I be using an 85 Amp IR alternator with this design. Couple of questions.
<![if !supportLists]>1. <![endif]>For the primary alt, is it ok to go with an 80 Amp Shunt and ANL? I understand they will take 1xx % of rating?
<![if !supportLists]>2. <![endif]>For the secondary alt is it ok to replace the fuse-link in the design for an ANL? Rating 10 amp?
<![if !supportLists]>3. <![endif]>The B & C schematic is slightly different in breaker/wire sizing. Should I adhere to that more closely than Bob’s?
<![if !supportLists]>4. <![endif]>If I understand the instruction the SD-8 indicates the warning light is ON when the switch is off or the OVP has tripped. I’m not sure if I want that big yellow bulb on all the time? What other warning light configurations are folks using?
<![if !supportLists]>5. <![endif]>My ANLs/contactors will be on the firewall. Are there any caveats for protecting them from heat, dirt, oil, water etc?
Thanks,
Glenn

The shunt is the same size as alternator rating. You
can use an ANL as low as 35A with a 60A alternator.

Sure. Not an ANL but an 20A ATC fuse in an in-line holder.

His schematic works as advertised. So does mine.

Don't install it. I presume you have a low voltage warning
that is independent of the alternator(s).

Cessna, Piper and Beech don't worry about it.

It must not be a big deal.
