I have a 3 year old 915B that every now and then won't turn over. The hour meter comes on, but other than that, it's like the battery cable is disconnected because the machine is as dead as can be. After the usual ritual of fiddling around with the PTO switch, popping the seat up and looking at the battery, putting the seat back down, looking skywards to see if rain is on the way, getting a fresh beer... and trying a few more times, it will start. But, I know that my luck is going to run out one of these days.
It seems like some kind of electrical issue, as if one of the safety switches might be malfunctioning. Is there a history of specific electrical problems or a trouble shooting procedure that I can focus my troubleshooting efforts on? Is there an easy way to bypass* the safety switches for testing purposes?I don't want to send it to the dealer unless the problem is chronic and they can observe it. On the other hand, I don't want a failure that results in 2-3 weeks of down time while I wait for the dealer to get to it.
I forgot to mention - engaging the PTO will cause something toward the back of the machine to click.
*I'm not one to permanently bypass safety switches, but short of replacing the switches, I don't know of any other way to troubleshoot them.
