Hi guys can someone shed some advice if possible.
Just brought a '92 dio 50 for my step son.
It has a new battery,it starts well all the indicators and horn brake light are strong and steady but the headlight and tail are very weak.
There is a small increase in brightness when revving the engine.
I checked the bulb it is a 12v 30 watt which is what it should be.
Any ideas you bright sparks?
