Controls inside us (5) - think answer may be reins but don't know why

Faulty current collector with apparent fivefold chart (10) think answer may be pentagraph

A spike obtained from indigo (7) think answer may be isatine

If anyone can confirm or correct will be very grateful. Thanks

A spike is a tine
