Finding battery draw with thermal camera
Well I figured I would post these pictures , it works. I read a while back about thermal cameras and ended up buying a flir e5 thermal camera probly year or so ago. We mostly have used it for bearings on drive lines and engines. I remembered reading some one using it for battery draws. I actually have used it twice in a couple weeks for draws. The first one ended up being a alternator which was pretty quick find. I usually make sure the vehicle has sat over night so its cold [relatively same temp in/out front to back] and give a quick look with camera. The alternator stuck right out. Know yesterday I had a 08 dodge 5500 that has a dump deck and is highly modified for oil field. 90 ma to 100 ma draw. So this morning decided to get camera out and within about 5 minutes had my draw [auto shut down for engine over rev limiter]. Here is the pictures from under the dash with thermal camera and iphone. Unplugged module and we went from 95 ma to 20 ma. [Thermal camera] [Thermal image] . I would not suggest go out and say buy one because its going to be the go to tool because I must admit we have only used it a handful of times. This is the one time I could say it defiantly helped.
