Where to start?, Starter issues... Options

[highways]

Ok, so I've had my 73 2.0L running for 4 months as my daily driver. Now I'm having some starting issues.

When the engine is warm, I turn the key and get a click noise from the starter... and that's all. Have new ground strap on transmission, good ground cable at the battery...

There is a little funkyness going on with my turn signals and emergency brake light... brake light general warning light is always blinking. And the turn signals usually give one click in the right direction (usually at double brightness on the indicator) then they sort of short out and both turn signal indicators blink dimly.. although the actual turn signal light seems to work normally. I might have something backwards in my dash instrument panel. Other then that- the car seems electrically ok.

Where would you start on the starter problem? Stuck selinoid? Low amperage? Time for a hot start bosch kit? The battery has been getting warm as well while driving. Been swaping out voltage regulators and alternators... currently it runs at 14 volts possibly overcharging the batteryh the best regulator and alternator I could find (rebuilt).
