NOCO IGD140HP Grey 140 Amp High-Performance Battery Isolator

I needed new isolator for my old 1994 dodge van for a 10,000 miles road trip across the USA. It worked perfectly well for me. It was new (not reconditioned) and installation was easy with all hardware provided in the box. They fit exactly in the space that I had when I removed the old one. After my 2-month road trip up it is still working well charging my engine and coach batteries while protecting my engine battery from draining.

hooked this up, does its job, id i needed to id buy some again, full metal design, terminals are perfect, and it charges my batterys amazing.

This product is larger than anticipated making it difficult to mount in a crowded engine compartment. The instructions for a GM Delco alternator system are incomplete making installation almost impossible. NOCO does not answer emails about the incomplete instructions. Battery cables are needed for installation and NOCO will not send their catalog so that cables can be ordered. Forget it if you live in a small town with limited access to cables, etc. Do not buy.

Works fine, but the directions are bad. Had to do some serious studying online to make sure I wired it right to my Delcotron alternator
