Hi Everyone, Yes, it's that crazy guy who took out his heater core again. ;) I've got the problems with my cluster figured out (I had left the second ground dangling, piggybacking it fixed everything) but now I have issues with the tach. When I connect the wire I ran from the engine to the dash, I get sparks and the injectors spray for approximately 1 second. If I try to start the van, it won't "kick in". (I only tried starting once.) It looks to me like something is shorting that shouldn't be, but I can't imagine what. Reading through the archives, it looks like I need to connect to pin 1 on the coil. This is the pin I'm connecting to. On mine, the top two pins (one is definitely labeled 1) seem to be the same pin, to the point of a meter showing them as full closed. I assumed they were both the same pin, and connected to the unused pin. I even tried a vampire tap and get the same results. Do I have a bad tach? Everything else in the cluster works, and once I remove the wire I can start just fine. Could a PO have done something weird? When I bought the van, I talked to the mechanic who had rebuilt it 20-30k miles previous. He didn't say he had used any weird parts, although I do need to use the '85 style cap and wires (which he hadn't mentioned). Could he have used a different coil? -Zach
