A charge malfunction on the road is very unlucky situation. Especially if help is far far away.
TX750 and XS650 doesn't have any warning for this. Finally battery gets empty and engine stops.
To improve useful and maybe a bit preventive structure here we can connect a warning lamp. Just like it has done in many cars. At least you may get a bit longer driving range switching lights off.
Basic structure in TX750 is to feed alternator field through regulator from main switch. This means that field coil takes 2...3 amps whole time when engine is not running and switch is on. If you forget switch on for longer time your battery might get empty. Depending on if ignition pointer is closed.
I made a warning lamp connection. I had to add three additional diodes to rectifier. 5A 100 V diodes will be fine. Also I had to add one extra wire from meter unit to regulator.
Generator will be woken up with warning lamp current. When alternator wakes up field diodes will maintain field current.
Warning light will lit if some failure appears.
See Bosch type connection of field diodes (isolation diodes) and regulator connection here.

To attain best possible result I changed also old conventional coil/point operating regulator to an electronic model.
Three 5A 100V field diodes added to rectifier unit. I spread some Sikaflex S221 sealant mass over diodes to prevent vibration and moisture/corrosion
Conventional regulator changer to electronic model
Warning lamp added to meter unit
I hope you'll find something useful here.
