Changing alternator
I'm changing my alternator. Do you have to disconnect batteries when you do this if you are very careful. I know they say to disconnect batteries every time you do any work but that means the truck has to go through its learning process.
Thanks for all the great advice

The alternator 'charge' wire is hot. I guess you could just remove it & secure it making sure it is very well insulated.
When I did mine, I disconnected the batteries. I've done work before on another project where I've removed & insulated hot wires successfully..... Reinstalling them caused fuses to blow & parts to be damaged.
Now, I just dc the battery.

Parts store has a 9v battery on a cigarette lighter plug, or you can rig one if your handy. Just a few bucks and it maintains memory while the battery's are out. Works well on most vehicles but I haven't tried on a SuperDuty.
