New Holland Lx 665 starting issue

[jdyoung]

was driving my NH Lx665 Turbo without issue, it started right up, when I finished I parked it on a slight incline and shut it off. I came back a couple hours later and noticed it had rolled back 10 feet or so. I got it to try and start it and it wouldn't turn over, it just gave me a red stop light on the dash. Is there some kind of safety lockout on this machine? I'm not sure what to do from here

Thanks

there I THINK is a safety switch for the seat belt as well as the seat
if either one is not working, it won't allow you to start the machine(unless maybe there is an over ride service mode you can put it in)

your machine rolling forward on a slope, I would think would be due to the parking brake not working, that is if you used it and it still rolled forward on you!
but even without the brake on, with the machine of, it really should NOT roll, due to hydraulics not allowing it to do so!


have you checked your hydraulic fluid level? in both main tank and each gear box!

Yea, seat and seat belt safety switches. Maybe move around in the seat. I had one seat that if you got on a slope and move your weight around the seat switch would loose contact.
When you set in the seat, the entire dash should light up & beep. Then when you hook the seat belt the light for it (bottom right) will go out. If those 2 things are happening, I'd say those switches are working--I'd start checking fuses and relays then. If not, check the switch connections or replace.
This size machine will roll on a hill without the parking brake applied. The LX885 and 985 would not.

 

[mrbb]

OK< I'll ask something else here,a s maybe it was skipped or?/

but have you confirmed that you have a good strong battery and voltage getting to starter,

all grounds good?

as without good voltage things can cause errors and or not allow things to try to start

and what about you alternator? as if it was dying or going bad, it might not have been charging and once a alt goes out, it can cause things to stop die right then and there!

 

[mrbb]

one other things, how much fuel is in your tank, if parked on a slope, if low on fuel, it might have pick up not getting fuel due to angle of tank!

Hey, so I added some hydraulic fluid today and I still had the same issue, I’ll check the fluid in the gear box next

I also get this light when I power it on after the timer counts down

Is it safe to pull this machine to level ground or would towing it make things worse?

 

[Shanmar]

I've done it several times with no apparent affects. I always went slow and not any further than I had to.
Do the dash lights do what I said they should above?

 

[brdgbldr]

That is a low engine oil pressure light. I’m not familiar with that machine so I'm not sure if it comes on before starting the machine or not when it is fully functional. On my Bobcat it only comes on when there is a problem.

If the engine was low on oil, and the incline was enough to expose the oil intake, then when you tried to stat the machine it may have sucked air causing a low engine oil problem.

Try to get the machine level and check the engine oil. Also, look into if you need to clear that code before the machine will start again.

I wouldn't add too much hydraulic fluid until its on level ground, as that;s the only way to get a correct reading
and as for,

YES you should be fine dragging machine to a more level spot, if you have another machine to do so, just make sure parking brake is off,
and with this model, it should allow you to tow it by having someone inside use hand controls in direction you wish to drag it
(I know my lx865 allows this) this will allow wheels to turn and not be locked up!

Does the gear box take the same kind of oil?

I was able to pull it into the garage, it’s on level ground now and the hydraulic fluid looks good, still just getting a click and no engine turning over

The read out says 10.2 for the battery symbol, it’s tough to access the battery to put the tester on it to get a true reading on it, I did try to boost it off my car but nothing changed

 

[mrbb]

if your battery is low, it will not allow things to properly try to start
and the clicking your hearing could be the starter relay

which could happen from low voltage at the starter, or be a bad starter relay!

IF your side covers are like mine on my LX 865,
you can remove then without needing the boom up

and if your battery is in same location as mine(guessing they are being mine is just the model above yours)
you can and should be able to get a battery charger onto battery and try charging battery
and also be able to test voltage at starter!


another possible issue is corrosion on ALL or any connections, from the battery terminals, to battery cables, to power cables to starter and fuse box, and fuses themself


corrosion is common problem on older machines
and it will effect voltage flow, causing again not enough amps/volts to make things work!

and , you mentioned that hydraulic fluid is good, what about actual fuel level
as I said, if things were on a slope, your fuel pick up in tank might NOT have been able to get fuel, due to angle/slope
now your back on level ground, you should be able to get a better reading on fuel level now too!

 

[mrbb]

your model, might be different than mine, so I cannot say for 10% certain

but your hydraulic system should be using 10w30 oil
NOT hydraulic fluid!

but over the yrs, MANY older machines have been filled with hydraulic fluid, due to, either not knowing or not caring,
so cannot tell you whats in yours at this point!

your gear boxes, should be using 80wor likes gear oil
not sure if you have one gear box for both drives or separate one for left/right side(that's how mine is set up, built I know NH changed things based on model and yr of machine)

 

[mrbb]

I did see this off this web site

if it doesn't take you to this info, go to the skid steer section and on page 8 of it!
it has a lot of info on all NH machines! including filter part numbers fluids and amounts and types!

Sorry, I put oil in it not hydraulic fluid

 

[Shanmar]

Yea, 10.2 is too low and will act like what you're seeing. And mrbb's comments about battery, connections, or corrosion all being possible causes is correct. One time, I had to replace what looked like a decent battery cable after I had put in a new battery, cleaned connections, etc.
