Re: 67 Camaro no power to anything
Blast. That would have been nice and simple. I figured the door release may have been wired straight to the battery rather than the fuse block, hence it working when nothing else does. You might need to take a test lamp and start looking for where you have power. Assuming the battery is alright and the positive primary lead is connected to the starter, with the secondary lead connected to the radiator support junction block behind the battery (I've had that one come loose before which caused my '67 to become temporarily inoperable), and the negative is connected to the water pump (or alternate connection to the block), then you want to start tracking backwards. I'd probably make sure you have power at the horn relay (which is the main power distribution point for this car). If not, your problem is somewhere between the battery and that point (essentially, consisting of the secondary lead, the fusible link, the wire along the radiator support, and the horn relay, or just a bad ground somewhere). If you do have power there, check for power at the fuse panel. If you do have power at the horn relay and not at the fuse panel, suspects would include the fusible link, the lead to the firewall harness connector, a problem within the connector, etc. If you narrow down where the fault is, probably easier to identify the specific problem.
By the way, this assumes you have a relatively stock electrical system.
