'92 Safari horn, doorlocks and speedometer problem. Need help please.

I started having this problem with my Safari yesterday. About a minute after leaving my driveway the horn gives 3 or 4 short beeps on its own. When it does this, the speedometer fluctuates up. Immediatly following the horn acting up, the power door locks attempt to lock (if they are unlocked then they will lock, if they are already locked then they just click as power is applied). This will continue to repeat every few seconds. Yesterday, when it started, I pulled over as soon as it was safe and restarted the engine and had no problem for the next two short trips (3 or 4 miles). Later in the day I left the house with it and everything seemed fine. I got to the local school zone and looked at the speedometer and it showed 80 (I was doing about 20). The speedometer jumped all over the place and about 30 seconds later here comes the beeping. Anyone have an idea where all these systems might merge together and maybe short out. Since it doesnt do it all the time I have no idea where to start looking. I wrote this 4 days ago. Been having problems posting. Anyway, the van hasn't acted up in the last 2 days. Any idea what caused this would be appreciated. Thanx a lot.

Check your voltage regulator output from your alternator. Sounds mighty similar to what my 92 did a few years ago, prior to the whole vehicle going dead.. Replaced the alternator and good to go. I was in the dog house for awhile. It seems the beast only died when my wife was driving it. Sadly I finally gave it up to a drunk driver. Miss that good ol van.
