INTRODUCTION

 

 

 

 

Congratulations on purchasing the most robust, vibration resistant, battery monitoring device on the 
market. It is designed for easy installation, even with little or no electrical experience 
 
The 

Digital Power Manager w/ Jump Start P/N 40121

 is a weather-proof battery isolator; battery 

combiner and jump start system for your vehicle. It provides Main start-battery charging priority 
protection along with automatically combining two batteries for large electrical loads up to 500 amps 
momentarily: such as winches, auxiliary lights, and other large electrical accessories. The DPM also 
automatically controls when the auxiliary battery will be charged based on the charge level of the Main 
battery. This means the Main battery voltage must reach 12.6 volts before the Auxiliary battery will be 
allowed to charge.  
 
The 

DPM w/Jump Start P/N 40121

 kit only contains the wires and terminals needed to install this kit 

between two 12 volt batteries. The DPM is designed to pass 280 amps of current continuously or 500 
amps momentarily 

during a “Jump Start”.  All wires included in this kit can be seen in the 

Installation 

Schematic

 on page

 of this manual.  

 
This Painless wire harness is manufactured using high quality 600 volt, 275

F, TXL wire. Standard 

automotive wire is GPT, 300 volt, 176

F, with PVC insulation. 

 

Note: Please pay close attention to the torque 
specifications for the threaded posts on the DPM. 
75 INCH/LBS for large posts and 10 INCH/LBS for the 
small post.
