Battery Isolator location

[bubblerboy64]

I am looking for the battery isolator on my 1987 PT 36. Talking to
Shane about the charging system for the generator battery and he thinks
perhaps the isolator is bad. Gave me some direction as to how to check
it. He suggested it would be in the compartment where the generator fan
is or with the charger. I looked in both locations and can't seem to
identify it. Anyone have intimate knowledge on this one?
