Called again this morning and Elliot is still out sick! There is a pretty nasty flu going around. I really don't what to talk to him until he's over it! Luckily we are here for another 8 days.

@Chuck My hope is that I never need to use the full capacity of the alternator. My thought is that since the alternator will be working most of the time at less than the old 160 Amp that it's not working near as hard, running cooler and able to handle any extra load that pops up without straining. My main concern is that I like to drive with my lights on all the time. The load of running the lights and charging the batteries can pull some amps. I'm planning to add a shunt between the alternator and the isolator/switch/solnoid (once I decide which way to go) so I can see if the extra amps ever come into play.

Alternator run temperature, or more accurately said an alternator's internal temperatures can be kept in a range conducive to long life with larger frame alternators.  The fact that a certain size alternator is turned up and then run at lower (closer to design spec) will not lower temperatures.

Also, we put additional heat load on alternators because the pusher orientation puts the alternator in dirty, warm air instead of up front and center.  And the alternator's internal fan is working against the direction of air flow.  These are just facts of life with any DP.

Don,t know about jacking up output adding switches and such. I pulled mine (oem) a couple of years ago had IT rebuilt. It worked good for 12 years, and continues to work like it should today. Life's to short to make more problems, but that's just me, every one gets to do what makes em feel good.

Elliot called this morning and said he was in the area delivering a starter motor and would stop by. He showed up and checked out the alternator and admitted that he was wrong about how he set up the alternator. He said he would rebuild it how ever I wanted. Including setting me up with a 28si.

I mentioned that I was thinking of pulling the isolator out and replacing with a switch. He wasn't so sure but after showing him the isolator and how I would wire the switch he really liked that idea. He had been pushing me to go with a solenoid but said the switch would be the way to go. He also gave me his cell number and said if I have any issues call him day or night.

So I've ordered a PERKO switch from Amazon and have moved the alternator cable from the center post on the isolator to the starter post. In effect cutting the isolator completely out of the circuit. Now the alternator only has 2 wires a positive and a negative. Don't get no simpler.

When the switch gets here I'll swap out the isolator for the switch and continue on with life. :)

Ken it sounds like Elliot is a stand up guy. Good to know, seems to be a shortage sometimes.
