On my 1083, replaced the alternator and regulator app 50hrs back, been running 100%. Started up this weekend and voltmeter was 25v and would raise with rpm, whereas before it would be 28-30v continuously, idle or higher rpm. Got the TMM troubleshooter for alternator, all fingers point to regulator but not 100% sure with what I'm seeing.
After starting app 1min, it would go from flashing green on both top flash amber on one then both, then intermittedly go back to green(engine loads up), then back to amber and stay there. Amp output increases with engine rpm(very low output at idle). Armature is magnetized while flashing amber. Jumped 28v to E term on regulator with no changes.
No noticeable voltage drop from batteries to alternator.
What I did find on intial troubleshoot was jumper between two start batteries was loose to be able to move it freely, but not enough to break the contact. My thought on this that if the start battery was disconnected while charging, was that at worst the alternator would have blown diodes, but on the test that seems fine.
So im thinking its the regulator and why would it fail within 50hrs of use. Thxs
