Hi Folks,
Have not yet installed knife isolation switches. However, did put in JEGS jumper terminals and have used several times to make jumping easier from another vehicle. Don’t need to pop up the engine cover. Then purchased a NOCO GB40 … works OK on the FORD E450 10 cyl. when both house and chassis battery dead. Have been putting off the engine battery change-out till a few weeks from now.

Unhooked the air hoses and ran a couple of short battery connections to the jumpers without disconnecting the battery. Not an answer for everyone ... but helps us.
