Upgrade to a second alternator
The V10 in my service truck took the long slow ride. I located and am in the middle of replacing said engine. My question is, how difficult would it be to install a second alternator in this truck, considering I have it torn down for replacement?
It a 2000 F350 with a V10. I'm looking for more power as I have mounted on the Knaphiede service body a IMT 1015 crane, 3200 lb capacity. I would like to install a power inverter to be able to run an air compressor in the field.
Any help would be appreciated.
Am I looking for a new harness? Etc?

How about just adding a couple of deep cycle marine batteries to the service body to run a bigger inverter, then charge them off the alternator when going down the road? That's what my service body had on it. But I wasn't running a hoist and a compressor both.
Our bucket trucks had generators on them to run the bucket lifts, maybe that's another option?

The factory dual alternator used PCM control to only turn on the alternator under certain conditions, which I don't know what they are. If I was doing what you are doing, I would mount the second alternator but wire it as a stand alone alternator to a bank of deep cycle batteries (two maybe, depends on your amp-hour needs). You can charge them with the second alternator, have a combiner switch that would let you jump-start your truck with the batteries, and not have to worry about factory wiring harnesses and charging strategies. What you don't want to do is to try to run the inverter or the crane motor at high amps from the alternator directly, it needs to be spinning pretty fast to reach peak output, and it can't run at much over 50% of rated output for very long without overheating.
