I work for a medflight company with aircraft in Haiti. We have multiple J70 Cruisers and are having issues with one of them. The roads here are not favorable and one of our trucks got a battery light after hitting a large pothole. The alternator is putting out 7.7Vdc and 4.4Vac. Originally thought we busted the internals however after putting a new alternator on it did the same thing. Swapped internal regulators with a known good alternator, same result. Put it in a different truck and it works as advertised. I'm admittedly not familiar with these Land Cruisers and would appreciate any help! If this is posted to the wrong place I apologize in advance. Thank you!
