My guess is a bad connection.
I would volt drop the system
The link above describes it better than I could.
The idea of it is:
Electrical current wants to flow thru the wire and starter the way it was desined.
It does not want to go thru the impedence (resistance) of the voltmeter.
Think of it as a water stream
Water wants to go straight down the stream.
If you put another route for the stream to go but it is uphill then the water will not flow because it can just go down the stream.

Now if we add a dam to the stream then the water will start to back up and go up the hill and some water will bypass the dam (resistance)

The idea of the the volt drop test is just measuring how much electrical current is bypassing the wire or starter or what ever.

The more the voltmeter reads means the more it has a bad connection.

For instance
Put the positive lead on the battery positive terminal and the negative on the battey post clamp.
If the voltmeter is reading 12 volts, that means that the connection is no good even if it looks good.
Lets think of a fuse.
Put the pos lead on the power side and the neg on the out. If fuse is good then reading should be zero. If voltage is 12 then that means all voltage has to go thru meter and the fuse is blown.
Any how
Site will explain it better then I can.
Might be batt or starter went belly up also. That will come out in the test.
