2013 LFX starter issues

I have a 2013 LFX and a 6L50 in my 66 Chevelle and Iím having a weird issue with the starter. Any advise would be appreciated.

When I turn the key to start, sometimes the engine will start right up. But most times the starter just clicks. Like weak battery. I keep trying to start it and after 2-30 or 40 times, I never know how many, it fires up. So Iíd consider it intermittent but it happens way more often than not.

The battery is solid. Iíve replaced the starter. Iíve ohmed all of the wires in the circuit and itís all good. From the key switch through the fuse block/firewall connector to the connection on the starter solenoid.

Today I pulled the wire from the solenoid and put my voltmeter on it. Every time I turned the key to start I got 12 volts. Every time.

So I put my probe in through the back of the connector so I could check the voltage with the wire plugged into the solenoid. So with the wire plugged in I get 6 volts when trying to start and it clicked. When it finally started (after 6 clicks) its because it jumped to 9 volts.

So to recap, unconnected I get 12 volts every time. But when the wire is plugged in to the solenoid it get intermittent 6-9 volts, 6 more often than 9.

Thoughts?

Ground issue? Is it easy enough to reroute the ground to somewhere else to test?

Either a ground issue or a issue with the power feed to the solenoid. Probably the latter. It's failing under load and checking the resistance won't show the issue. The amount of current required to ohm the wire is very small but the solenoid takes more and it can't carry the load. I would start with the relay if you have one feeding the solenoid.

Thanks for the input. I have two braided ground straps that go from the heads to the firewall. I have one other that goes to the frame. I also have a ground cable going from the front of the block to the frame where it meets another cable that goes to the neg battery terminal.
On the 12V+ side, I have a 12g wire running from the fuse block through the ignition switch and back through a connector on the back of the fuse block directly to the starter terminal. There is no additional relay(s) in the circuit.
The + side of circuit is pretty much stock 66 Chevelle with the new correct wire end for the starter soldered to the end. So that wire is 58 years old.
Is there a way to ďload testĒ the circuit so I can see what might be drawing the voltage down to 6v?
Iím out of ideas.
