Case 1845C no start issue

[veedub]

I’ve got an 86 1845C it’s been an awesome machine. Anyway I plowed with it two days ago no issues. I went to use it today and it started right up 27 degrees out. I did have it plugged into block heater for maybe 1.5 hours before hand. It ran for maybe 10 seconds at idle and I went to drop the first lap bar and as I did it stalled. I think the lap bar was coincidence not root cause but figured I’d mention it. It didn’t spit or sputter or anything it more stopped like I had shut off the key. I went to start it back up and it will crank but doesn’t even try to start. I haven’t done any trouble shooting yet I have my wife’s car already taken all apart and I need to get that going before I can work on the skid steer. My gut would be fuel shut off solenoid but I haven’t started to investigate that yet just curious is anyone else has any ideas before I go down that path. I did notice that with the key left in the on position I can hear a relay click up in the warning light cluster it clicks about every 4-5 seconds. I don’t know if it normally does this I very rarely just leave the key on it’s either off or I am starting it. I know if I pull out that dash light unit there’s nothing on the backside but a single plug for a wire harness. I have never tried to open it up to service anything inside of it but it doesn’t look super easy to split apart without breaking.

At 27 degrees, and running for a few seconds, I would bet on ice in a fuel line.

i have a 1845c also, good machine but when i bought mine the the gages cluster did not work. its been years since i did this i removed what they had and put all auto meter gages in and rewired that part. in the past year mine started something like that but i don't think its the same problem as if i not started and mid idle it stalls in a few seconds. i betting i have air getting in some were on the full system so it going to be a winter to do list item.

@veedub The most likely cause is the seat switch is stuck in the open position due to ice build up, the seat bar switch may have also stuck in bar down position now, that will kill the fuel like you shut it off, have seen that several times after being used in snow then left outside for a time. bang on the seat with you fist right in the center, and actuate the seat bar several times, it may still not get to come loose. Feel fre to PM me and i can walk you through how to deal with it, I worked for Case and worked on them old girls a lot!

Ice in a fuel line could be possible. As for the seat switch thats a good thought does act like that, but that has been disabled for longer than I have owned it.

if the wire that was used to bypass it got knocked loose some way, or the connection broke it will do that as well, ours has the wires but connected together under the seat. I have also had issues with the lead going to the solenoid breaking off right close to it, ice is way down my list, never had one just straight die from gelling or obstructed fuel lines, they will bog down sand run out of power then die. Trying to remember but check both fuses behind cab on the right side too.

I have had the wire to the fuel shutoff solenoid simply come off on mine. It’s tucked in between the pump and the block. I just squeezed the female end on the wire with pliers and it held tight when I put it back on.
Although this is on a newer 1845c with the Cummins engine.

My 1845C has an in-line fuse in the harness on fuel pump side just above the rear of engine. Looks like it my have been original.

Just wanted to follow up. Wire turned out to be broken about a foot back from the fuel shutoff solenoid. A real pain to work on without being able to get the loader arms up out of the way but I was able to splice it and get it running. I couldn’t find any sign of a seat shut off switch bypassed or otherwise. Maybe this was added later I believe I have year one of production for the 1845c. Anyway thanks for the help guys

glad you found it, had ours break a couple times when cleaning up brush, it is a pain when the loader is down for sure, and I'm not very big
