks or clunks and then usually I hear a high pitched whine that goes away when the glow plugs are hot, usually about 10-15 seconds. It stopped doing that so I figured that the relay was deadOn my 743 bobcat it has two soliniods both look the same one for the starter and one for the glow plugs trace the wire from the glow plugs and you will find it.......it could be the same one I can't see it from here do you turn the key one way to heat and the other way to start?

Stoped clicking or wineing or both? Check for power could be a fuse or switchI have the same machine and am having trouble starting it. I know the sound you are talking about
I hear a slight click but no clunk and no whine. It will start if I plug it in for an hour or so like in the winter.Stoped clicking or wineing or both? Check for power could be a fuse or switch

The glow plugs are in circuit with the coolant temp switch. If the switch is bad it cqn cause the glow plugs not to turn on because it thinks the engine temp is warm enough. Try unplugging both of them then turn the key on. If light comes on more than likely it is your temp switch. New holland mechanic 10+ years This may sound dumb but check fuses insid3 cab on right upper and on the engine wall under black boxThose glow plugs do go bad. Have you ever checked if you had voltage at the glow plugs when the button is pushed?
