I just finished my SR swap a few weeks ago and the car has been driving fine. Today I leave my friends house and I notice my turbo timer volt readout is around 10V so I decide to take it home. I pull on my street and the car just dies. I go to start it and it has aboslutly no power.

I hooked up some jumper cables and the car still gets nothing. Wierd thing is that the dimmers and brake lights work, but when the ignition is put to the on position nothing in the car responds to it, cant roll up windows, dash light, fuel pump, or anything. What could be the problem.

ok upon further testing this is what I have found. The fuse box under the dash has abosolutely no power. nor to the terminals for the ignition relays and whatnot. Also I opened the steering column and behind the ignition swith there is absolutely no power on any of the terminals, which would explain why nothing happens when I put the key in the ON position. HELP

okay I was doing some more testing and it seems like the fusable link for the ignition is not getting any power. The fuse is good, but the terminal itself is not getting power. Im going to wait till tomrrow to trace it from the battery and see if I can find anything out. I checked the wiring diagrams and it seems like the ignition has its own line drawn via the plugs on the battery and the taillights and stuff (which work) have their own line. Anyways im thinking a million things right now so I have to wait till tomorrow. any other ideas.

Check your neg battery cable where it attaches to the engine. Also the plugs coming off the positive battery cable, back probe them and see if you have power at the battery clamp end and then again at the connector 3 to 4 inches down on the wires. I suspect these are either blown out or not connected properly. Those 2 wires are also your altenator feed to charge the battery. It sounds as if you lost that connection.

Ya i was up this morning going throught the wiring and I found the problem. You actually called it pretty good. The two connectors comging right off of the positive terminal were pretty coroded. I opened it up, cleaned it, put it back in and shes good as new, cranks harder than it ever did before so I guess its been a on going problem till it finaly gave out.
