Keeping the amp clamp or ammeter connected to the battery, start isolating individual systems by removing their fuses to shutdown active circuits on the vehicle. If the current reduces when you pull the fuse, you can narrow down …
Set up a BroadcastReceiver for ACTION_BATTERY_CHANGED. An Intent extra will tell you what the charging state is -- see BatteryManager for details. Share. ... @NPike: see the comments on this accepted answer for another question — one can get the current state using the method shown there without subscribing. – Paul Ruane.
returning to the common ground. Individual low-side sensors for the ½-H bridge legs will detect this current, but a summed low-side current sensor will not. If the brake mode must be implemented on the two high-side MOSFETs rather than the two low-side MOSFETs, the low-side current sensor cannot detect the current.
