Some of you may remember the battery issues I've been having with my GT275. I last posted a month ago, and following up on that thread. Went a purchased a brand new battery. Not that I thought the old battery was that dead, but let's face it, the battery is the cheapest piece to replace.
Saturday I went to mow and it was dead again. I jumped it off and started mowing, but when I got off to pick up some trash, the PTO wouldn't turn back on. So I just parked it in the shed.
Today I bought a new battery, installed it, and mowed the lawn (about an hour). Then I grabbed my meter and started doing some testing.
Stator is putting out a strong 34.4V. Manual says minimum is 34V, so stator seems good.
Battery is brand new. Testing 12.6V after mowing the grass (and let's assume it was not charging while mowing).
I removed the two 15 amp fuses and checked them. They didn't look blown, but I replaced them anyway.
All things point to the voltage regulator. I tried doing a regulated amperage test by measuring the current in the small hot wire going to the battery. I wasn't reading any amperage in that wire, but that may be because I didn't have the tool to put a "load" on the battery like the manual said to.
The unregulated voltage test was inconclusive. It basically is a voltage reading of the battery while the mower is running. The battery was reading in the 12.5# V range at fast idle. It would read 12.6# V when the mower was off.
So does it seem to be the regulator? Any other way I can check? I checked continuity everywhere I could, so it doesn't seem that I've got a short in the system.
Any ideas are appreciated.
