ECU fuse is blowing
I've got an 82 RX7 with Racing Beat exhaust and Holley carb. Recently the Overheat/exhaust system lite came on. Thanks to a forum post the problem was identified as a blown ECU fuse. I replaced the fuse and all was OK for a day then the fuse blew again. The two questions are: Any ideas why the fuse is blowing? Second question: Since I've got a no emissions controls that I know of can the ECU be disconnected? The wiring diagrams have some ignition/tach wires going to the ECU but they may only be inputs only. Thanks!

Good thought. I checked all the emissions wiring and did find one terminal that had it's contact exposed. It measured essentially ground with ignition on but since I haven't figured out it's function it might get power intermittently. I rerouted all wiring to keep it clear and have not had the ecu fuse blow again. The second question remains, however- can the plug to the under dash ecu be disconnected?
