VAF brain trust
I've have an occasional erratic oil temp jumps of 30-50 degrees and right back down. After the initial "hmm" moment the first time followed by a precautionary landing, I narrowed it down to probe, or I think ground. It seems to come and go randomly, sometimes in climb, others in descent and even straight and level with cool air into the cowl with no real correlation to phases of flight.
After a little more thought and research, I think it may be ground or alternator. I went up with a flying buddy so I could test and he could fly. I wanted to test if taking the alternator offline would make a difference.
After getting up to normal op temp, we set up for decent climb rate to maximize load on the engine and to try and get the warning and then I took the alt offline- as soon as I did, the erratic behavior stopped and temp was steady.
I am going to start the conditional in the next week or so, and will check the ground and may add a second. Any thing I should look at on the alternator or other thoughts?
