difference between battery isolator and battery relay
On ebay you can find battery isolators and battery relay isolators. What is the difference?
from what I see.. the isolator still creates a draw on the batteries but not with the relay?
I currently have
63a alternator - new (factory 1978 chevy)
90a battery isolator
2x duralast gold 1000ca batteries in parallel on A of isolator
2 x 1300ca dump truck batteries in parallel on B of isolator
I am going to upgrade my alternator to a pontiac transport 140a and will need a new isolator/relay
