Recently, my 1993 bandit 200+ has started shutting down after running under a load for 15-20 minutes. The engine just shuts off at full rpm while I'm chipping. No sputtering like it's not getting fuel or spark. Just like someone walked over and shut off the key.
My local mechanic replaced the alternator with a smaller one as he said the old one was overcharging the battery and causing the amp guage to trip and shut it down. (During start up of the machine, you have to hold a battery voltage button in while turning the key and then release the button after it has started).
He tested the new alternator while idling for 1/2 hour and all was fine but he didn't test it under load (no way to). We ran it again and the same thing happened - shut down after 15-20 minutes.
Any have any ideas on what's going on here and what to do to correct the problem?
Motor is an 80hp cummins diesel. Chipper is 1993 200+. Battery is an 850cca farm industrial battery for diesel engines.
Thanks.
