Need advice. I have a VN1700 classic tourer 63 plate my headlights wont come on also the alternator won't charge too. Looking at the wiring diagram they seem to be connected to the same relay. Where is this relay located? I have checked the two relays under seat next to tilt switch, both are working fine. There is also a relay box with 3 plugs next to another unit with 2 large plugs connected i think this is ECU is the 3 plug relay for headlights? We found a short in the tail light but tail lights, break lights and small light to front of bike all working and fuses not blowing. Battery seems ok it keeps a charge when off trickle charge. Any advice would be much appreciated.
