1. For the lack of idiot lights, do as John advises: check simple things first, like fuses and connections. If none of them are working, it has to be something common - for example, there's a connector block that serves them all.
2. For the starter motor not turning:
A much, much, much discussed topic

. And a right royal PITA (and I'm being polite).
Even in the best of conditions, the starter motor struggles, I'm afraid. Down to a gearing fault, as much as anything.
So, long story short:
1. Fit a battery with the most CCA you can find. For you in the States, Westco do one that I rate highly. It delivers 275CC. Model is
12V20P.
2. Change the starter cables for the biggest you can physically fit. 6 gauge works. Make sure the ground strap is good and its connection is very clean.
3. Change the solenoid. Nothing special here, it's just that the original Hitachi unit can be improved on, particularly after 30 years or so. Units from Suzuki, Triumph, Yamaha - all have been used with success. Just check physical size and type of connection.
4. The original starter motor brushes are soft and wear quickly. This leaves carbon residue all over the commutator which greatly reduces the performance of the already struggling starter. Replacement brushes from Nippon Denso can (apparently) still be found, but there are other (possibly better) alternatives too.
(You can modify the starter to have 4 brushes using Honda components. Me, I found this made little or no improvement).
3. You MUST bridge the side stand cut-out, if this has not already been done. Otherwise, one day you will go over a bump in the road, the side stand will jolt down and the engine will cut out. "Dangerous", does not do it justice.
