I have a low hour Mustang 2105 with the 110HP Yanmar engine. Same as the Gehl 7800. Has only 1200 hours.
It is a great machine but since I've purchased it used, it has very annoying intermittent starting issues. I'm not sure if it is electronic or not.
Basically the machine always starts when I fire it up at the beginning of the work day or anytime that machine has been sitting for hours.
Seems once it get warms that it will periodically not start. And the symptoms are very strange. Seems to occur more if I accidentally stall out the machine when aggressively loading the bucket.
So once we've operated it for a bit and then shut it off or occasionally stall it, it sometimes won't start. Basically, if you move the key to the ignition ON position (wait a few seconds) and them move the key to the crank position, about 50% of the time it will not start. It will just crank and crank and crank. Won't even try to fire up whatsoever. However, if I move the key quickly from the OFF position and turn it immediately to the crank position (past ignition ON), it will fire up & then immediately stall out OR stay running. If it stalls immediately, then I simply repeat. Turn the key OFF and then quickly to the crank position. Usually if I repeat this 4-6 times, it will fire up & stay running. Very strange!!
90% of the time I can do this and it will eventually stay running. Then the machine runs great. So once the machine is warm, I typically avoid shutting it down. And I feel the symptoms occur more often if I accidentally stall out the machine.
Occasionally, this trick will not work. So I simply leave the machine to sit for a few hours. Then I jump back into it & it will start fine. I can turn it to the ignition ON position and then crank it right up.
Any ideas what to look for?
