How to Wire Up a Sure Power 120 Amp Two Battery Isolator
Question:
how do I wire it up to a 2002 Chevy Express Van so I can use the second battery to run my audio
asked by: Jack
Expert Reply:
Battery isolator # DW08771 will have connection posts for each battery and for an alternator. The main battery will connect to position one and the alternator to the A post. The second battery will attach to the 2 via a circuit breaker that is rated appropriately for the battery. Output from the second battery positive post will then go to the items you want to power. I have included a picture that should help.
If you do not have a group 1 alternator then the E post will not be used. The alternator needs to have a max output of 120 amps to use this isolator.
