Hustler Sport Model 930198 Won't Start

The mower has the 17.5 HP B&S motor and I went to crank it up all it would do is clicking from the Solenoid Relay. Tried it again and it crunk up and I cut the grass. Parked it in mymy lean too and turned off. Went back out to crank it again and nothing. I have cleand every connection and lightly coated the connections with Electrical dope. Very light. Checked all ground and coated them as well. Battery has a full charge and clean connections. Jumped out the seat switch so I could work on it without having to sit down. Checked the two neutral switch's and they make and break when moving the arms in and out to park. The problem is other than needing a new start solenoid, I have a voltage drop when turning on the key even though I disconnected the wire from the start relay to the solenoid terminal. I get 11 volts into the ignition switch but turning it to the on position I get a voltage drop to 6 or 7 volts. I have removed the ignition switch and the PTO engage switch and ohm'd them out across the corresponding terminals on the wiring diagram and they check good. Also bought 2 new relay switch's for the Start Relay and Kill Relay, they both had the same part number on them 896H-1CH-S1-R1-T I am at a loss as to why the voltage drop? The 15 amp fuse is good. Any help from some of the gurus on here is much appreciated.

Follow the wires back to the battery and find where the voltage drop/s are.

It could still be the connectors, not really tight, or still a some corrosion on them, or the wires themselves can be corroded, either between the wire and the connector, or even the wire itself, under the insulation.

Retraced every wire and ohm them out, all good to infinity, no corrosion. Recleaned every connector using a finger nail file to make sure no rust or corrosion is on the spade terminals and that the terminals are tight fitting. Put the charger on slow charge even though the battery is showing fully charged. Tomorrow I will pull the key switch and PTO switch back out and recheck them as well. So far it has me stumped and I am pretty good at fixing mowers and motors but this has me baffled.

I would suggest instead of ohming them, to leave them connected as part of the circuit, and go from connection point to connection point, and see where the voltage drop/s happen. Where it drops from 11-12V to 6V, should tell you where the problem, be it from one end of a wire to the other end, or one side of a switch to the other side.

Found what it was, the battery itself is failing under any load. Voltage shows good when no load but turn the key on and it drops to 6 volts. Go figure. Thanks for the forum and replies.
