6. Positive Connection The electronic control system operates on either a 12 VDC or 24 VDC electrical systems The unswitched battery positive connection to the control system is made at the weather proof connector The control system provides switched positive battery protected by solid state MOSFETs These outputs include integral protection against overloads and short circuits An integral 40 AMP slow blow fuse protects the unswitched battery positive circuit Powering the control system through dedicated circuits reduces the possibility of system damage Warning Disconnecting the battery while the engine is running may damage electrical components When using a battery disconnect switch LOFA recommends using a 2 pole switch to disconnect both the battery and alternator output Note A maximum of three ring terminals should be connected to a power stud in order to ensure integrity of the connection The use of more than three terminals can cause the connection to become loose Voltage Drop If control system voltage drops below 6 volts for more than one tenth of a second the control system may reset causing the self test to reactivate Resetting the control system is equivalent to quickly turning the key switch to off and back to run without starting the engine Voltage drops can be caused by a discharged battery transients from external equipment improper wire sizes faulty wiring or nearby lightning strikes 463 3000 08
