Thanks for the reminder; I did check all that, cleaned the ground and so forth. I've been through starter failure before on this van and it turned out to be the ground, so I was thinking of those things when I did the R & R. I don't think I mentioned it (or more like I found this out after I posted), but I got my headlights back as well after I pulled and replaced the 'B' and 'D' connectors off the back of the fuse panel. I noticed on the 'D' plug that one of the wires had some scorching around the connector. I also have the thing where the turn signals don't work but the indicator bulb in the dash is lit up. It's been in the back of my mind to clean those ground clusters under the dash and localize the headlight grounds so I'm going to go ahead and do that in the case that I have a general ground issue. We'll see how it goes.

Cya, Robert

Robert,

I was starting to go through all this complicated measurement stuff and replacing switches and all when my van wouldn't start. It turned out that the red wire connecting to the starter had a loose connection. Since you just did some work in this area with the transmission, it might be worth looking at . . . Way easier to take a pair of needlenose pliers and tighten that connector than to go replacing switches and taking measurements all over . . . Cheap too! :^)
