2.Switch off all devices operating from the battery, or open the battery switch (if present) to disconnect the battery.
3.Wait 10 minutes for any explosive battery gases to dissipate.
4.Remove the nut that connects existing wiring ring terminals to the battery negative terminal stud.
5.Move or reorient the existing wiring ring terminals on the battery negative terminal stud, so there is a flat surface on which to seat the BTS mounting plate.
You may need to bend the ring terminal crimp and/or wires slightly downward to allow the sensor to seat flush to the top surface of the upper ring terminal.
6.Mount the sensor directly on top of the ring terminal, as shown in Figure 11, and firmly tighten the terminal nut.
FIRE HAZARD
In this procedure, you must install the DC wire on the battery terminal, then install the sensor on top of the DC wire. This sequence is required to provide the best connection to the battery and to ensure correct performance of the sensor.
Failure to follow these instructions can result in death or serious injury.
7.Check to ensure that the sensor and all wires are held firmly and cannot be moved.
