I used to see a lot of Alamo tracts around UCLA back in the day, when he was still based in Hollywood. They were clearly the work of a madman. Sadly, there were signs as early as 1988 that Alamo was physically, if not necessarily sexually, abusing children.
Wow, there's plenty of crazy still to be found at his ministry's website:
Pastor Alamo has been criticizing the government for forty-five years with the truth and they’ve been slinging false accusations for forty-five years. You have to decide who you’re going to believe--this government which has already been proven to be socialistic and communistic, or Pastor Alamo who is teaching you the truth. Either you believe Pastor Alamo or the homosexual Pope.
