Jim, that's the terminals I'm referring to, the wire from my starter to the bulkhead box was damaged,measuring voltage at the battery was 12.8, under ignition load 11.6, at the box inside the car on the ignition terminal it would drop to considerably less, 10.7 and less.
I need a strong ignition/run connection that will continue voltage without as much loss.
I'm changing the starter wire which I believe is 10 gauge, I found an orange wire coming from the passenger block that was cut with nothing attached to it leading to terminal X C on the block,,I have the box separated and just need some advice as to which way to go and what to look for.
Could also use advice on where to purchase new connections, thanks for the help, I appreciate it.
You would have to look around but below is where one can pinch the connector together to then allow it to be removed from the plastic housing.
One could also just cut the connector with a good set of side cutters if the terminal was no longer being used:
While the above pictures are showing the 2971962 connector it is for use with a 14-16 gauge wire. Offered are others that will work with a larger or smaller gauge wire but I don't have those part numbers.
I doubt you may be able to buy just one and they may come in lots of 5 or 10. It depends on the supplier.
Once the new end is crimped onto the wire, the terminal gets pushed into the slot and then the one part of the tab pops out and locks it into the plastic housing. You may look to see if all of the others have the tabs going one way and if they are put the new one in the same fashion.
As far as your voltages, measuring your 12.8 at the battery and then having it drop to 11.6 under ignition load may be fine but now when you measured the voltage at 10.7 or less at the box inside the car on the ignition terminal, did you leave the meter ground where it was on the other two tests like at the battery or did the meter ground also get moved to under the dash for the third measurement ?. If it did, the measurement of 10.7 could be a voltage drop on the power side and/or a voltage drop on the return ground path back to the battery. You need to keep the ground at the battery for a reference point. Moving it around can have you thinking it's a power delivery issue but it may be that by itself but could also be an issue due to poor grounds.
