I'm in the process of ordering a new diesel
and the question has come up on whether or not to have it electrically isolated. This is the first time I've ever run across said concept
and need some guidance. Could someone a) explain the concept
to me and B) list the pros and cons of the concept?
I've been looking at the electrical
drawing the dealer supplied and can't make out head
or tails. Partly because it shows + and - leads but no battery
. A little clarification would be nice. How does it all work? About all I can figure out so far is that the negative battery
lead goes via a solenoid switch to the engine
and is only connected to the engine
during start up. Once the engine is running, the negative is cut.
