A-Body - Low Voltage Within Cabin [7v], but will run - 01/27/19 03:29 AM
I am working on a '70 Duster that seems to be winning, it's been sitting for ~15 years for reasons unknown.
While trying to get it running I noticed that I cannot get the ignition switch to trigger the starter relay. If I jump it, it works just fine. I turned the key "on" and jump the relay, engine runs pretty decently.
As I've traced the ignition switch issue, I have the following notes:
We are just trying to get the car to move around the place under it's own power for now. I am not looking to do a full ammeter bypass and such, if I do not have to [for now].
I am nearly out of ideas other than just trying the bulkhead/ammeter bypass and hoping for the best...any other ideas to try?

As I've traced the ignition switch issue, I have the following notes:
- Healthy Charged Battery
- ~7.0v to the yellow starter relay wire when key is in "Start" [should be 12v]
- Pulled the ign switch down, I get 12v at the red wire, but it goes down to 7v when the key is turned on. Seems like somewhere down the line a component cannot manage any current.
- The 7v is also effecting the fuse box as the keyed fuses also are at 7v.
- Pulled apart and cleaned the bulkhead connectors, nothing seemed corroded enough to mention
- Fusible link at the bulkhead has continuity, but I haven't been able to run a voltage drop on it yet. I assume a fusible link will either work...or not. Having low voltage doesn't seem like a fusible link issue to me.
