new holland lx665

[Ryan]

I just bought a Lx665 and it starts perfect when warm. It counted down 7 seconds this morning but just cranked and puffed out white smoke and would not start. Tried to cycle again and would not start. Another side note is that when I turn key off starter continues to turn for a few seconds. Please help Thanks Ryan

The glow plugs are not working. Use a test light at the bar that goes across to each glow plug. Have someone turn the switch on. If it is counting down you should have power at that bar. A wire connects to the bar at the rear of the head. If you have power then the glow plugs need to be replaced. If not, you may have a bad relay. The relays are located under the engine fuse panel. This is on the left side of the machine, right above the fuel tank in the engine compartment. There are two relays located there. They are under plastic covers. The relay closest to the engine is for the glow plugs.
The other relay is your start relay. The engine continuing to turn over could be caused by this relay sticking. The other possible cause is the relay on the starter itself sticking.

Mike Thanks for the reply. I do have power at that lead wire. I thought I tested them correctly yesterday and put two new ones in. today I pulled them all out and one had the tip burned off it. Can I test them outside the machine. Should I be worried about the piece that broke or burned off in the cylinder. Thanks Ryan

You can apply 12v to the stem of the glow plug while grounding the base and the plugs should heat up. I would think that anything that broke off has already gone through the engine. Even with two new plugs the engine will still be hard to start in cold weather. Glow plugs seem to fail in a cascade. First one fails, then the other three have to heat for longer periods until another fails and so on.

OK Put my finger over 4th cylinder and crank over and there does not feel like there is any compression here. Should I feel some preasure? Ryan

Yeah, you should have compression out that hole.... As far as the starter continuing to crank, I have seen starters do that, but more than likely its the relay hanging up. It should be the big relay right next to the glowplug relay.
