Thanks in advance for your help! I have a 60 amp alternator in my 1977 Dodge Camper Van and i want to use it to supplement a Solar setup- 160 watt panel flat mounted on roof with a 10 amp PWM solar...

I would dump the diode based isolator, Not only do you suffer the voltage drop of its diodes but they are terribly unreliable. I was warned and mine started killing my batteries on a trip. Then I was stuck on the side of the road, with family, a trailer and in the dark trying to bypass the stupid thing. Never again.
A 100% solenoid type relay will work better, longer and have no voltage drop.
